Explanation:

The first sentence contains the word effect which is incorrect. Instead, it should be affect.

The second sentence has a misplaced punctuation mark. After the words mad at him at the end of the sentence wit the misplaced punctuation mark, there's a period which shouldn't have been there. With this misplaced punctuation mark, the sentence is a fragment or an incomplete sentence. Instead, the period should be removed and the If should be in common letters as well.

The last sentence has a error as well as it has the wrong word. The word should've been to and not too.
