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:

The words "about" and "approximately" both convey an approximate quantity. Using both is redundant.

Answer:

Either "about" or "approximately" can be removed. For example, removing "about" gives "The Centers for Disease Control and Prevention estimates that approximately one in six Americans gets sick with foodborne illnesses each year." Removing "approximately" gives "The Centers for Disease Control and Prevention estimates that about one in six Americans gets sick with foodborne illnesses each year."
