Leadership depends as much on making one’s followers aware of their own importance as it does on conveying a vivid image of a collective goal. Only if they are convinced both that their efforts are necessary for the accomplishment of this goal, and that these efforts, if expended, will actually achieve it, will people follow a leader.

Summary
The stimulus can be diagrammed as follows:

Notable Valid Inferences
If people are following a leader, they are convinced that their efforts are necessary for the accomplishment.

If people are following a leader, they are convinced that their efforts will actually achieve the accomplishment.

A
Some leaders who convince their followers of the necessity of their efforts in achieving a goal fail, nevertheless, to lead them to the attainment of that goal.
This could be true. What matters is that people are convinced that their efforts will achieve the goal, not whether or not the goal is actually achieved.
B
One who succeeds in conveying to one’s followers the relationship between their efforts and the attainment of a collective goal succeeds in leading these people to this goal.
This could be true. (B) tells us that if we succeed in conveying the relationship between people’s efforts and attainment of the goal, then we will succeed in leading them to the goal. Like for (A), nothing in the stimulus contradicts any claims about actually achieving goals.
C
Only if one is a leader must one convince people of the necessity of their efforts for the attainment of a collective goal.
Could be true. (C) says that if you convince people of the necessity of their efforts, then you are a leader. The stimulus gives necessary conditions for when leaders are followed; (C) gives a sufficient condition for being a leader, which isn’t inconsistent with the stimulus.
D
Sometimes people succeed in achieving a collective goal without ever having been convinced that by trying to do so they would succeed.
This could be true. The stimulus gives two necessary conditions for following a leader; the information in (D) that people can succeed without having been convinced that they could succeed is independent of the information in the stimulus.
E
Sometimes people who remain unsure of whether their efforts are needed for the attainment of a collective goal nevertheless follow a leader.
This must be false. As shown below, (E) meets the sufficient condition of “follow leader” but fails the necessary condition of “efforts necessary,” which contradicts the stimulus.
