This question asks you to identify hidden assumptions embedded in the speaker’s argument. Examine each statement.

(A) is an assumption of the argument. Barbara told the speaker about two bets, and the speaker assumes those were the only two she made. (She could have made additional wagers.)

(B) is also an assumption of the argument. The speaker concludes that one or the other horse must have won, but that conclusion depends on the assumption that they did not both win.

(C) is also an assumption of the argument. The speaker implicitly assumes that the only reason Barbara would return to the parimutuel window is to cash a winning ticket, as opposed to placing another bet.

(D) is also a hidden assumption, similar to (A).
