The subject in this part of the sentence is „better running with the cops“. Here`s the „best game“ theme, while „running with the cops“ is a prepositioning that changes the best part. As „part“ is singular, the subject is actually singular and should be accompanied by a singular verb, „is“, not „are“. „Your bad attitude towards studies“ is the subject of this sentence, so the verb must correspond to the singular theme of the attitude. Therefore, the right verb should be „done“ – their attitude „does not suggest“. The problem with the sentence as it is written is that the theme of the phrase „every night“ is singular, but the verb „were“ is plural. It is your turn to read the rules of the subject-verb agreement. Then read the paragraph that contains errors of agreement. .
