The correct answer is A. every day, watches for changes, and dutifully records what happens
Explanation:
In general terms, the purpose for revisions is to improve a sentence, text or paragraph, usually because these have problems in punctuation, spelling, use of transitions, etc. In the text presented, which is about Scientist Experiments, the sentences to be revised are sentence 10 and 11 "She waters the seed every day, watches for changes. And then she dutifully records what happens".
The main issue with these sentences is the use of punctuation as, according to grammar it is not necessary to separate two sentences if the conjunction "and" is being used, instead the period should be replaced by a comma to create a longer sentence. Additionally the use of the word "then" is not necessary as the coordinating conjunction "and" implies one action is linked to the other. Therefore, the best revision is "every day, watches for changes, and dutifully records what happens".
