Question

for most of my life, i did not understand what it meant to be a part of a team. i was training for the chicago marathon, and the long miles were difficult to complete, so i joined a running club. the members’ enthusiasm for running made the miles easier. when the big day arrived, we got together and ran the first few miles as a group, but then we lost one another in the crowd. at mile 20, one of my teammates came up behind me, and we finished the race together. sharing encouragement helped us to meet our goal of becoming marathoners. teamwork works! what type of phrase is \for running\? adjectival phrase what word does \for running\ modify? enthusiasm what does \for running\ add to the text? it conveys time or location. it adds detail and precision. it provides interest and variety.

Explanation:

To determine what "for running" adds, analyze the phrase. It modifies "enthusiasm" by specifying the type of enthusiasm (for running), which adds detail and precision about the enthusiasm. The other options are incorrect: it does not convey time/location, nor is its main role to provide interest/variety.

Answer:

It adds detail and precision.
