Answer:
Yvonne's level of moodiness is likely to increase because she has higher expectations for academic success than her male peers.
Step-by-step explanation:
When people are maturing at a faster rate compared to other kids on their similar age group, it is very hard for them to blend it to the social groups since they are most likely become bored with what considered to be 'interesting' by their other peers.
Because of this, Yvonne's level of moodiness is likely to increase since she's already focusing about things that would not be in other peer's mind for at least 4 years later. This make her feel lonely and excluded.
