Hmmm, is this the whole question?
Imagery has a lot of effects. Especially on the mind. The idea of imagery is to use words/phrases to describe an event or thing, so that the reader can <span>visualise a picture of what the author is trying to describe.</span>
<span>The question is asking us to find the simple subject in the following sentence:
The space shuttles have made travel to the International Space Station convenient and possible.
First, the whole subject is "the space shuttles" and the head of this phrase is B. shuttles - that's the correct answer</span>
