Chapter # 7 Population – Solved Past Papers MCQs

 In 1979, Pakistan allowed huge numbers of Afghan Refugees to settle in Pakistan. This settlement continued for several years. What were the negative effects of this migration?

The increase in population results in multiple effects including

I.   Environmental degradation.

II.  Burden on housing facilities.

III.  Unstable law and order situation.

IV.  More allocation of developmental funds.

A) I and II

B) II and IV

C) I, II and III

D) I, III and IV

Correct Answer C) I, II, and III

Explanation: I. Environmental degradation: An increase in population, including the influx of Afghan refugees, can lead to overuse of natural resources, pollution, deforestation, and other forms of environmental damage. II. Burden on housing facilities: A sudden rise in population due to migration puts pressure on housing infrastructure, leading to overcrowding and a shortage of adequate living spaces. III. Unstable law and order situation: Rapid population growth or migration can strain public services and resources, leading to tensions, increased crime, and challenges in maintaining law and order. IV. More allocation of developmental funds: While this may also happen, it is not a negative effect; rather, it represents an adjustment in response to increased population demands. Hence, this option is excluded from the correct answer.

Therefore, the negative effects of this migration are best captured by I, II, and III.

Amongst the provinces of Pakistan, Balochistan has the lowest density of population because

A) There is heavy rainfall in Balochistan.

B) There is a scarcity of natural resources in Balochistan.

C) Most parts of Balochistan are comprised of deserts and mountains.

D) Majority of people have migrated away from Balochistan to other parts of Pakistan.

Correct Answer C) Cost parts of Balochistan comprises of deserts and mountains.

Explanation: Balochistan has the lowest population density among the provinces of Pakistan because much of its terrain consists of deserts and mountains, which make it difficult for large-scale human settlement, agriculture, and infrastructure development. A. Heavy rainfall is not a characteristic of Balochistan, which is known for its arid and dry climate. B. Scarcity of natural resources is not entirely true, as Balochistan has significant mineral resources, though the challenging terrain limits habitation. D. Migration away from Balochistan does not explain the historically low population density as much as the geographical features do.

Therefore, the harsh and rugged terrain is the primary reason for the province’s low population density.

Rahim migrated from a rural area to an urban area of Pakistan.  Which of the following rural push factors contributed to his migration?

A) Better health facilities

B) Better educational facilities

C) Lack of natural beauty in the areas

D) Lack of employment opportunities

Correct Answer D) Lack of employment opportunities

Explanation: Rural push factors are conditions in rural areas that encourage people to leave and migrate to urban areas. One of the most significant push factors is the lack of employment opportunities, which drives individuals like Rahim to seek better job prospects in cities. A. Better health facilities and B. Better educational facilities are examples of urban pull factors, which attract people to cities rather than pushing them out of rural areas. C. Lack of natural beauty is not a typical push factor influencing migration decisions. Thus, lack of employment opportunities is the main reason Rahim might have migrated from a rural area to an urban area.

As compared to rural areas of Pakistan, the major cause of air pollution in urban areas of Pakistan is:

A) Solid waste

B) Insecticides

C) Deforestation

D) Vehicular emission

Correct Answer D) Vehicular emission

Explanation: Vehicular emissions are a primary source of air pollution in urban areas, where there is a higher concentration of vehicles compared to rural areas. The exhaust from cars, buses, trucks, and motorcycles releases harmful gases like carbon monoxide and nitrogen oxides, contributing significantly to urban air pollution. Solid waste (option A) and deforestation (option C) do contribute to pollution but are more prevalent in other contexts, while insecticides (option B) typically contribute to pollution in agricultural settings rather than urban ones.

A country can be called overpopulated when:

A) There is an imbalance between birth and death rate.

B) Population is not supported by the available resources.

C) There is an increase in the number of dependents.

D) There is inflation in the country.

Correct Answer B) Population is not supported by the available resources.

Explanation: A country is considered overpopulated when its population exceeds the capacity of its available resources (like food, water, and land) to sustain them. This results in a strain on infrastructure, services, and the environment. An imbalance between birth and death rate (option A) or an increase in dependents (option C) might contribute to population growth but do not necessarily indicate overpopulation unless the resources cannot meet the needs of the population. Inflation (option D) is related to economic factors but does not directly define overpopulation.
