Subject-verb agreement happens in the simple present tense when the subject is a third person (a He, a She, or an It) and the verb is added an S, an ES, or IES to the ending of such verb, for example:
My Father works in a Bank. Subject + VerbS
In this case the verb is added an S because the subject “my father” is a “HE” and by having that done, there is a subject-verb agreement.
Joy study really hard every time she has exams. Subject + Verb
In this case the verb has no change even though the subject is a SHE, in this case there IS NOT subject-verb agreement for the verb stays with no change when there must be one.

A) Every one of the applicants appear prepared.

B) All of the team members is highly qualified. the subject is plural and the is for the third person.
