The correct answer is A, "solved". This is because the sentence structure implies that the act of lending money will result in the resolution of the problems. The verb "solve" is appropriate here as it means to find an answer to or a way out of a problem. The other options do not fit the context: "caused" would imply that the lending of money would create problems, which contradicts the positive outcome suggested by the sentence; "covered" generally means to hide or protect, which does not align with the idea of resolving issues; and "met" suggests an encounter or coming together, which does not convey the sense of a problem being addressed or resolved. Therefore, "solved" is the correct choice as it directly relates to the idea that the problems will be resolved if the money is lent.
