What is implied about the success of the scheme?

The implication of the success of the scheme being that it is doomed to failure suggests a pessimistic view regarding its execution or effectiveness. This choice conveys a strong negative outlook, possibly indicating that previous attempts have not yielded positive results, or there are significant flaws in the design or implementation of the scheme that would lead to its ultimate failure. Such implications may stem from contextual cues within the surrounding text or a consistent history of unsuccessful outcomes related to the scheme.

In contrast, the other choices provide alternatives that do not align with this negative implication. The first option, for instance, indicates a positive outlook, while the second option reflects disinterest rather than a judgment on success. The fourth option suggests a need for improvement but does not definitively indicate failure. Thus, the choice that correctly captures a clear implication about the scheme's success is that it is doomed to failure.
