Explanation:

First Question (Which best expresses the main idea of this passage?)

• Option A: The passage doesn't focus on the cause of food contamination being microbial infection. It's about ways to avoid contamination, not the cause.
• Option B: The passage isn't about refrigerating food to avoid contamination. The content is about various precautions like handwashing, not leaving cut produce out, etc.
• Option C: The passage lists multiple ways food can be contaminated (slicing on cutting board, leaving cut produce out, not washing hands, changing diaper while preparing food) so this option fits as it says food can be contaminated in many ways.
• Option D: The passage doesn't mention cooking food thoroughly. It's about other precautions.

• Option A: This line is about unpasteurized fruit juice contamination, which is a specific example, not the main idea.
• Option B: This line states that there are many opportunities for food to be contaminated during production and preparation, which aligns with the main idea that food can be contaminated in many ways (as seen in the passage's content about various precautions to avoid contamination).
• Option C: This line is about outbreaks traced to fresh produce, a specific example, not the main idea.
