Which phrase indicates that someone is expressing a desire to leave a group?

The phrase "Given the hint that he no longer wishes" suggests a desire to withdraw from or leave a group. It implies that the individual is signaling a lack of interest in remaining part of the group, which is a clear indication of wanting to exit. The use of "no longer wishes" conveys a shift in intention, marking a departure from previous engagement or participation.

In contrast, the other phrases do not carry the same connotation of wanting to leave. "Encouraged to stay in the group" indicates a positive reinforcement to remain involved. "Expressing strong commitment" suggests a dedication to the group, which is the opposite of wanting to leave. Finally, "Hoping to take a leadership role" implies an aspiration to be more involved and influential within the group, rather than exiting it. Therefore, the first phrase is the only one that clearly aligns with the idea of wanting to leave a group.
