There weren’t any ______ between our gardens and it was very difficult to separate them from each other. ?

In the sentence presented, “There weren’t any ______ between our gardens and it was very difficult to separate them from each other,” the missing word should convey the idea of a physical barrier or division that could distinguish one garden from another.

Option A, “field,” refers to an open area and does not imply separation. Option B, “rock,” while capable of creating some form of division, is not typically used to describe a boundary between gardens. Option D, “grass,” inherently suggests a common feature shared by gardens, thus failing to provide separation.

However, option C, “hedge,” is most appropriate because a hedge is a dense row of shrubs or low trees that can effectively serve as a natural dividing line between properties, particularly in gardens. It provides a visual and physical separation, which aligns perfectly with the context of the sentence, where the absence of such a barrier makes it challenging to distinguish between the two gardens. Thus, the correct answer is “hedge,” as it best fits the intended meaning of separation in the context provided.
