Final answer:
Parlor houses offered a more luxurious setting for wealthier clients, whereas cribs served a broader clientele under more cramped and unsanitary conditions.
Step-by-step explanation:
For Chinese prostitutes, work in parlor houses differed from that in cribs in several ways. Parlor houses often provided a higher class experience and were usually cleaner, with better working conditions compared to the cribs, which were more cramped and unsanitary. In particular, these parlor houses catered to wealthier clients, offering a more luxurious setting and potentially higher earnings for the women working there. Cribs, meanwhile, were more accessible to a wider range of customers, often providing quicker, less expensive services under poorer conditions. Therefore, the correct answer is C) Parlor houses catered to wealthier clients, while cribs served a wider range of customers.
