Food service operators are seeing one of the most important and growing trends in the past decade – the “gourmetisation” of fast food into a new category of food service called fast casual. One of the strongest restaurant concepts fast casual restaurants do not offer a full table service; however, they do advertise higher quality food in comparison to fast food restaurants. As a result, fast casual restaurants are perceived as an intermediate option between fast food and casual dining, and usually priced accordingly. Fast casual is now the fastest growing category in the food service industry.
The industry relies heavily on human capital for food preparation and customer services. These jobs are usually low paid and require long hours. A large percentage of food preparation and customer services jobs are filled by immigrants and young adults, respectively.
Below is information from two German companies in the fast casual restaurant sub- sector, which may or may not be material.
What conclusions might be made with regards to Company A’s working conditions in comparison to Company B’s?
选项：
A.Company A has more employees and thus its risk associated with working conditions is higher. B.Company A has better working conditions as it conducts more supply chain audits per year. C.Company B probably has better working conditions based on its lower employee turnover and injury rate. D.Company A and B have comparable working conditions as a similar percentage of their employees are exposed to food preparation hazards.解释：
两家公司所在的休闲快餐行业严重依赖人力资本。B公司的员工离职率和受伤率均远低于A公司，说明B公司可以为员工提供更好的工作条件。请问B答案的supply chain audit具体是用来干嘛的
