One reason swimming immediately after eating is thought to be dangerous is that it could cause muscle cramps. But there is no reason to believe this. Muscle cramps are usually caused by muscle fatigue and dehydration, which are unrelated to eating. Reduced blood flow to muscles during digestion might also be a cause, though this is disputed. In any case, not enough blood goes to the stomach to aid in digestion after a meal to reduce blood flow to muscles.

Summarize Argument: Counter-Position
The author concludes that there’s no reason to believe that swimming immediately after eating causes muscle cramps. This is because muscle cramps are caused by either muscle fatigue and dehydration or by reduced blood flow to the muscles. Muscle fatigue and dehydration aren’t related to eating, and eating doesn’t cause enough reduced blood flow to the muscles to cause cramps.

Identify Conclusion
The conclusion is the author’s counter to the belief that swimming immediately after eating causes muscle cramps: “[T]here is no reason to believe this.”

A
Swimming immediately after eating is not dangerous.
This twists the author’s conclusion, which is only that swimming after eating doesn’t cause muscle cramps. The author never suggests swimming after eating is not dangerous for some other reason besides muscle cramps.
B
Reduced blood flow to muscles is not a cause of muscle cramps.
The author acknowledges that reduced blood flow might not be a cause of muscle cramps, but never states that it is definitely not a cause.
C
There is no reason to believe that swimming immediately after eating causes muscle cramps.
This is a paraphrase of the conclusion.
D
Blood going to the stomach to aid in digestion after a meal is not a cause of muscle cramps.
This is a premise.
E
Blood going to the stomach to aid in digestion after a meal would not reduce blood flow to the muscles.
This relates only to a premise. And, it twists what that premise actually says. The author states that there’s not enough blood that goes to the stomach during digestion to reduce blood flow to muscles. This doesn’t mean that there’s no reduced blood flow to muscles at all.
