Question

select the evidence that the author provides for the following supporting claim: a period following a text can convey insincerity.
students thought that one - word replies were more sincere.
students thought that handwritten notes were more sincere than text messages.
students thought that text replies that didnt contain punctuation were more sincere.

Explanation:

The claim is that a period in a text can convey insincerity. We need evidence that links lack of punctuation (or presence of punctuation affecting sincerity perception) to higher perceived sincerity, which supports that punctuation (like a period) would lower it. The third option states that text replies without punctuation were seen as more sincere, which directly supports the claim that a period (a type of punctuation) would make a text seem insincere.

Answer:

Students thought that text replies that didn't contain punctuation were more sincere.
