Light reaction stage occurs during the day or in the presence of light. The light energy or solar energy is captured by chlorophyll and electrons are excited. The energy trapped is used to split water into hydrogen ion(H+) and hydroxyl ion (OH-). The splitting if water into hydrogen ion(H+) and hydroxyl ion(OH-) is called photolysis of water.
The photolysis of water is represented by this equation:
4H2O light 4H+ + 4(OH)
The hydroxyl ion is converted into water :
4(OH) ---> 2H2O + O2
During this process, oxygen is given out as a by product as shown in the chemical equation above. At the same time, a compound, co-enzyme or NADP is reduced by hydrogen ion to NADPH and Air.

(i)The theme of Colonialist Arrogance and expectation; Whitehead comes to Mandoland with a blatant air of superiority with is why after two days of arrival inn the land he refuse to pay homage to king sangi until kindo forces him. This is reflective of colonial arrogance inn history. Even though the real colonial colonial mission is to exploit, They still engage the owner of the land in service labour to advance that interest and also expect to mass him honour and for him for pittance. It is also a show of colonial arrogance that makes whitehead introduce gin spirit drink in place of the peoples local drink mamapama which is congenial with their system, whereas whitehead’s drink intoxicates
and makes the animal of the people.
(ii)The theme of Patriotism and Resistance to Oppression; The patriootic zeal of kindo saves Mando Kingdom from the hands of whitehead. when whitehead refuses to accord kig santigi his deserved respect, it is kindo who restore it by putting him where he truly belongs – beneath the king’s feet. Kindo constantly monitors maligu and soko when he suspects they are in league with whitehead. He also interrogates whitehead on why he chose Mandoland and not another place. when whitehead get the people drunk and the woman become sexually provocative, It is kindo that also calls whitehead and maligu to order. kindo it is that also unveils the grand design to steal mando’s diamond wealth. in the end kindo does not only resist oppression, he stamps it out by killing whitehead.
(iii)The theme of Irony of Culture;Its is a cultural irony that the culture whitehead disregards by introducing the people to alcohol, tobacco, and hard core hallucination drugs, he also finds in it a substance to manipulate the culture by relying on key traditional beliefs that favour his ominous ploy. For example, he seizes on the decree of the death for anyone who kills in peacetime, so as to trap kindo. He also describes diamond as evil stones that should be handed over to him in a land purification ritual he trumps up.

Deceit; plays a pivotal part in this play by Oliver Goldsmith, but I believe it is more like a motif than the theme itself. Almost all of the characters are involved in some sort of deception, both in the main plot and in the subplots, but one must ask oneself what the author is trying to show through these complicated deceptions. Is deception in and of itself the theme, or does it lead to the theme. There is much debate regarding whether this play is a romantic comedy, a comedy of errors, a comedy of manners,a farce, a satire, etc. If you do some research on these comedy genres, you will be able to decide for yourself what you think. Then, you will be able to arrive at the theme of the play. What is the author trying to show with these many deceptions? What is he criticizing? Is the play's theme contemporary, or is it more universal? In other words Much of this play's comedy comes from the trickery played by various characters. The most important deceits come from Tony, including his lie about Hardcastle's home and his scheme of driving his mother and Constance around in circles. However, deceit also touches to the center of the play's more major themes. In a sense, the only reason anyone learns anything about their deep assumptions about class and behavior is because they are duped into seeing characters in different ways. This truth is most clear with Marlow and his shifting perspective on Kate, but it also is true for the Hardcastles and Sir Charles, who are able to see the contradictions in others because of what Deceit engenders.

(i)The theme of life in the past:
In the poem, the poet reflects on the way of life of his fore-fathers He recollects the traditional way of worship with its appurtenances He describes it thus:
"The trapping of the past, tender and
Tenuous woven with fibre of sisal
And washed in the blood of the goat
In the fetish hut" The poet says that his generation is still atuned to the custom and the way of life of the past as the old ways have their influence on the present age. "Determined to ignore these we use snatches from their tunes"...And listen to the reverberation of our songs
In the splash and moan of the sea"
(ii)The theme of cultural assimilation
The poet seems to suggest that his generation has undergone cultural transformation in order to open up a new leases of life. He posit thus; _
"In the forging house of a new life
Transforming the pangs into joy of new songs the whirlpool of the many rivers' estuany determined to ignore these we use Snatches from their tunes. Makes ourselves New flags of anthems
While we lift high the banner of the land"
(iii)The theme of the need to preserve the old tradition: Although the poet personae expresses his joy and excitement at the dawn of a new day, he however still believes that some values of the time past must not be done away with. In conveying this thought, the poet personae puts himself across thus;
" sew the old days for uS, our fathers, that We can wear them under our garment After we have washed ourselves in
The whirlpool of many river's estuary

(i)Imagery: Imagery is used to make readers perceive things involving their five senses. For example, “Sunset and evening star”; “But such a tide as moving seems asleep” and “I hope to see my Pilot face to face.”
(ii)Symbolism: Symbolism is a use of symbols to signify ideas and qualities and give meanings different from their literal meanings. “Evening” symbolizes death and the end of life and “twilight” is the symbol of last moments of life or old age.
(iii)Personification: Personification is to give human characteristics to inanimate objects. For example, in the third line, ‘And may there be no moaning of the bar’ the poet personifies “sandbar”; in the fifth line ‘But such a tide as moving seems asleep’ he personifies the tide as if it can sleep like humans.

Write an article suitable for publication in a national daily on effects of incessant strikes by the Academic Staff Union of Universities (ASUU) and suggest ways of putting an end to them;When two elephants fight, it’s the grass that suffers the most. This is a semblance of what transpired between the federal government and the Academic Staff Union of Universities (ASUU) as students become the grass that are trampled upon each time a strike ensued. The incessant strike of academic staff union of universities has so many effects which includes:
The strike had brought academic activities in most Nigerian public universities to a halt. This disagreement between government and the academic unions often result in deadlock that usually disrupts academic calendar.
.
Despite the poor research and innovation capability of the present set of universities, incessant strike will continue to jeopardize the little research they are undertaking. Because the kind of research and development activities that can put Nigeria in the league of developed nation cannot take place in a disruptive environment like the one we are currently witnessing in our universities. It is, therefore, clear that the current ASUU strike will have negative effect on our industries and from there our Gross Domestic Products (GDP).
.
Incessant strike action by ASUU reduces the academic performances of students, even as most prolonged strikes distort the school calendar. As a result, students who are supposed to do a four- year course end up spending six years in the school for a simple programme.
.
Also, despite the poor research and innovation capability of the present set of universities, experts say incessant strikes will continue to jeopardise the research they are undertaking. Strike, according to experts said also has the tendency of leading undergraduates into some social vices like prostitution, oil bunkering, among others.
.
More so, it is believe that there is a direct connection between economic development and educational growth. The monetary cost of any lost working day to ASUU strike is huge as it runs into billions of Naira, both in terms of salaries and wages, amongst others.
The incessant strike of ASUU could be solved through the following strategies:
.
Firstly, recommending a reevaluation of the education sector, because what often leads to strike in tertiary institutions should be addressed. ‘There is no doubt that the infrastructure in most of the schools are as old as the years of the schools, which is unacceptable,’ as stressed by ASUU. This thus needs to catered for.
.
Secondly, government should always try to honour whatever agreement was reached with the academic unions as most protracted strikes can be averted if necessary steps are taken to build a good relationship between both parties.
.
Thirdly, is through University autonomy incentivises where individual universities is to pursue innovative methods of raising funds beyond tuitions and government budgets. University autonomy will, especially, deepen research capabilities and building of partnerships within the tertiary education system. This policy will also change university leadership and governance, thereby insulating the institutions from political appointment of vice chancellors that has, over the decades, compromised academic quality and performance.

Dear Sir,
CONTINUOUS PAYMENT OF SSCE REGISTRATION FEE
I heartily congratulates you Mr Governor in your recent victory as the Executive Governor of our beloved state. I hope your tenure brings forth good tidings for our dear state, Amen. I write to you as a concerned student in our beloved state. I am writing on the recent order that will soon be implemented in the state that is the government under your watch is about to stop the payment of the registration for senior school certificate examination for students in this state. I would love to inform you through this medium the implications of such action and why you should continue with this good gesture.
.
To begin with, considering the level of poverty in the country, it is difficult for parents to shoulder the burden that comes the senior school certificate. If the government should stop paying this fees, it will lead to massive dropout of students in the secondary school because there will be no hope of paying the fees and the dropout will constitute nuisance in the state.
.
In addition, as you know as an educational elite that you are sir, denying the final class of senior secondary school is like denying them the purpose of schooling. If you withdraw the support they ought to enjoy by paying for this exam. It might cause the junior students to stay away from school which will cause a complete disaster to the state. It will also lead them to other social vices.
However, I will be glad if you can Rescind this decision to stop paying for the senior school certificate examination. It will go a long way in giving a level playing ground between the social class of the society. The rich and the poor need to break the dichotomy that exist between them and giving them a level playing ground to show their intellectual capabilities and move to the next stage of their education will go a long way in breaking the dichotomy.
.
In conclusion, your excellency, critically looking at it, if this fees are removed and the burden of payment shift to the parents, those who cannot afford this fees can resort to dubious and fraudulent means to get the money, this will bring about criminals in the education system. I will be glad if my writings can be put into consideration and the government continue to pay the fees attached to the senior secondary school certificate examination. Thanks in anticipation

In addition, as you know as an educational elite that you are sir, denying the final class of senior secondary school is like denying them the purpose of schooling. If you withdraw the support they ought to enjoy by paying for this exam. It might cause the junior students to stay away from school which will cause a complete disaster to the state. It will also lead them to other social vices.
However, I will be glad if you can Rescind this decision to stop paying for the senior school certificate examination. It will go a long way in giving a level playing ground between the social class of the society. The rich and the poor need to break the dichotomy that exist between them and giving them a level playing ground to show their intellectual capabilities and move to the next stage of their education will go a long way in breaking the dichotomy.
.
In conclusion, your excellency, critically looking at it, if this fees are removed and the burden of payment shift to the parents, those who cannot afford this fees can resort to dubious and fraudulent means to get the money, this will bring about criminals in the education system. I will be glad if my writings can be put into consideration and the government continue to pay the fees attached to the senior secondary school certificate examination. Thanks in anticipation

Write an article suitable for publication in a national daily on effects of incessant strikes by the Academic Staff Union of Universities (ASUU) and suggest ways of putting an end to them;When two elephants fight, it’s the grass that suffers the most. This is a semblance of what transpired between the federal government and the Academic Staff Union of Universities (ASUU) as students become the grass that are trampled upon each time a strike ensued. The incessant strike of academic staff union of universities has so many effects which includes:
The strike had brought academic activities in most Nigerian public universities to a halt. This disagreement between government and the academic unions often result in deadlock that usually disrupts academic calendar.
.
Despite the poor research and innovation capability of the present set of universities, incessant strike will continue to jeopardize the little research they are undertaking. Because the kind of research and development activities that can put Nigeria in the league of developed nation cannot take place in a disruptive environment like the one we are currently witnessing in our universities. It is, therefore, clear that the current ASUU strike will have negative effect on our industries and from there our Gross Domestic Products (GDP).
.
Incessant strike action by ASUU reduces the academic performances of students, even as most prolonged strikes distort the school calendar. As a result, students who are supposed to do a four- year course end up spending six years in the school for a simple programme.
.
Also, despite the poor research and innovation capability of the present set of universities, experts say incessant strikes will continue to jeopardise the research they are undertaking. Strike, according to experts said also has the tendency of leading undergraduates into some social vices like prostitution, oil bunkering, among others.
.
More so, it is believe that there is a direct connection between economic development and educational growth. The monetary cost of any lost working day to ASUU strike is huge as it runs into billions of Naira, both in terms of salaries and wages, amongst others.
The incessant strike of ASUU could be solved through the following strategies:
.
Firstly, recommending a reevaluation of the education sector, because what often leads to strike in tertiary institutions should be addressed. ‘There is no doubt that the infrastructure in most of the schools are as old as the years of the schools, which is unacceptable,’ as stressed by ASUU. This thus needs to catered for.
.
Secondly, government should always try to honour whatever agreement was reached with the academic unions as most protracted strikes can be averted if necessary steps are taken to build a good relationship between both parties.
.
Thirdly, is through University autonomy incentivises where individual universities is to pursue innovative methods of raising funds beyond tuitions and government budgets. University autonomy will, especially, deepen research capabilities and building of partnerships within the tertiary education system. This policy will also change university leadership and governance, thereby insulating the institutions from political appointment of vice chancellors that has, over the decades, compromised academic quality and performance.

In addition, as you know as an educational elite that you are sir, denying the final class of senior secondary school is like denying them the purpose of schooling. If you withdraw the support they ought to enjoy by paying for this exam. It might cause the junior students to stay away from school which will cause a complete disaster to the state. It will also lead them to other social vices.
However, I will be glad if you can Rescind this decision to stop paying for the senior school certificate examination. It will go a long way in giving a level playing ground between the social class of the society. The rich and the poor need to break the dichotomy that exist between them and giving them a level playing ground to show their intellectual capabilities and move to the next stage of their education will go a long way in breaking the dichotomy.

(NO2)
According to one traditional account, the original people and founders of the Benin Empire, the Bini (or Edo people), were initially ruled by the Ogisos (Kings of the Sky). The city of Ibinu (later called Benin City) was founded in 1180 C.E.
.
About 36 known Ogiso are accounted for as rulers of the empire. On the death of the last Ogiso, his son and heir apparent Ekaladerhan was banished from Benin as a result of one of the Queens changing the message from the oracle to the Ogiso. Ekaladerhan was a powerful warrior and well loved Prince. On leaving Benin he travelled to the west of the present day Nigeria to the land of the Yorubas. At that time the Yoruba oracle said that their King will come out of the forest and when Ekaladerhan arrived at Ife, he was received as a King.
.
He changed his name to Imadoduwa meaning "I did not misplace my royalty" and became The Great Oduduwa of The Yoruba Land. On the death of his father, the last Ogiso, a group of Benin Chiefs led by Chief Oliha came to Ife, pleading with him to come back to Benin to ascend the throne. Oduduwa's reply was that a King cannot leave his Kingdom but he had seven sons and would ask one of them to go back to Benin to rule as the next King.
.
Oranmiyan, the son of Ekaladerhan aka Oduduwa, agreed to go to Benin. He spent some years in Benin and came back to Ife after his wife gave birth to a son named Eweka. Eweka I became the first Oba of Benin. In 1440, Oba Ewuare (Ewuare the Great) came to power and turned the city-state into an empire. Around 1470, he named the new state Edo.

6) Discuss the factors that led to the rise of old oyo empire
••••••••••••••••••••••••••••••••••••
Many factors were responsible for the rise of old oyo empire part if which is
.
1) Able Leadership; oyo was fortunate to have able,wise and warlike leaders the like Aalafin gaha, Aalafin Abiodun they were brave and agile.
.
2)Geographical Location; this favoured old oyo as it was situated in an open area thus encouraging expansion also attack from south is difficult with the presence of deep forest.
.
3) Bouyant Economy; thier bouyant economy tremendously helped thier rise agricultural pruduce, domestication of animals,artwork,
.
figurines,exchanging of goods with thier neighbouring towns the economy was highly diversify they also got involved in trade as katunga was towards trans-sharan trade route
.
4) Dynamic army\Military Command ; they have a dynamic military formation Aare-ona kakanfo as the chief commander of the army, with 70 eshos dividing them 10/10 to 7 oyo mesi the military comprises of young men and hunters. In the same vein
.
5) Type of Government;there is check and balance whenever the aalafin can not rule arbitrarily, the oyomesi were vested with power to checkmate the Aalafin they too were headed by Bashorun the prime minister
.
(6)
(i)Executive Powers; The Oba's were the chief administrators of the Yoruba states; they exercised executive powers over all the people of the Empire. Oba's pay tribute to the Alaafin in respect to their ancestral home, and those tributes were also a source of wealth to the empire.
.
(ii)Legislative Powers; The powers of the Alaafin were checked by a group of "Kingmakers" called the Oyomesi. They exercised legislative functions and was headed by the Bashorun. The Bashorun plays a vital role in the formation of the empire, and has the power to impeach either the Alaafin of the Oba's.
.
(iii)Judicial Powers; Oyo Empire was very decentralized in nature and powers were distributed among several bodies to prevent authoritarianism. The powers of the Oyomesi were in turn, checked by the presence of the Ogboni Fraternity. The Ogboni was considered to be very scared and commonly referred to as "The Mouthpiece of the Gods"; with their office headed by the Ifa Priest.
.
(iv)Early Period; It is pivotal to note that the rich culture of the Yoruba's cut across the shores of Africa and even to Southern America. Oyo Empire was well known for it's industrial productions in brass making. Because of its wealth and military skills, Old Oyo was - and still remains - the most important and authoritative faction of all early Yoruba principalities.

eo = 4×10^4 kg/m^3
Mo = 0.4kg
Vo = ?
eL = 1.2×10^2 kg/m^3
Where,
eo = Density of object
Mo = mass of object
Vo = volume of object
eo = Mo/Vo
Vo = Mo/eo = 0.4/4×10^4
Vo = 0.00001m^3
Mo in the liquid = eL × Vo
= 1.2×10^2 × Vo × 3/4
= (1.2×10^2 × 0.00001×3)/4
