The best revision for sentence 6 is,The following list contains suggestions for what to include in the chest:
Answer: Option D.
Explanation:
While revising any sentence, we have to make sure that the alteration conveys the same information without changing its meaning. The best possible revision for the given sentence would be, 'The following list contains suggestions for what to include in the chest:' Here we can see the revision conveys the same message as it was before.
The other mentioned option such as A and B couldn't be the best revision mainly because rather than suggesting, those sentences are stating the list. Similarly, option C starts with a first person singular pronoun, which lessens the possibility of best revision.
