Passage Summary: Because the singer Marian Anderson had a difficult upbringing, she was able to keep a good perspective on life, which proves she didn't take her success for granted.

Conclusion: Marian Anderson did not view her success as something to be taken for granted.

Reasoning: Anderson experienced significant hardships early in her life, and having such early struggles allows a person to maintain a healthy perspective on the world.

Analysis: This argument presents a logical chain: Early Struggle leads to Good Perspective, and Good Perspective leads to Not Taking Success for Granted. However, the second link in that chain is missing from the premises. To make the conclusion follow with absolute certainty, we need a 'bridge' that connects the concept of 'keeping a good perspective' to 'not taking success for granted.' Look for an answer choice that explicitly states that anyone who keeps a good perspective on the world will not take their success for granted.
