Total Questions: 50

31. Which one of the following statements about production possibility frontier is not correct?

Correct Answer: (d) On the production possibility frontier, the output of one commodity can be increased without changing the output of another commodity.
Solution:Production possibility frontier is based on the following assumptions:

1. The amount of resources in an economy is fixed, but these resources can be transferred from one use to another;

2. With the help of given resources, only two goods can be produced;

3. The resources are fully and efficiently utilised;

4. Resources are not equally efficient in production of all products. So, when resources are transferred from production of one good to another, the productivity decreases;

5. The level of technology is assumed to be constant. Point no. 5 negates the statement given in the question as the output of the commodity will remain unchanged as the technology is assumed to be constant.

32. How is the magnitude of price elasticity for an individual good determined?

1. By the degree to which the good is a necessity or luxury

2. By the extent to which substitutes are available

3. By the rate of income growth in the economy

4. By the relative importance of the good in the consumer's budget

Select the correct answer using the code given below.

Correct Answer: (c) 1, 2 and 4
Solution:The income elasticity of demand is used to measure the sensitivity of a change in the quantity demanded relative to a change in consumers' incomes not be the rate of income growth in economy.

Many factors determine the demand elasticity for a product, including price levels, the type of product or service, income levels, and the availability of any potential substitutes.

High-priced products often are highly elastic because, if prices fall, consumers are likely to buy at a lower price.

Compared to essential goods, luxury items are highly elastic.

Goods with many alternatives or competitors are elastic because, as the price of the good rises, consumers shift purchases to substitute items.

Incomes and elasticity are related-as consumer incomes increase, demand for products increases as well.

33. Which one of the following functions as an automatic stabilizer in the context of fiscal and monetary policies of an economy?

Correct Answer: (a) Personal income tax
Solution:The best-known automatic stabilizers are progressively graduated corporate and personal income taxes, and transfer systems such as unemployment insurance and welfare. Automatic stabilizers are called this because they act to stabilize economic cycles and are automatically triggered without additional government action.

Reverse repo, open market operation and bond price affect monetary policy and share markets which are part of money multiplier group.

34. Broadly both birth and death rates are low in which one of the following stages of demographic transition model?

Correct Answer: (d) Low stationary stage
Solution:
  • Fourth stage (Low stationary)- This stage is characterized by low birth and low death rate with the result that the population becomes stationary. Most industrialized countries have gone through a demographic transition from a high birth and high death rates to low birth and low death rates.
  • There is a demographic cycle of 5 stages through which a nation passes.
  • First stage (High stationary): This stage is characterized by a high birth rateand high death rate which cancel each other and the population remainsstationary. Till 1920, India was in this stage.
  • Second stage (Early expanding): The death rate begins to decline while thebirth rate remains unchanged. As the birth rates remain high, the populationstarts to grow rapidly.
  • Third stage (Late expanding)- Death rate declines still further and birth ratetends to fall, but population tends to grow as birth rate supersedes the deathrates, but rates of population growth decelerates.
  • Fourth stage (Low stationary)- This stage is characterized by low birth andlow death rate with the result that the population becomes stationary.
  • Mostindustrialized countries have gone through a demographic transition from ahigh birth and high death rates to low birth and low death rates.
  • Fifth stage (Declining): Population begins to decline because birth rate is lower than death rate.

35. Which one of the following is a pull factor form migration?

Correct Answer: (b) High wage
Solution:
  • Migration is a global phenomenon caused not only by economic factors, but also by social, political, cultural, environmental, health, education and transportation factors.
  • The Pull Factors are factors which attract the migrants to an area. Opportunities for better employment, higher wages, facilities, better working conditions and attractive amenities are pull factors of an area.
  • Pull factors are those that are associated with the area of destination

36. What is the depression at the top of a volcano following a volcanic eruption called?

Correct Answer: (d) Crater
Solution:
  • Depression on top of the volcano formed after volcanic eruption is called Crater.
  • A crater is a bowl-shaped depression, or hollowed-out area, produced by the impact of a meteorite, volcanic activity, or an explosion. This cheery crater on Mars was the result of a happy accident-a meteor impact.
  • A volcanic vent is an opening exposed on the earth's surface where volcanic material is emitted.
  • A cinder cone is a steep conical hill of loose pyroclastic fragments, such as volcanic clinkers, volcanic ash, or cinder that has been built around a volcanic vent.

A magma chamber is a large pool of liquid rock beneath the surface of the Earth. The molten rock, or magma, in such a chamber is less dense than the surrounding country rock, which produces buoyant forces on the magma that tend to drive it upwards.

37. In order to find out the absolute location of a place on the map, which of the following will be required?

Correct Answer: (c) Both latitude and longitude of the place
Solution:Grid reference helps people to locate places on the map. Grid is made up of latitude and longitude lines. Latitude lines run east-west around the globe and longitude lines run north-south direction. Grid lines on map define the coordinate system. Latitude and longitude are imaginary lines that help us label every place on the surface of earth. So, grid references are essential to find the exact location of places on a map.

38. The speed of the wind is measured by

Correct Answer: (d) anemomoter
Solution:
  • An anemometer is an instrument that measures wind speed and wind pressure. Anemometers are important tools for meteorologists, who study weather patterns. The stronger the wind blows, the faster the rod spins.
  • A barometer is a scientific instrument used to measure atmospheric pressure, also called barometric pressure.
  • A weather vane, wind vane, or weathercock is an instrument used for showing the direction of the wind. It is typically used as an architectural ornament to the highest point of a building.
  • A wind rose is a graphic tool used by meteorologists to give a succinct view of how wind speed and direction are typically distributed at a particular location.

39. In the course of a river, in time, which one of the following features is formed when the old meander is closed off by deposition?

Correct Answer: (c) Oxbow lake
Solution:An oxbow lake is formed when a meander is cut off by deposition.

40. Most of the mature Harappan sites in the region of Cholistan had been abandoned during

Correct Answer: (c) C. 1800 ВСЕ
Solution:There is evidence that by c. 1800 BCE most of the Mature Harappan sites in regions such as Cholistan had been abandoned. Simultaneously, there was an expansion of population into new settlements in Gujarat, Haryana and western Uttar Pradesh.
