The startup's rapid growth proved _______ when a series of management scandals and product failures caused investors to withdraw their support, leading to bankruptcy within two years.
Which choice completes the text with the most logical and precise word or phrase?
beneficial
permanent
sustainable
illusory
Correct Answer: D
Choice D is the best answer. The passage describes rapid growth followed by bankruptcy, indicating the success was deceptive or not real. "Illusory" means based on illusion or not real, fitting this false appearance of success.
Choice A is incorrect because "beneficial" contradicts bankruptcy. Choice B is incorrect because "permanent" contradicts two-year collapse. Choice C is incorrect because "sustainable" contradicts failure.
