✔ Explanation:

The main issue in this exercise is capitalization. Only two sentences had errors:
- Sentence 2: "A" was lowercase.
- Sentence 6: "a" was lowercase.

All other sentences are grammatically correct and properly punctuated. The task is likely aimed at teaching students to recognize and fix capitalization rules — specifically that the first word of every sentence must be capitalized.
