Select the most appropriate option to fill in the blank.

The main street, which is neither broad nor ______, runs past this square on its way to the railway-station.

narrow

The most appropriate option to fill in the blank is narrow.

The word narrow means not wide. In this case, the sentence is saying that the main street, which is neither broad nor narrow, runs past this square on its way to the railway-station. This means that the main street is not very wide, but it is also not very narrow.

The other options do not make sense in the context of the sentence.

• Shallow means not deep. It cannot be used in this sentence because it does not describe the width of a street.
• Wide means having a great width. It cannot be used in this sentence because it is the opposite of what the sentence is trying to say.
• High means having a great height. It cannot be used in this sentence because it does not describe the width of a street.
