Question

select the word or phrase that is redundant and can be removed without changing the meaning of the text. the centers for disease control and prevention estimates that about approximately one in six americans gets sick with foodborne illnesses each year.

Explanation:

In the sentence, "about" and "approximately" have similar meanings (both convey an approximation). So one of them is redundant. We need to identify which one can be removed. Since both are adverbs indicating approximation, either could be redundant, but in this case, we look at the options (though the options aren't listed here, the redundant phrase is either "about" or "approximately". From the sentence, "about approximately" are redundant, so we can remove one. The redundant phrase here is "about" or "approximately" (more likely "approximately" or "about"—in this case, the redundant one is either, but in the sentence, "about" and "approximately" are both used, so one can be removed. The redundant word/phrase is "about" or "approximately" (let's say "approximately" or "about"—the correct redundant one is either, but in the sentence, "about" and "approximately" are redundant, so we can remove one. So the redundant phrase is "about" or "approximately" (for example, "approximately" can be removed, or "about").

Answer:

The redundant word or phrase is "about" (or "approximately"—either can be removed as they are redundant). If we have to choose, "approximately" (or "about") is redundant. So the answer is "about" (or "approximately").
