Question Stats:

63% (15:22) correct 36% (01:39) wrong based on 30 sessions
In the 1950's sixty percent of treated cancer patients lived at least five years after detection of the disease. Now, sixty percent live at least seven years after detection. This fact demonstrates that, because of improved methods of treatment, cancer patients now live longer after they contract the disease than. cancer patients did in the 1950's.

The conclusion of the argument above depends on which of the following assumptions?

(A) In the 1950's only sixty percent of cancer patients received treatment, whereas now a substantially higher percentage does.
(B) Free medical treatment is more likely to be available now to people who have no health insurance than it was in the 1950's.
(C) Detection of cancer does not now take place, on average, significantly earlier in the progression of the disease than it did in the 1950's.
(D) Physicians now usually predict a longer life for cancer patients after detection of the disease than did physicians in the 1950's.
(E) The number of cancer patients now is approximately the same as it was in the 1950's

1950s
People lived for 5 years after cancer detection

Now
People live for 7 years after cancer detection

This could be for two reasons:
1. The improved medicines help live longer
2. Cancer can be detected earlier

If the author is taking the first reason to be correct, he must be assuming that it still takes as long to detect cancer as it did in 1950s.
