The researcher's conclusions were tentative, based on preliminary data that would require much larger studies to confirm. She emphasized the need for further investigation.
As used in the text, what does the word "tentative" most nearly mean?
definitive
incorrect
popular
provisional
Correct Answer: D
Choice D is the best answer. The passage describes conclusions based on "preliminary data" requiring confirmation. "Provisional" means temporary or conditional, fitting conclusions pending further study.
Choice A is incorrect because "definitive" contradicts needing confirmation. Choice B is incorrect because "incorrect" isn't indicated; they're just unconfirmed. Choice C is incorrect because "popular" doesn't relate to certainty level.
