Here's another CR question from e-GMAT in this week. Hope you enjoy and learn from it
Chinese restaurants that offer free jasmine tea with meals do better business than similar Chinese restaurants that do not offer it for free. But since restaurants offering this free-tea are more likely to offer food that doesn't contain MSG, a substance that is blamed for causing severe headaches in some people after consuming Chinese food, it is the repeat business of MSG allergic patrons that is responsible for higher business and not the attraction of free-tea.
Which of the following, if true, most strengthens the argument above?
A. Although MSG is a taste enhancer, some people cannot make out the difference between the food prepared with and without it.
B. No study has been able to prove a conclusive relation between MSG and the associated headaches with consuming Chinese food.
C. A large majority of the customers of the Chinese restaurants offering free jasmine tea don't end up requesting jasmine tea.
D. Most restaurants that do not offer free jasmine tea end up not charging less than the usual price for the same when ordered by patrons.
E. Some customers at Chinese restaurants which do not offer free jasmine tea complain of severe headaches right after having a meal at those restaurants
