Answer: Change the underline words to these! If there is an added punctuation, add that too!
1. Yourself
2. Comma (,)
3. Whom
4. Who
Explanation:
1. oneself doesn’t make sense, instead use “yourself”
2. The comma is used to create a pause which feels needed there
3. Who could become whom as this is appropriate here
4. Whom isn’t appropriate. Yet, Who is!
