Context: What do I need to improve on ? It 's hard to explain just how strange and foreign birthdays are to me . I 'll try to give you an explanation : Yesterday afternoon , on the bus ride home , I was studying for my French semester final . I was curled up in an awkward position , wedged inbetween my backpack and the window , cradling my textbook in my lap , and mumbling French vocabulary under my breath .

Question: Why might this person have been studying French ?
Options:
0. Because they have an upcoming French test
1. None of the above choices .
2. Because birthdays are strange and foreign to them
3. Because they were cradling their textbook
Answer: 0
