Leo: Given the sentence "Two young ladies with red-hair are sitting on a bench and talking to a third young lady with black hair." is it true that "A group of girls sitting and talking."?
Mei: OK, So, let's think first...
Me:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

Two young ladies sitting and talking to a third young lady are by inference also a group of girls sitting and talking.
Thus, the answer is yes.
