Come up with a question and reasoning that would justify [21] as the answer.
The question is: Sami finds 3 spiders in the playground. Hunter sees 12 ants climbing the wall. Ming discovers 8 ladybugs in the sandbox, and watches 2 of them fly away. How many insects are remaining in the playground?
Reasoning: The children find 3 + 12 + 8 = 23 insects. After the ladybugs fly away, there are 23 - 2 = 21 insects.

Come up with a question and reasoning that would justify [1] as the answer.
The question is: A store received 20 pallets of paper products to stock. Half the pallets were paper towels, a quarter were tissues, and a fifth were paper plates. The rest were paper cups. How many pallets of paper cups did the store receive?
Reasoning: The store received 20 / 2 = 10 pallets of paper towels. They received 20 / 4 = 5 pallets of tissues. They received 20 / 5 = 4 pallets of paper plates. Thus, the store received 20 - 10 - 5 - 4 = 1 pallet of paper cups.

Come up with a question and reasoning that would justify [32] as the answer.
The question is: Harvey and his friend Sam decided to run a footrace in their school track field to see who was better at running. While at it, Harvey runs 8 miles more than his friend Sam, who runs a total of 12 miles. Calculate the total number of miles the two friends run together.
Reasoning: If Harvey ran 8 more miles, then he ran a total of 12 miles + 8 miles = 20 miles. The two friends ran a total of 20 miles + 12 miles = 32 miles.
