“My favorite place to study is under this tree,” But suddenly the wind blew. 

"My favorite place to study is under this tree," but suddenly the wind blew.

Adding period after the word "tree" and capitalizing the word "But" will make it two separate sentences. This change is necessary because "But suddenly the wind blew" is an independent clause that cannot be directly joined to the previous sentence without a proper conjunction or punctuation mark.

“Are you sure we can study here?”

"Are you sure we can study here?"

The grammar in this sentence is correct. It's a direct question, and the subject "you" follows the helping verb "are" and followed by the main verb "study." The word order and punctuation are appropriate for asking a question in English.

The following day, the teacher brough George to a courtyard. But it was too bright there.

The following day, the teacher brought George to a courtyard, but it was too bright there.

I corrected the grammar by changing "brough" to "brought," and I added a comma after "courtyard" to properly connect the two independent clauses. "Brought" is the past tense of the verb "bring," which is the correct form to use in this context. I added a comma before "but" to create a compound sentence. This comma helps separate the two related but independent clauses, making the sentence more clear and easier to understand.
