A speaker would use rhetoric to <span>effectively persuade. This is because when a rhetorical question is asked, the reader keeps on thinking about the answer to a question until they find it in what they are reading and have an "aha" moment.</span>
It should be moved to the beginning of the sentence, that means, that it should be placed before "The motorcycles raced" (option A).
Explanation: "down the track" is a prepositional phrase. All prepositional phrases have no verbs nor subjects. These can be used as adjectives or adverbs. They can be placed either after the verb and at the begining of a sentence. When placed at the beginning of a sentence, it sounds more formal than the common structure composed of 'subject + verb + predicate' and this construction has to be followed by a comma.
In this case, the answer would be:
'Down the track, the motorcycles raced for the prize'.
I believe the answer is C. You can brake that sentence into to two sentences and it will flow better.
Hope that helps! :)
<span>A longer sentence structure can give a reader the feeling that the pace is slowing down. Heavily-detailed sentences and paragraphs can make time feel as if it is standing still. Shorter sentences without detail can make time seem as if it is flying by instead of slowly progressing.</span>
