In this task, you need to write an incorrect answer to the given question. Along with the question, you are also given the correct answer(s) and the associated paragraph. An incorrect answer should be closely related to the content of the paragraph and/or the question but will not truthfully answer the question. Your incorrect answers should be similar to the given correct answer such that it will pose a challenge for students to distinguish the two. A good incorrect answer should prevent those who skip the paragraph from answering the question. The incorrect answer should not be trivial, in the sense that they should not be easily eliminated without reading the paragraph.
One example: Paragraph- Sent 1: It was hot that day.
Sent 2: The temperature on the wall of the backyard was showing something well over 100 F.
Sent 3: Meanwhile Tom, at home, was trying finish the remainder of carrots from last night, and packing for his trip to Chicago tomorrow.
Sent 4: As employees of the Art Museum, Tom and his older cousin often had to travel to Chicago. Question: What was the temperature outside, when Tom was eating carrots? Correct Answer: well over 100 F.
Solution is here: Not very hot.
Explanation: This is a good incorrect answer, as most of the the words of this answer appear in the the paragraph. They are also related to the content of the question (temperature), yet do not answer the question correctly. Consequently, one has to carefully read the paragraph understand that "not very hot" does not answer the question.
