Hi the following question is a 4 part question, I did the first part so I just need confirmation that it was correct and then I need help with parts 2-4 as I am somewhat confused. Thank you in advance!

P.S for 3-C the options are as follows

equals, greater than or less than

will or will not

should or should not

Thanks!
