Question

read the sentence.
the garden was enclosed by tall stone walls, which blocked out the noise and bustle of the city.
which statement best explains how the underlined clause conveys meaning?
○ it describes the effect of the tall stone walls.
○ it explains when the garden was enclosed by walls.
○ it modifies the subject and describes the garden.
○ it modifies the verb and describes the enclosure.

Explanation:

The underlined clause is a relative clause modifying "tall stone walls". The walls' effect is blocking city noise/bustle. The second option is wrong (no time info). Third: the clause modifies walls, not the garden (subject). Fourth: it modifies a noun (walls), not a verb. So the first option is correct.

Answer:

A. It describes the effect of the tall stone walls.
