Explanation:

• Analyze each option:
• Option 1: The text doesn't show Isabella thinks the mystery is too complicated. She stops asking questions not because of complexity, but maybe for family happiness. Eliminate.
• Option 2: There's no info suggesting she believes nothing happened between dad and Allison. The focus is on her decision to not probe, not her belief about the past event's existence. Eliminate.
• Option 3: In paragraph 31, she was ready to ask hard - hitting questions, but in 32, she sees dad and Allison happy and Grandpa grinning. She decides to let them be happy instead of uncovering the past. This matches.
• Option 4: The text has no content related to her losing interest in journalism. Eliminate.

Answer:

She would prefer to let her dad and Allison be happy than to uncover their past.
