Question 1) The answer is A. The description of the mother’s love as “a river” coveys its abundance, and the mentioning that that it’s “inside me still” suggests that it’s never ending. This is especially clear when compared with B and C, neither of which fit the sentence as much as A.
Question 2) The answer is C. The sentence compared the usefulness of the assembly instructions to a camel in the Arctic. A camel, obviously, would not fare very well in a climate like the Arctic. The answer A is possible, but there is nothing in the sentence that suggests that the instructions were specifically not in English. Therefore, it can be most logically inferred that the instructions were not very helpful.
