Hi,
since the 1920s and since 1920 are both valid. I have seen similar usage in a GMAT Prep SC question. So, that is enough to say it is accepted by GMAC. However, I have other doubts in this question. Is this from an authentic source or pasted from an article? I have googled this and found the following:

I am confused about the usage because plural verb 'have' in this source. It doesn't agree with the subject family, which I believe is singular as it is a collective noun.

No need . The OA is C . The Explanation is that B changes the original meaning

I am not worried about the underlined part. Of course, B changes the meaning. I have posted him regarding the usage of 'their'. I am not too sure about it.

Edit: I am clear about the usage of 'their'. So, requested him not to respond.

I am confused about the usage because plural verb 'have'. It doesn't agree with the subject family, which I believe is singular as it is a collective noun. Can 'family' be plural as well? Similarly, the non-underlined portion has their. I don't think it can refer to artists. I guess it can only refer to family, which is again singular.

Expert opinions are appreciated!

Hi,

I thought 1920 better than 1920s, however, since you mentioned that you have seen similar usage in GMATPrep - could you pls share some more insight into such usage. How 1920 and 1920s are different/same and how B and C changes the meaning.

regarding 'their' - IMO their, a pronoun, can refer to a noun inside a prepositional phrase ie artists here

Hi,
Original sentence says since the 1920s, which is a valid usage. So, we should preserve the meaning of it. 1920s means some unclear time between 1920-1930(more or less encapsulating the decade. it could be 1921,1922...so on). In B, usage of 1920 means you are making it strictly year of 1920(specific). That is what I mean by change in meaning. C doesn't change meaning. It corrects the verb have to has(singular).

Yup, even I feel the same. But, I was not 100% sure so just wanted someone to confirm this because I regularly see constructions such as 'a group of players showing their skills'. I just wanted a confirmation of this. Now that I feel it is valid, I will edit that part so that others don't get confused.
