I am confused why the compound noun has the singular verb "HAS" in the modifier clause "which has won awards..." and the plural verb "HAVE" as the main verb.
Should I use plural or singular verb as the verb in the main and modifier clause?
A national supermarket chain and a locally owned bakery, which HAS won awards for its crosissants, HAVE seen a significant decrease in the revenue since the biggest employer in the area shut down.
