Assure could mean making sure something happens, to comfort or remove doubts from a person, or make someone sure of something.
If it's one word answers it could be persuading, guaranteeing, promising, convincing, reassure, satisfy, or tell.
I hope this helps without answer choices it's kind of hard to know what kind of answer you need. Have a great day!
Well number six you should take the comma out between complaint and demanding
"it" is the subject. because it comes before the verb and there is no other subject after the verb.
