Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. but.
Context: The sentence indicates that despite the farmers taking turns watching, they still could not save the crops. The blank requires a conjunction that conveys contrast.
Meaning of the words:
as: Indicates reason or comparison; does not fit the context.
for: Indicates purpose or reason; inappropriate here.
but: Correctly conveys contrast between the farmers’ efforts and the outcome.
because: Indicates cause; not suitable here.
Correct word: but
Reason: The sentence expresses contrast, showing that even though the farmers tried, the birds still ate the grains. “But” is the appropriate conjunction.
Final sentence: They tried to take turns watching, but still, they were not able to save the crops.
Hence, the chosen option is correct.
