I think the question is asking which sentences include misspelled words.
It's sentences 2 and 4 and the misspelled words are:
"success" and "environment" in sentence 2: they are misspelled in the original text.
"cold-weather gear" and "chose" in question 4
Additionally "anxious" is misspelled in question 3.
