Critical Reasoning: Conclusion Strengthening Questions
A recent survey shows that 86% of the passengers on international flights would not be satisfied with being served cold meals alone on flights lasting for more than 6 hours. Nutritionists agree that because the food in the warm meals served by airlines is cooked, cooled, brought back to room temperature, cooled while in storage, and then reheated again before being served, such food has either no influence, or in serious cases, a negative effect on the health levels of passengers. Based on this information, airlines would be well-advised to implement the serving of cold meals only during flights.
Which of the following, if true, most strongly supports the above conclusion?
Incorrect.
[[snippet]]This answer choice supports serving warm meals by stating that they take less time to prepare, even if this time is only slightly lower than that needed to make a cold meal. This weakens the argument's conclusion.
