I always assumed that "a pair of shoes" followed in the footsteps of "a pair of scissors" or "a pair of jeans" and have a singular verb when used in a passive sentence. However, one of the English teachers at my school had a conflicting opinion. According to them, it shall accomodate a plural verb as the object is in plural, i.e. "shoes" is plural whereas "jeans" is singular itself. Another teacher had another different explanation, he said that a singular verb is used in writing whereas a plural verb has colloquial usage. So, here I am. Which one is correct and why?
P.S. I think the second teacher's explanation was BS because I have never heard anyone say, "A pair of jeans are a good present for me." or similar phrases.
Edit: Thanks, I got the answer. Basically, depends on context.
