In 2018, cognitive biologist Dr. Alex Taylor conducted experiments with New Caledonian crows. He found that the birds could solve complex multi-step puzzles to access food and could remember the solutions months later. This finding _______ the common belief that birds lack the intelligence to perform higher-order problem solving.
Which choice completes the text with the most logical and precise word or phrase?
dispelled
confirmed
evaded
processed
Correct Answer: A
Choice A is the best answer. The text explains that crows can solve complex puzzles. This evidence contradicts the "common belief" that they lack intelligence. "Dispelled" means to make a doubt, feeling, or belief disappear.
Choice B is incorrect because "confirmed" would mean the crows were indeed unintelligent. Choice C is incorrect because "evaded" means avoided. Choice D is incorrect because "processed" means dealt with.
