Answer 1

The correct choice to complete the statement effectively using data from the table is:

(Choice C) but participant 20 reported feeling significantly colder than the other two participants did.

This choice is supported by the data provided in the table, where participant 20 has a comfort rating of \[-2\], indicating they felt colder than participants 1 and 21, who both reported a comfort rating of \[1\]. This highlights the difference in comfort levels among the participants while still noting that they all wanted the temperature to be cooler.
