To make a question in the Past Tense in English we normally put the auxiliary DID at the beginning of the question or before the main subject. DID is used with regular AND irregular verbs in English. Both Do and Does in present tense questions become Did in past tense questions. In order for a sentence to be grammatically correct, the subject and verb must both be singular or plural. In other words, the subject and verb must agree with one another in their tense
I'm pretty sure the highlighted phrase should be "like fraternities and sororities" because it adds unnecessary details, possibly leaving out ones which are more important.
