UNN Post UTME Questions and answers 2021

Read the passage carefully and answer the questions that follow. Developments in electronic science have transformed the art of record-keeping in the modern age. Traditionally, records of events were kept only in people’s minds. It depended very much on the retentive power of human memory. This was extremely dangerous as people either forgot events wholly or in part, or deliberately falsified details to suit their various interests. Interminable arguments were thus the order of the day. Even writing which replaced mental recording was not entirely free from these shortcomings as untruths could be written as true records either willingly or inadvertently. With the adve t of the electronic memory, however, these dangers now show not only what happened, but also who did or said what, including how and when.

  1. The author believes that electronic

recording is _____.

  1. superior to mental recording.
  2. inferior to both mental recording and

writing.

  1. superior to both mental recording and

writing.

  1. inferior to only writing.

 

  1. The writer believes that the art of record

keeping has _____.

  1. improved over the years
  2. endangered the art of writing
  3. changed human memory.
  4. overcome all the problems facing it
  5. How many stages of development did the

writer mention while discussing the art of

record keeping?

  1. Two
  2. Three
  3. Four
  4. Five
  5. According to the author, human memory is

unreliable because people _____.

  1. die and we forget what they said
  2. forget events or tell lies
  3. do not always know when events happen
  4. do not always know who did what and

when

  1. From the passage, we gather that writing

is almost

  1. as unreliable as human memory
  2. as reliable as electronic memory
  3. more reliable than electronic recording
  4. not to be compared to any other recording

systems

to spend the day at the market, a woman

would walk all the way from her village to

town with half a dozen eggs. She would

spread them on a little bit of ground for

which she paid rent. Through the day she

would squat on the ground and talk to others

who came for the same reason. She would

refuse to sell her wares till it was time to

leave. They were the excuse for her being

there. There were many like that. But there

COMPREHENSION

INSTRUCTION: Read the passage carefully

and answer the questions that follow.

The approach to the university is being

restructured to ease the flow of traffic, give

better security and provide an appropriate

introduction to a seat of higher learning. The

Works and Services Complex is also under

construction, and we intend to move into the

completed (major) part of it within the next

few weeks.

All these projects are being executed with an

eye to aesthetics, for we recognize the

important influence of a beautiful and healthy

environment on its inhabitants and feel that a

cluster of buildings on a small space such as

we have, should be so well designed as to

have a beneficial psychological and

sociological effect on all members of the

community.

I have gone to these lengths to itemize these

examples of current development for two

main reasons. Firstly, to advise you that the

road diversions and other physical

inconveniences currently being experienced

will be on the increase because of intense

development activity. We therefore appeal to

you to bear with us in full knowledge and

consolation that such inconveniences are

temporary and will soon yield final tangible

results. Secondly, to demonstrate our

capacity for executing approved projects with

dispatch. and to assure Government that we

are up to the task. Indeed. I can assure

Government that its ability to disburse funds

to us will be more than matched by our

capacity to collect and expend them on

executing various worthy projects in record

time.

  2. beneficial psychological effects
  3. regard for health
  4. consideration for beauty
  5. a cluster of buildings
  6. In this passage, the author tries to explain

why.

  1. it is necessary to establish the Works and

Services Complex in the University

  1. beauty should not be taken into

consideration when building on such a small

space as we have

  1. the gateway to the university is being

rebuilt

  1. a major part of the project should be

completed in the next few weeks

  1. visitors should be debarred from using the

gates in the meantime

  1. Which of these is NOT among the reasons

given by the author for enumerating the

examples of the current development?

  1. To show that we are capable of executing

approved projects

  1. To convince the government that we can

be trusted with tasks

  1. The inconvenience currently being

experienced will go on indefinitely.

  1. We are fully aware of the inconveniences

being caused but we do not want you to

complain.

INSTRUCTION: Read the passage carefully

and answer questions 1-5 below.

Olumba removed a small black amulet from

his neck and substituted a bigger one. The

former was for general protection at home,

the latter for protection and luck whilst

travelling. Ready at last he picked up his

matchet and headed for the chief’s house

with Ikechi behind him.

Olumba walked ahead looking upward as

usual. Just what he was searching for in the

sky Ikechi couldn’t tell. Perhaps, his

shortness accounted for this habit since he

often had to look up into the faces of his

taller companions. What he lacked in height

he made up in solid muscle and he looked

strong. His wrestling pseudonym was

Agadaga, a name which meant nothing but

which somehow conveyed an impression of

strength.

Eze Diali, the chief, sat at one end of his

reception hall ringed by the village elders

whom he had called to a meeting. The rest of

the hall was filled with much younger men.

“People of Chiolu,” the chief began, “I have

learnt that poachers from Aliakoro ‘will be at

the Great Ponds tonight. There is no doubt

that they will try to steal from the Pond of

Wagaba which as you know is rich in fish.

Our plan tonight is to bring one or more of

these thieves home alive and ask for very

large ransoms. This line of action will have

two effects. Firstly. it will prove our charges

of poaching against the people of Aliakoro,

and secondly, the payment of very large

ransoms would be a deterrent. We need

seven men for this venture. I call for

volunteers.”

“Who will head this party?” the Chief asked,

looking around. Chituru, one of the elders,

said: “Eze Diali, let us not waste time.

Olumba is the man for the job. We all know

that he has led many exploits like this one.”

“We still need six men,” Eze Diali said. Eager

youths came surging forward. Their wellformed muscles rippled as they elbowed one

another. It was difficult to choose.’

“I suggest Olumba should choose his men.

He knows the boys very well and his

judgment should be reliable.” It was

Wezume, another village elder, who spoke.

  1. Olumba wore amulets because he

________.

  1. was superstitious.

  12. “Poaching” means
  13. stealing
  14. cracking eggs
  15. fishing
  16. deterring thieves
  17. demanding ransoms from Aliakoro

would definitely be poachers from Chiolu at

the Great Ponds that night

Mathematics is the language in which the

Book of Nature is written: Mathematics is the

queen of the sciences. It is universally

agreed that Mathematics is the backbone of

Science and Technology. For without

mathematics, the engineer is but an artist or

a sculptor. He can build his bridge, attest to

its form and beauty, but without

mathematics he cannot guarantee its

reliability to serve the purpose for which it is

built. Mathematics is indeed the science of

sciences. It is also art of all arts. It is right,

legitimate and defensible to consider

mathematics as an Art. The poet, the

musician, the artist and the mathematician

have a lot in common. Fundamental to all

their studies and works is their common

interest in the logical study of related

concepts and objects to form patterns which

will produce beauty, harmony and order.

Thus. the poet arranges words to produce a

pattern called music; the artist arranges

colours to produce a pattern called painting

and the mathematician arranges abstract

ideas into a pattern using symbols, to

produce equations. Each 01. these patterns –

the poem, the music, the painting and the

COMPREHENSION

INSTRUCTION: Read the passage below

carefully and answer the questions 1-5 that

follow.

All over the world till lately, and in most of

the world till today mankind has been

following the course of nature: that is to say,

it has been breeding up to maximum. To let

nature, take her extravagant course in the

reproduction of the human race may have

made sense in an age in which we were also

letting her take her course in decimating

mankind by the casualties of war, pestilence,

and famine. Being human, we have at least

revolted against that senseless waste. We

have started to impose on nature’s heartless

play a humane new order of our own.

But, once man has begun to interfere with

nature, he cannot afford to stop half way. We

cannot, with impunity, cut down the deathrate and at the same time allow the birthrate to go on taking nature’s course. We

must consciously try to establish an

equilibrium or, sooner or later, famine will

stalk aboard again.

1.The author observes that

  1. war, pestilence and famine were caused

by the extravagance of nature.

  1. nature was heartless and senseless.

C purposely try to fight nature.

  1. try to fight nature;
  2. deliberately find a balance.
  3. The main idea of this passage is that

COMPREHENSION

INSTRUCTION: Read the passage

carefully, and answer the questions that

follow it.

Although our aim is to nurture children,

Nigerian children are still subjected to severe

physical, social and mental stress as they

develop. So far, our interest and activities

have been to ensure their physical well-being

through the reduction of high mortality and

morbidity rates, still inadequate as this may

  1. But we need to examine from time to

time the other needs of the Nigerian child

which will ensure a totally healthy

development.

We are split between two cultures our

traditional and the western, a relic of our

colonial past. This also affects our child

rearing practices. Therefore, these practices

must have a very important bearing on how

the child is prepared for our world of today so

that he fits into our different personalities in

terms of motivation, aggressiveness,

achievement and the integration of the

individual into the community socially and

culturally. It is important that, while we

struggle with the visible organic diseases, we

fix our gaze on the other important measure

to attain this one a healthy child.

The process of social adjustment begins from

the moment of birth. Many of our traditional

birth practices ensure that the mother either

carries or suckles her child immediately after

birth. The baby therefore comes into close

contact with the mother at this critical time.

Moreover, she is forced to stay indoors with

the baby for varying periods of time. By this

means, the attachment of the baby to the

mother, so essential for the child’s ability to

relate to her in future, is secured.

This crucial moment in the baby’s life is now

being recognized in western countries, whilst

birth practices in some hospitals and

maternity homes separate mother and child

immediately after birth to the extent that

their ability to develop a close relationship

may be jeopardized. Our Nigerian child of

today may, therefore, be worse off than that

of yesterday. As we move towards the

training of our traditional birth attendants

with a view to incorporating them into our

health services, healthy practices such as the

one described above must be maintained and

encouraged.

  1. In the passage there is an attempt to

explain that to ensure a totally healthy child

  1. it is necessary to concentrate on the

child’s physical well-being alone

  1. it is essential to reduce the high child

mortality and morbidity rate

  1. it is necessary to take care of other things

in addition to the child’s physical well-being

  1. it is important to keep to the rules of

hygiene

  1. it is necessary to copy foreign ways of

bringing up children

  1. It is said that differences in ways of

bringing up children and educating them

  1. achieve the same results
  2. are reflected in the personalities, attitudes

and achievements of the individual

  1. make people aggressive
  2. have nothing to do with educational

attainments

  1. are a matter of the cultural background of

the people

  1. Since the training for social adjustment

begins from the moment of birth, our

traditional practices

  1. are too uncivilized to be helpful
  2. need to be modernized
  3. ate very helpful to the proper growth of

the child

  1. make the child stranger to modern

civilization

  1. are the cause of under-development
  2. In spite of the fact that the western

countries now recognize the importance of

the early period of

childhood in forming a relationship, Nigerian

hospitals and maternity homes

  1. copy the wrong-western practice now

being criticized in western countries .

  1. improve on local practices and the future,

of the child is secure

  1. ensure that the child is brought up in p.ng

INSTRUCTION: Read the passage carefully,

and answer the questions that follow it.

Our planet is at risk. Our environment is

under threat. The air we breathe, the water

we drink, the seas we fish in, and soils we

farm, the forests, animals and plants which

surround us are in danger. New terms and

words describe these problems – acid rain,

the greenhouse effect, global warming, holes

in the ozone layer, desertification and

industrial pollution. We are changing our

environment. More and more gases and

wastes escape from our factories. Rubbish,

oil spillages and detergents damage our

rivers and seas. Forests give us timber and

paper, but their loss results in soil erosion

and also endangers wildlife.

The richer countries of the world are mainly

responsible for industrial pollution. This is

where most of all the commercial energy is

produced. In developing countries, poverty

cause people to change their environment to

overgraze grassland, to cut down trees for

new land and firewood, to farm poor soil for

food.

The United Nations Environmental Protection

Agency says that an area of forest the size of

Sierra Leone disappears every year. Trees

are cut down for timber which is used for

building, furniture, paper and fuel. They are

also destroyed to provide land on which to

graze animals and build new villages and

towns. But trees have many other important

uses. Trees protect the land from heavy

downpour of ram and their roots help to hold

the soil together. Forests are also the home

of many living things. The Amazon forest

contains one fifth of all the species of birds in

the world. In our forests, there may be plants

and animals which could help in the discovery

of new medicines of crops.

To rescue and conserve our beautiful world,

we must act cooperatively. Individuals,

communities, nations and international

associations, all have a responsibility. By

learning to protect the natural environment,

we can manage the earth’s resources for

generations to come.

COMPREHENSION

INSTRUCTION: Read the following passage

carefully, and answer the questions that

follow.

If we examine the opportunities for education

of girls or women in less developed countries,

we usually find a dismal picture. In some

countries, the ratio of boys to girls in

secondary schools is more than seven to one.

What happens to the girls? Often, they are

kept at home to look after younger siblings

and to perform a variety of domestic chores.

Their education is not perceived as in any

way equal in importance to that of the boys.

When a non-literate or barely literate girl

reaches adolescence, she has little or no

qualification for employment, even if her

community provides any opportunity for the

employment of women. The solution is to get

her married as soon as possible, with the

inevitable result that she produces children

too soon, too often and too late. With no

formal education, she is hardly aware that

there is any alternative. In a study made in

Thailand, it was noted that the literate

woman marries later and ceases childbearing

earlier than her non-literate counterpart. But

the latter is so chained in her household by

the necessities of gathering fuel, preparing

food and tending children that she is very

difficult to reach, even if health services,

nutrition, education, maternal and child

health centres are available in her

community. She does not understand what

they are intended to do.

  1. The phrase “a dismal picture” means
  2. a dull show
  3. an interesting show
  4. a sad situation
  5. a dreadful appearance
  6. According to the writer, most girls in less

developed countries are not in school

because

  1. they refuse to be educated
  2. they prefer getting married and having

children

  1. the education of boys is rated higher
  2. the girls have no employment
  3. The non-literate woman is very difficult to

reach because she

  1. does not understand the value of

education and health services

  1. is too far from the city and from school
  2. is not permitted to go out to attend clinics

for health services

  1. can only gather fuel and prepare food
  2. The phrase “too late” as used in the

passage implies that the woman

  1. ought to have stopped producing children

earlier

  1. goes on producing children when she

ought to have stopped

  1. fails to marry early enough for her to

produce children .

  1. had all her children at an advanced age
  2. The writer ’emphasizes that in less

developed countries –

  1. the education of girls is not important
  2. the non-literate woman has some

advantage because she has more

  1. the literate female is a threat to the male

  1. there is a need to give boys and girls

equal opportunities in education
