The importance of using a variety of sentence structures is to change up your writing. To make the reader engaged in what you have to say. If your sentence structure is weak and does not vary the reader might get bored. It also better shows your topic.

<span>The correct option is B. Mike joined the Army, and he became more disciplined during the training. The correct way to connect these two clauses is to introduce a conjunction "and." A is incorrect because there should be a comma/conjunction between the words Army and he. C is incorrect because that semi colon is just randomly and incorrectly placed without a context. D is incorrect because there should also be the word "and" before "he."</span>
Its C because the scientist ended what he had to say
