Maribell had always done well in math and english. but partway through her seventh-grade year, she stopped handing in math homework and spent more time talking during class than listening and working. meanwhile, her grades in english have remained high. which of the following is the most likely explanation for this behavior?
a. she is building friendships with high-achieving peers
b. she has reduced expectations for success in math.
c. she is too busy to study.
d. she no longer cares what her parents and peers think of her.

b. She has reduced expectations for success in math.

Explanation:

It is clear that Maribell is still performing well in English and therefore, she is still interested in education and cares what her parents and peers think. Also, here grades in English are still high and this means that she is still doing her homework and is concentrating on that. But in math class she has not been attentive in class nor has been doing the homework. Hence, the reason is reduced interest or expectation of success in math. Possibly, she feels that math has become too difficult in seventh grade and requires additional support or just some motivation.
