One way to vary the syntax of the text is to combine sentences since, in this way, your structures will be longer and more complex to follow. This could be done by means of links such as: however, in addition, therefore, etc. When using these words, you create semantic relations between the syntactic structures and make the reading process more difficult because, as I've I said, sentences become longer and therefore the reader has to keep more information in mind to follow the train of thought.
You could also vary the syntax by adding phrases or clauses. This option is similar to the previous one since it also refers to the complexity of the syntactic structures of the text.
ANSWER: A, B, C, D
A includes an adverb of place which is "in World War 1". "World War 1" describes the verb "fight" by stating its location and is thus an adverb of place
B includes an adverb which is "usually". "usually" describes the action/verb "held" by stating how often it was "held"
C, well you know, "carefully".
D should have an adverb too if there isn't any mistake in the sentence as it has the adverb "deeply" which describes the action/verb "worried" by stating the degree of her worrying for George. NOTE: "worried" in this context is NOT an adjective
E does not have an adverb. Although it may seem like "exactly" is the adverb, "exactly" is describing "eight inches long" which is an adjective, not a verb. Therefore, there should be no adverb because the verb in this sentence, which is "said", was not described in any way.
Therefore, the answers are A, B, C and D.
I'm sorry if my answers are wrong and hopefully you can tell me why if it is...
Hope this answer helped :) Also, people should be thinking everyday, or else nothing will have meaning and our daily lives won't be able to function normally. I hope you change your mindset about that, it's really fun to learn on weekends too :)
The last one is your best bet
I believe A is the correct answer
