Self-study
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. ████ ██ ████ ███ █████████ ████ ████ █████ ███████ ███ █████████ ███ ███ ██████████████ ██ ████ █████ ███ ████ █████ ████████ ██ █████████ ████ ████████ ███████ ███ ████ ██████ ██████ █ ███████
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.

If all of the statements █████ ███ █████ ████ █████ ███ ██ ███ █████████ ██████ ██ █████
a
Some leaders who ████████ █████ █████████ ██ ███ █████████ ██ █████ ███████ ██ █████████ █ ████ █████ █████████████ ██ ████ ████ ██ ███ ██████████ ██ ████ █████
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 ██ █████████ ██ █████ █████████ ███ ████████████ ███████ █████ ███████ ███ ███ ██████████ ██ █ ██████████ ████ ████████ ██ ███████ █████ ██████ ██ ████ █████
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 ██ █ ██████ ████ ███ ████████ ██████ ██ ███ █████████ ██ █████ ███████ ███ ███ ██████████ ██ █ ██████████ █████
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 ██ █████████ █ ██████████ ████ ███████ ████ ██████ ████ █████████ ████ ██ ██████ ██ ██ ██ ████ █████ ████████
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 ██████ ██████ ██ ███████ █████ ███████ ███ ██████ ███ ███ ██████████ ██ █ ██████████ ████ ████████████ ██████ █ ███████
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.
