(I don't know if it is entirely appropriate to ask this question here but,) given the following phrases:
- The birthday of family members is... (celebrated based on the lunar calendar)
- The birthdays of family members are...
Is the singular/plural simply a matter of style or, perhaps more technically, on which number sense you want to focus on? Given that the 'family members' is plural in both cases, the reader knows that there must be multiple birthdays involved... not just one, by the virtue of the 'family members' being plural (as a side note, I guess for this case specifically, and not necessarily in general, as the reader would know about the nature of birthdays and family members). So I guess my question is, are those two versions both accurate/correct (and convey pretty much the same meaning)? Which would be the more preferred in general (if there is a kind of a 'definite' answer/ruling for it)? What kind of impressions do you get when you read phrase 1 versus phrase 2?
