A.I. Explanation:

Option 1: "In modern society, we must take more time for our neighbors."

Explanation: This option suggests a need for increased interpersonal time, which is not the focus of the text. The author discusses the importance of a standardized measure of time for societal function, not the need for personal time with neighbors.

Option 2: "An accepted way of measuring time is essential for the smooth functioning of society."

Explanation: This option accurately reflects the author's main idea that a common understanding of time is crucial for societal order. The text emphasizes that without a single yardstick of time, social life would be chaotic, supporting this summary.

Option 3: "The traditions of society are timeless."

Explanation: While the text mentions traditions related to timekeeping, it does not argue that these traditions are timeless. Instead, it highlights the necessity of a standardized time for modern society's functioning.

Option 4: "Society judges people by the times at which they conduct certain activities."

Explanation: This option implies a judgmental aspect of timekeeping that is not present in the text. The author focuses on the necessity of a common time measure for societal order rather than societal judgment based on timing.
