GMATNinjaI have come across two official problems that treat the descriptor of a noun at the beginning of the sentence being offset by a comma or no comma differently.
In this problem, there is a comma --> "Architects and stonemasons, the Maya".
In number 868 in the Official Guide 2020 version, there is no comma--> "Jazz pianist and composer Thelonious Monk produced..."
How should I go about this?
Thank you
