Answer:
The following one which is not one of the five basic questions that influence project scope is what is the efficiency of each of the team members.
Explanation:
Because the efficiency of the team members does not mean a sucessful project. Putting a team together is not a priority in the first moment.
Guidelines such as having a basic understanding of what being asked on a production level, setting deadlines, project management, being aware of the great picture, knowing what is out of scope and having tangible goals are the most important things to take care in the first place.
Basicallly, you have to figure it out those five questions, and only then get worried about your team member efficiency. Sometimes you do not have the most qualified team member, however he is the most likely to learn more and be more interested in the project.
