What did Abel do for the speaker?

The choice indicating that Abel cut the speaker's grass is correct because it implies an action performed by Abel that is tangible and specific. Cutting grass is a direct and practical task, suggesting that Abel was helpful in a way that addressed the speaker's needs or requests. This act may symbolize support or assistance within their relationship, reinforcing the notion of someone taking care of a chore or responsibility.

In contrast, other options present actions that either do not directly address a practical need (like providing advice or giving a speech) or imply a negative action (ignoring the request), which does not align with the context of someone being helpful or supportive. Therefore, the action of cutting grass stands out as a concrete example of Abel's contribution to the speaker's situation.
