Read the passage and answer: When the engineer ran the simulation a third time, the same error appeared. She checked her inputs carefully — all correct. The hardware tests had passed earlier. The problem had to be in the software itself. With a sigh, she began the slow process of reviewing each function in the code. What can be inferred about the engineer?

Behavioral inference: the engineer's actions reveal her character traits. She: ran the simulation three times to confirm the problem; checked her inputs carefully; verified hardware tests; sighed but kept going; began systematic code review. These behaviors indicate: methodical (follows steps), persistent (didn't give up after first failure), careful (verified inputs, checked hardware before assuming software), and willing to do detailed work ('slow process of reviewing each function'). Distractor analysis: 'giving up' — she's continuing despite frustration; 'made the error in inputs' — she checked and they were correct; 'doesn't understand' — her systematic approach indicates competent understanding. Character inference uses actions, dialogue, thoughts, and details to draw conclusions about people. Look for patterns of behavior; what someone does repeatedly tells you who they are.
