In giving directions, which word completes the sentence about finding the garage?

The word "At" is suitable for completing the sentence about finding the garage because it indicates a specific location or point of reference. Using "At" suggests that the garage is a fixed point where someone can arrive or be, which aligns well with how people typically give and understand directions. For example, a sentence might read, "You will find the garage at the end of the street," clearly denoting where the garage is located in relation to the individual’s current position.

In the context of direction giving, the other options imply different relationships that may not convey the intended clarity regarding a location. "Across" would suggest something on the opposite side of a street or space, which introduces ambiguity regarding proximity. "By" might indicate closeness but doesn’t confirm a distinct location. "In" could imply the garage is within another structure, which might not be accurate depending on the context of the directions being given. Thus, "At" presents the clearest instruction for locating the garage.
