Final answer:
The choice that would undermine the argument is (c) The advocates of the solution lack credibility, as it directly jeopardizes the trust in the proposed solution.
Step-by-step explanation:
Among the given options, the one that would undermine the argument is (c) The advocates of the solution lack credibility. This is because if those who propose the solution are not deemed credible, it casts doubt on the validity of the solution itself, regardless of its merits or past successes. Proposals require trustworthy advocates to catalyze adoption and foster confidence in the proposed measures. On the other hand, options such as the solution being successfully implemented elsewhere (a) or alternative approaches having failed in similar situations (b) would serve to support the argument rather than undermine it. Lastly, while option (d) notes that the problem addressed is not as significant as claimed, it does not directly undermine the argument but rather the importance of solving the problem in the first place.
When evaluating proposed solutions to a problem, it is important to understand the historical context, which includes previous proposals and their outcomes. This involves critical questions about why past solutions succeeded or failed and who is responsible for the implementation. It is also necessary to anticipate and address potential objections to the solutions, assessing their necessity and value thoroughly. In doing so, one can enhance the strength and credibility of the proposal.
