Reading the passage
B's racetrack comparison makes its account concrete: the apparent condition of a horse changes expectations and therefore the odds. We need something B uses that A does not. An item mentioned in A fails that requirement even if B also mentions it.
Working the answers
- A
Neither account discusses market crashes. A criticism of a prediction is not a description of a crash.
- BCorrect
B explicitly asks us to “Think of markets as racetracks” and follows the horse's apparent condition through changes in the odds. A's examples are election contracts and a fictional-stock experiment; it doesn't use racetracks.
- C
A discusses the two traders given “inside knowledge” and says everyone soon behaved like insiders. That alone rules it out for a B-but-not-A question.
- D
A compares the Iowa market with election polls, and B also compares markets to polls. This is shared material.
- E
A explains how participants buy and sell contracts paying a dollar if a candidate wins. Contracts therefore cannot be the reference unique to B.
