Question

read the passage.
(1) ask young people today if they know of anyone who has had smallpox, and they might ask, \whats smallpox?\ (2) that is because this disease was eradicated from the planet decades ago, thanks to vaccinations. (3) despite the obvious effectiveness of vaccination, opponents of this procedure argue that humans are better off fighting diseases on their own without adding anything potentially harmful to their bodies. (4) still, the american academy of pediatrics says that vaccines can be 99 percent effective, and the centers for disease control claims that, over a 10-year period, vaccines allowed 322 million children to avoid illnesses. (5) so the next time someone tells you that vaccines are poisoned apples that will lead to a fate like snow whites, counter their argument with the facts. (6) the bottom line is that vaccines are safe to use and save lives.
how can the writer add parallelism in this passage?
○ by changing the phrase \young people\ to \most people\ in sentence 1
○ by deleting the words obvious and potentially from sentence 3
○ by deleting \save lives\ and adding the phrase \easy to administer\ to the end of sentence 6
○ by shortening the passage to only five sentences by removing sentence 5

Explanation:

Parallelism requires matching grammatical structures in phrases. Sentence 6 currently has "safe to use" (adjective + infinitive) and "save lives" (verb + object), which are not parallel. Changing it to "safe to use and easy to administer" creates two matching adjective + infinitive phrases, achieving parallelism. The other options do not address parallel structure: changing "young people" alters audience focus, deleting adjectives does not fix structure, and shortening the passage removes content without fixing parallelism.

Answer:

by deleting "save lives" and adding the phrase "easy to administer" to the end of sentence 6
