Me with this the one i chose is incorrect soo me !

I believe the answer is B.

i believe the answer is additional classes. that is because if you didn't learn it in school, most likely you would have to take a class at college about this subject.

i will have to go with 1.

hope this !

either online or traditional classroom can work for students. which is better will depend on students and teacher. students may have trouble following a lesson in classroom while they can study at their own pace online. other students may have trouble staying focus on their own in online classes. teachers are more used to classroom teaching but they may also be more worry about their jobs teaching online classes and work harder.
