Explanation
This question requires us to identify the point of disagreement between Anderson and Lipton. Anderson suggests that worrying about grammar violations is unnecessary due to the natural evolution of language, whereas Lipton asserts the importance of enforcing rules, akin to laws, regardless of changes.
A. (Correct Response) Anderson and Lipton disagree over whether grammar violations should be resisted. Anderson implies that because language changes, such resistance is futile, while Lipton suggests that rules should be enforced regardless of change.
B. Both speakers might agree that a language can evolve into an entirely new language, as Anderson directly mentions evolution and Lipton does not contradict this point.
C. There is no explicit mention of how easily users can adapt to language changes in either statement, so it cannot be the point of disagreement.
D. There is no discussion about the frequency of grammar violations, so it cannot be identified as a point of disagreement between Anderson and Lipton.
E. Both might agree that languages evolve through changes in usage and rules since Anderson explicitly states this and Lipton does not argue against the fact of language evolution itself.
The central disagreement hinges on whether grammar rules should be actively upheld or not, with Anderson taking a more laissez-faire attitude due to the inevitability of change, and Lipton advocating for the enforcement of rules as a principle.
