Q.1
Correct option: B. pop star has been
Explanation: The phrase “Many a” is followed by a singular noun and a singular verb. Therefore, “pop star has been” is correct. “Many a” implies multiple instances but grammatically requires singular agreement.
Q.2
Correct option: D. a little
Explanation: “A little” is used with uncountable nouns like “water.” It indicates a small amount. “Little” would imply almost none, which doesn’t fit the context of putting water in the kettle.
Q.3

Explanation: “Wealth” is an uncountable noun, so “so much” is appropriate. “So many” is used with countable nouns, and the other options are grammatically incorrect.
Q.4
Correct option: B. so many problems
Explanation: “Problems” is a countable noun, so “so many” is correct. “So much” is used for uncountable nouns, and “problem” in singular form doesn’t match the context of not knowing what to do.
Q.5

Explanation: “A lot of” can be used with both countable and uncountable nouns. Here, “students” is plural, so the plural verb “suffer” is correct.
Q.6

Explanation: “Most of” with “population” (singular) requires a singular verb, “lives.” “Populations” would imply multiple groups, which doesn’t fit the context.

Explanation: “Enough” precedes the noun it modifies (“courage”). The phrase “enough courage” is grammatically correct and idiomatic.
Q.8
