### HideShow timer Statistics

A survey of a group of people between the ages of 75 and 80 found that those who regularly played the card game bridge tended to have better short-term memory than those who did not play bridge. It was originally concluded from this that playing bridge can help older people to retain and develop their memory. However, it may well be that bridge is simply a more enjoyable game for people who already have good short-term memory and who are thus more inclined to play.
In countering the original conclusion the reasoning above uses which one of the following techniques?
(A) challenging the representativeness of the sample surveyed
(B) conceding the suggested relationship between playing bridge and short-term memory, but questioning whether any conclusion about appropriate therapy can be drawn
(C) arguing that the original conclusion relied on an inaccurate understanding of the motives that the people surveyed have for playing bridge
(D) providing an alternative hypothesis to explain the data on which the original conclusion was based
(E) describing a flaw in the reasoning on which the original conclusion was based

The writer has given data and a conclusion...he then proposes a new hypothesis.

Conclusion. Bridge players have greater short term memory, therefore bridge helps short term memory.

he/she then proposes a different hypothesis explaining the same data.

Bridge players have greater short term memory, PERHAPS short term memory is a requirement to enjoy the game bridge.

B...

The issue here is about how bridge can improve a person's short term memory.

The passage's conclusion doesn't relate to the issue. Whether people with good short term memory has more interest in bridge has nothing to do with the issue.

Both B and D seem OK. But i would go with B because it accurately sums up the reasoning employed - the reasoning concedes there's a relationship between short term memory and bridge but disputes its threapeutic value as was originally concluded by suggesting an alternative - that bridge was a game enjoyed by people who already had good short term memory - not the other way around that the game itself promoted good short term memory.

B it is.

Vote A. The bad short-term memory people, who always lose, hence do not play card game bridge as often as do good people.

The answer is D. It is giving an alternative explanation to the shortmemorry and bridge game explanation.
