Which of the following is an assumption on which the argument depends?
(A) The workers who uncovered the coins did not take for themselves a significant number of coins before reporting their find.
(B) The hoard of coins would not bring in more if broken down into small parcels to be sold individually than if sold as a single quantity.
(C) The appearance on the market of thousands of additional coins of this type will not significantly affect the status of these coins as rarities.
(D) It is not possible to determine whether the hoard of coins was buried by people who were then its legal owners.
(E) Whoever might sell the coins would be sufficiently knowledgeable about such sales to secure the highest possible price for the coins.
答案是c，为什么d不可以呢，取非以后“(D) It is possible to determine whether the hoard of coins was buried by people who were then its legal owners.”
既然是别人的东西不就不能在市场上转手吗
