What humorous anecdote is associated with the Coolidge Effect?

• A. A story about Coolidge visiting a chicken farm to observe a rooster's vigor.
• B. A tale of Coolidge awarding a prize to a rooster.
• C. A joke about Coolidge testing a rooster's stamina in a lab.
• D. A story about President Calvin Coolidge observing a rooster's vigor at a chicken farm.

Answer: (D)

The main idea tested is the origin story behind the Coolidge Effect, the humorous tale used to illustrate how a male’s sexual interest can rebound with new partners after satiation with a single partner. The best choice precisely captures the famous anecdote: President Calvin Coolidge observing a rooster’s vigor at a chicken farm. This framing matches the well-known joke that gave the name to the effect. Other options shift details—such as removing the president, changing the setting, or altering the action—and don’t align with the classic anecdote. So this option best conveys the intended humorous origin of the concept.
