Passage Summary: A president's job is to look out for the people who own the company. Because of this, the president must make sure the company makes a lot of money.

Conclusion: Corporate presidents have a duty to maintain high profits.

Reasoning: Presidents are required to promote the key interests of the company's shareholders.

Analysis: The argument assumes a connection between 'shareholder interests' and 'high profits.' While this might seem like common sense in the real world, on the LSAT, it's a logical gap that needs to be bridged. To strengthen this, look for an answer that explicitly states that high profits are indeed a key interest of shareholders. We want to turn that 'Therefore' into a solid, unbreakable link by confirming that the goal mentioned in the premise is achieved by the action mentioned in the conclusion.
