• Question 4 of 10 4. Question 1 points Why might the internationalization of a currency create a dilemma for a country? a) It always leads to currency depreciation b) It guarantees economic growth c) It eliminates the need for foreign exchange reserves d) It requires balancing global currency supply with domestic monetary policies Correct Solution: D The internationalization of a currency creates a dilemma for a country because it requires balancing the supply of enough currency globally while maintaining domestic monetary policies. This challenge arises from the need to meet international demand for the currency, which can potentially conflict with domestic economic objectives. The country must carefully manage its currency’s role in global markets while ensuring that its monetary policies remain effective for domestic economic stability. This balancing act can be complex, as increased global use of the currency can impact factors such as exchange rates, interest rates, and capital flows, which in turn affect the country’s ability to control its domestic economy.

• Question 5 of 10 5. Question 1 points Consider the following statements about delimitation powers of the State Election Commissions (SEC)s: SECs are responsible for delimiting constituencies for local elections every five years. Delimitation powers of the SEC extend to state assembly constituencies. SECs rely on the voter list prepared by the Election Commission of India for delimitation purposes. How many of the above statements is/are incorrect? a) Only one b) Only two c) All three d) None Correct Solution: B Statement 1 is correct, as SECs are responsible for delimiting constituencies before local elections, such as those for Panchayats and Municipalities, which typically occur every five years.

• Question 8 of 10 8. Question 1 points Why is helium considered a non-renewable resource on Earth? a) It is only found in meteorites b) It is continuously consumed in nuclear fusion on Earth c) Once released into the atmosphere, it escapes into space d) It is chemically reactive and bonds with other elements easily Correct Solution: C Helium is a non-renewable resource on Earth because once it is released into the atmosphere, it escapes into space due to its low atomic mass and inert nature. Helium is primarily obtained from natural gas deposits where it is produced through the radioactive decay of elements like uranium. Because Earth does not have the capacity to retain helium in its atmosphere, the supply of helium is finite, and it cannot be easily replenished, making it a non-renewable resource.
