Question

nan gao and her team conducted multiple surveys to determine participants’ levels of comfort in a room where the temperature was regulated by a commercial climate control system. participants filled out surveys several times a day to indicate their level of comfort on a scale from -3 (very cold) to +3 (very hot), with 0 indicating neutral (neither warm nor cool), and to indicate how they would prefer the temperature to be adjusted. the table shows three participants’ responses in one of the surveys. according to the table, all three participants wanted the room to be cooler, ______. which choice most effectively uses data from the table to complete the statement? choose 1 answer:
a) and they each reported the same level of comfort.

b) even though each participant’s ratings varied throughout the day.

c) but participant 20 reported feeling significantly colder than the other two participants did.

d) but participant 1 reported feeling warmer than the other two participants did.

Explanation:

To solve this, we analyze each option:

• Option A: The table (from the context of the survey) likely shows different comfort levels (since the options imply variation), so they don't all have the same comfort level. Eliminate A.
• Option B: The statement is about the data in one survey, not about variation throughout the day. The question is about the data in "one of the surveys", so B is irrelevant. Eliminate B.
• Option C: If all want the room cooler, a participant feeling "significantly colder" would likely want it warmer, not cooler. So C contradicts the "all wanted cooler" premise. Eliminate C.
• Option D: If participant 1 reported feeling warmer (higher on the -3 to +3 scale, e.g., closer to +3 or higher than the others), they would still want the room cooler (since even warm people can want cooler), and the others (feeling less warm or colder) also want cooler. This fits.

Answer:

D. but participant 1 reported feeling warmer than the other two participants did.
