If one enjoys the benefits of a group's collective efforts but did not contribute to those efforts, one is called a a. political activist b. citizen c. lobbyist d. free rider e. subject

The answer is option "d. free rider".

Groups with lower MPCR had altogether more free riding. Then again, a higher MPCR prompted higher gathering commitments. The impact of gathering size, however, is indeterminate. In the event that the size is expanded with steady MPCR, more gathering commitments happen, in light of the fact that the aggregate asset accessible to the gathering is expanded. Yet, in the event that the MPCR is brought down together with an expansion in aggregate size, bring down gathering commitments and all the more free riding is watched. We can tell from these outcomes that MPCR, and additionally add up to asset in the gathering, is imperative in deciding gathering commitments.

The answer would be limited.

Low risk and moderate growth.
