In a certain game, a large container is filled with red, yellow, green, and blue beads worth, respectively, 7, 5, 3, and 2 points each. A number of beads are then removed from the container. If the product of the point values of the removed beads is 147,000, how many red beads were removed? (A) 5 (B) 4 (C) 3 (D) 2 (E) 0 意思是不是在一个容器里有红黄绿蓝四色珠子，代表值分别为7,5,3,2。现把它们移出容器，如果它们的代表值的乘积为147000，那么要移出多少红色珠子呢？
