Final answer:
The expression "the sweating gangs" typically implies that the individuals are hardworking and engaging in physically laborious activities. Choice B is the most accurate interpretation.
Step-by-step explanation:
The use of the expression "the sweating gangs" suggests that its members are involved in hard, physically demanding labor that causes them to sweat profusely. It does not give a direct insight into whether they enjoy this labor or not, but it does convey a sense of vigorous exertion. The closest choice to this implication is B) The expression implies that the members are hardworking and laboring vigorously. It is likely describing individuals who are intensely engaged in their tasks, which requires a significant amount of effort and physical work, hence the sweating. However, without additional context, it's not clear whether this work is voluntary and fulfilling or forced and oppressive.
