In order to reduce the number of customer complaints, restaurant-industry consultants recommended that the ChowDown restaurant chain serve more of its dishes at a higher temperature. Accordingly, to guard against diners' receiving plates of cold food, ChowDown managers instructed their cooks to raise the temperature at which meals were served. The cooks followed these instructions conscientiously and began to prepare food using higher heat and use more intense heat lamps to preserve the food's temperature after it finished cooking. Nevertheless, the number of customer complaints rose somewhat.
Which of the following, if true, most helps to explain why acting on the consultants' recommendation failed to achieve its goal?
A. The change in food preparation policy led to an increase in energy bills because ChowDown's kitchens were using more heat.
B. When prepared and served at high temperatures, food can burn customers' mouths and tongues.
C. The amount of heat used to cook a meal does not significantly influence the attractiveness of the meal as it appears on a plate.
D. Most of the food on ChowDown's menus contains meat that must be cooked to a proper minimum temperature in order to kill pathogens.
E. ChowDown has lost some of its regular customers as a result of the high number of unsatisfactory meals that have been served.
