Doubtful or uncertain; not clearly true, honest, or reliable.
“Critics call the survey's methodology questionable, since only a small sample was used.”
“The report's questionable assumptions have led some experts to reject its conclusions entirely.”
This word flags weak evidence in a viewpoint passage. When you see 'questionable,' expect the author to be criticizing the reliability of a study, statistic, or claim made by the opposing side, which is often tested directly in the comprehension questions.
Synonyms: doubtful, dubious, suspect
