Answer:
Annie and her brothers ARE at school
Explanation:
The word that correctly completes the sentence is "are" and this is simply because of the rules of concord in English grammar.
The subject-verb agreement means that if the subject is in plural, then the verb must also be in plural.
The subject "Annie and her brothers" is in plural form, therefore the verb "are" must be in plural.
Based on the given sentences above, the one that is punctuated correctly is the second sentence: She sends an email therefore, to her instructor and advisor. What makes the first sentence incorrect is that, it has no period at the end of the sentence. Hope this answer helps.
