The week before the bill to repeal Obamacare came up for consideration in the Senate, one polling agency increased the size of the random sample of U.S. adults they surveyed on this issue from 500 to 1500.

(A) A reduction in the variability of the estimate (B) An increase in the variability of the estimate (C) A reduction in the bias of the estimate (D) An increase in the bias of the estimate (E) A reduction in both the variability and the bias of the estimate
