Hospitals, universities, labor unions, and other institutions may well have public purposes and be quite successful at achieving them even though each of their individual staff members does what he or she does only for selfish reasons.
Facts
Even though individual staff members at hospitals, universities, and other institutions are doing what they do for selfish reasons, they end up successfully achieving public purposes.
Evaluate
This is an Inference task (the paragraph is supposed to support the answer). When we're doing Most Supported and we see a Pivot word, such as but / yet / however / even though, the correct answer is usually a safely worded claim that Straddles the Pivot.
Goal
Look for a safely worded claim that reconciles "acting for selfish reasons" with "successfully achieves public purposes".
