A researcher conducted an experiment inspired by studies suggesting that people may benefit from feeling frightened

Choice A is the best answer. This choice illustrates both “feeling frightened in controlled situations” (the haunted house) and the benefit of a boosted mood (“less stressed”) and confidence (“very accomplished”).

Choice B is incorrect. This choice isn’t the best illustration of the claim. While laughing may indie a good mood, this choice provides no evidence of “feeling frightened” or boosted confidence. Another choice provides better evidence. Choice C is incorrect. This choice isn’t the best illustration of the claim. This choice demonstrates “feeling frightened” in a controlled environment, but it doesn’t provide strong evidence of boosted mood or confidence. Another choice provides better evidence. Choice D is incorrect. This choice isn’t the best illustration of the claim. While a “sense of relief” could be interpreted as a boosted mood, this choice doesn’t provide direct evidence of “feeling frightened” or of increased confidence. This choice simply suggests that haunted houses and scary movies have a similar effect. Another choice provides better evidence for the researcher’s claim.
