Question

years into the flint, michigan water crisis, state officials continued to insist that the city’s tap water met federal safety standards. when independent teams from virginia tech and local hospitals released data showing lead levels many times higher than allowable limits, their findings _____ those official assurances.

3 mark for review
which choice completes the text with the most logical and precise word or phrase?
a corroborated
b disputed
c qualified
d summarized

Explanation:

To solve this, we analyze the context: state officials said water was safe, but independent teams found lead levels far above limits. So the findings should go against the official assurances.

• Option A "corroborated" means to support, which is opposite of what's needed.
• Option B "disputed" means to challenge or disagree with, which fits as the data contradicts the officials' claims.
• Option C "qualified" means to modify or limit, which doesn't fit here.
• Option D "summarized" means to give a summary, which is irrelevant.

Answer:

B. disputed
