Answer 2

1. He nearly failed the exam. (Correct)
2. My friend can cook Chinese very well. (Correct)
3. You can't be serious about quitting your job. (Correct)
4. Lately I have had trouble concentrating. (Correct)

Explanation:

1. "Nearly" and "near" are both correct in this context. However, "nearly" is more commonly used to mean "almost" or "very close to," so it is the preferred option here.
2. "Very well" is the correct phrase to describe someone's ability to cook Chinese food. "Very good" would be more appropriate when describing the quality of the food itself.
3. "You can't be serious" is the correct phrase to express disbelief or doubt. Adding "seriously" would not be grammatically correct in this context.
4. "Lately" is the correct adverb to describe a recent period of time. Therefore, "Lately I have had trouble concentrating" is the correct sentence.
