Question

We wasted............ hour, waiting for the rescue team to arrive at the spot.

• A. an
• B. all
• C. a
• D. not

Answer 1

Answer:

A. an

• "We wasted" indicates that time was spent unnecessarily or unproductively.

• "an hour" is the amount of time that was wasted. The indefinite article "an" is used instead of "a" because "hour" starts with a vowel sound.

So, the sentence as a whole means that the speaker and possibly others spent one hour waiting for the rescue team, and that time was spent unnecessarily or unproductively.
