Q1. Choose the most appropriate word to fill in the blank in the given sentence: If they _____________ that picture lower, people would be able to see it.
Explanation
The sentence expresses an unreal or hypothetical present condition: if the picture were placed lower, people would be able to see it. In a second conditional sentence, the if-clause takes the simple past, so “hung” fits correctly. “Hang” is present tense and does not match the hypothetical structure. “Don't hang” gives a negative present meaning, which changes the sentence. “Would hang” is also incorrect because standard second conditional form does not normally use “would” inside the if-clause.
