Explanation
Correct answer: C.
Choice C is the best answer because it most effectively uses a quotation from "The Mountain" to illustrate the claim that the speaker feels protected by the mountain. In the quotation, the speaker recounts that the mountain felt like a wall that offers shelter from the wind. That the speaker felt sheltered by the mountain suggests that it offered the speaker a sense of being protected.
Why the other choices are wrong
Choice A
Choice A is incorrect because this quotation doesn’t express the speaker’s feeling of being protected by the mountain. Instead, it notes that the speaker has seen a dry ravine and a pasture.
Choice B
Choice B is incorrect because this quotation doesn’t express the speaker’s feeling of being protected by the mountain. Instead, it simply states that there is a mountain, which is meant to be viewed.
Choice D
Choice D is incorrect because this quotation doesn’t express the speaker’s feeling of being protected by the mountain. Instead, it indicates that the speaker has gone around the mountain.
