Hi @meisen, thanks for your post.

There is a great deal of textual support in the passage for answer choice (D) - that the Ultimatum Game is implied to be "a type of one-shot, anonymous interaction." See lines 51-57.

Answer choice (E) is wrong because the Ultimatum Game is not, itself, "proof that our emotional apparatus has been shaped by millions of years of living in small groups." It is possible that people's *responses* to this game reflect an emotional evolution, but not the game itself.

Hope this helps. Please let us know if you have any additional questions.

I thought it couldn't be implied since it directly stated it was a one-shot.

Hi @alva,

The passage does not directly state that the Ultimatum Game itself is a "one-shot interaction."

The final paragraph of the passage discusses a "more compelling explanation" for why responders reject low offers in the Ultimatum Game. This has to do with the evolution of our "emotional apparatus." Lines 51 to 54 tell us: "because one-shot interactions were rare during human evolution, our emotions do not discriminate between one-shot and repeated interactions."

As the passage is outlining possible explanations for why responders reject low offers in the Ultimatum Game, we can infer that the Ultimatum Game is an example of these "one-shot interactions" and, therefore, our emotions do not discriminate between it and repeated interactions.

Hope this helps! Please let us know if you have any further questions.
