Barrys Barbecue is a restaurant chain that advertises itself as

only? where they mentioned?
Plus one more reason i feel B is not working here is, "At Barry’s, whenever a diner books a reservation and mentions a food allergy, the kitchen staff is prohibited from preparing multiple dishes on the same grill." means if we think here in relation of cause and effect, both, reservation and food allergy are important to lead effect of prohibition. And B is only talking about reservation. Thats why i eliminated B.

I am confused between A and D.

"A. The kitchen staff at Barry’s sometimes prepares multiple dishes on the same grill." - I kept it in hand as an alternative in case there was no better option. The only problem is the word "sometimes" which doesn't seem to resemble the phrase in the last sentence -"would be the case under normal circumstances." "Under normal circumstances" sounds more like 'all the time' than 'sometimes'. However, it is indeed an alternative to the correct answer.

"D. Limiting cross-contamination from multiple dishes on the same grill is the most effective way to avoid issues for diners with food allergies." I hoped to lean more toward this, as Barry's method ensures that there's 'NO' cross-contamination. Which seems to me that it has been the best option for them to limit cross-contamination. But there's no proof of success mentioned for this method to be the most effective one either. So, 'The most effective' part as an absolute indication is what bugs me a little.

I guess not choosing the absolute might be a wise choice here. That being said option A might be the answer.

A. The kitchen staff at Barry’s sometimes prepares multiple dishes on the same grill.
The argument states that whenever a person with food allergy makes a reservation at Barry's, the kitchen staff will be prohibited from cooking on the same grill different dishes. This means that when nobody makes such a reservation, kitchen staff is not prohibited from cooking different kinds of dishes one the same grill, and given that it takes less time, the staff probably prepares multiple dishes on the same grill in this case

B. Barry’s will not make special kitchen accommodations for diners who do not make a reservation.
Making kitchen accomodations for diners is not conditioned by making a reservation. Only thing here is that when a person makes a reservation in advance he or she is sure of the accomodations.

C. Not all restaurants follow food allergy precautions to avoid cross-contamination between multiple dishes.
Out of scope

D. Limiting cross-contamination from multiple dishes on the same grill is the most effective way to avoid issues for diners with food allergies.
"Most-effective way" is too strong. Nothing in the argument indicates this is true.


E. Diners with food allergies are generally willing to be patient with longer wait times in order to avoid cross-contamination between dishes.
Same as D, nothing in the argument indicates that customers with food-allergies are willing to wait longer times. Maybe if these customers were the majority of the patrons of Barry's ?

This ensures that there is no cross-contamination between dishes, but also can result in longer wait times as fewer meals can be prepared than would be the case under normal circumstances.
