The corporation's public commitment to environmental sustainability was undermined by internal documents revealing executives had _______ policies that would have effectively addressed their carbon footprint.
Which choice completes the text with the most logical and precise word or phrase?
embraced
promoted
blocked
celebrated
Correct Answer: C
Choice C is the best answer. The passage describes a contradiction between public commitment and internal actions that "undermined" sustainability. "Blocked" means to obstruct, fitting this prevention of effective policies.
Choice A is incorrect because "embraced" would support, not undermine. Choice B is incorrect because "promoted" contradicts undermining. Choice D is incorrect because "celebrated" contradicts the contradiction.
