Answer

The work done during the last meter of the stretch is greater.

Work Step by Step

Recall, work is equal to the area under the force versus distance graph. Thus, since the force versus distance graph is approximately linear and goes through the origin, we find that there is far more area under the graph during the last meter than during the first meter. Thus, the work done during the last meter of the stretch is greater.
