Final answer:
The surveyors will check if residents can manage on their own without needing to call 'a. Management' for help, indicating independence and self-sufficiency.
Step-by-step explanation:
The surveyors in the given question are likely to observe whether residents are independent and self-sufficient, or if they frequently need to seek outside assistance. From the options provided, the most appropriate answer would be 'a. Management'. This is because management often deals with the day-to-day operations of resident services, and receiving fewer calls for assistance could indicate that the residents are able to manage on their own without needing to contact them for help.
