Answer: Some are wrong
Explanation: Look at the sentence “I think that everyone of us must rely on himself and do his best to get a job that doesn’t make him turn to others”
The mistake here is : “himself, his, doesn’t and him” since you used “everyone of us” as the subject you should also followed up by the same ones as well. So it should be “ourselves, our, don’t and us”
And appourtunities isn’t spell like that
It’s spelled: “opportunities”
