Prospective law students, take a moment to engage in logical reasoning while waiting in line for a delicious burrito.
You read the sign above at a local restaurant. Based solely on the assertions in these statements, which of the following statements is true?
A. Ingredients without GMOs are better than ingredients with GMOs.
B. Chipotle's ingredients are better now than they were in the last 21 years.
C. Chipotle's ingredients are worse now than they were in the last 21 years.
D. It is unknown whether ingredients without GMOs are better than ingredients with GMOs.
Answer: The correct answer is D. All that is known about ingredients with GMOs is that they are "n[o]t . . . better" than ingredients without GMOs. That may also mean that the ingredients are of the same quality. A, B, and C are all based on a value judgment whether ingredients without GMOs are better. Granted, the sign is designed to offer the impression that that ingredients without GMOs are "better," given the assertion that Chipotle "ha[s] been striving to make our ingredient better," and here is a step regarding its ingredients. But the first sentence cannot cure the lack of information in the second sentence.
