What can be inferred about the new student based on the woman's description?

The inference that the new student is shy arises from the woman's description, which likely highlights characteristics or behaviors typically associated with shyness. For instance, if the woman mentioned that the new student tends to keep to herself, avoids large groups, or appears nervous or hesitant in social situations, these attributes would strongly indicate shyness. This understanding reflects the general association between specific behaviors and personality traits, allowing one to conclude that the new student might be more reserved and less likely to engage actively in conversations or social interactions.

In contrast, the other options suggest different personality traits that would not align with a shy disposition. For example, if the student were outgoing or very talkative, one would expect descriptions that include active participation in conversations, enthusiasm for meeting new people, or a tendency to express thoughts freely. Lastly, being described as popular implies a certain level of social adeptness and acceptance among peers, which typically contradicts the traits commonly associated with shyness. Therefore, the description more accurately supports the inference of shyness over the other traits.
