Which of the following is a reason the Marthas are mad at Heather?

• A. Her bag of beets is not good enough
• B. She arrived late to practice
• C. She forgot the posters
• D. She wore mismatched socks

Answer: (A)

The key idea is that the group's anger comes from failing to meet a standard they all expect. The Marthas are upset because the bag of beets Heather brings doesn’t meet that standard—it's not good enough for what they’re trying to do. Their project or plan relies on having acceptable beets, so when Heather’s bag falls short, it triggers their frustration and disappointment.

Other issues like arriving late, forgetting posters, or wearing mismatched socks would create different problems, but in this situation the specific reason for their anger is the beets failing to meet the required quality.
