Rina hustled through the classroom door, found her assigned seat, and sat down. After a few greetings to her friends, she unzipped her bulging binder and began to sort through its pages. She unearthed dog-eared worksheets, highlighted notes, and dated projects; alas, last night's homework was not in the World History section where she had hoped it would be. As the bell rang, Rina's fruitless search continued.

Based on the evidence provided, readers can conclude that Rina is

a) unconcerned.

b) studious.

c) ambitious.

d) disorganized.

d) disorganized

Evidence:

Rina has a bulging binder, which implies that she does not take the time to organise her folder.

Rina has to sort through her pages, implying that they are uncategorized and it is hard to find certain sheets.

Rina's pages are 'dog-eared', which means that the corners are folded untidily.

Rina has dated projects which indicates that she has unfinished tasks in her binder.

The fact that she is rushing to find her homework from last night indicates that Rina had done her homework after procrastinating.

Rina cannot locate her homework in the rightful section of her binder and has failed to locate her homework (the search was 'fruitless', meaning that nothing had been found).

I would say the answer is D) disorganized
