Knewton Challenge, 1/24/11 (Glucose Intolerance)

We need an assumption to create a link between the premises and the conclusion.

Premise 1: Diabetes is a disease in which the body does not produce or properly use insulin, a hormone that is needed to convert glucose into energy needed for daily life.

Premise 2: Because ice cream commonly contains glucose in the form of sucrose, diabetics generally experience discomfort after consuming even a small serving of ice cream.

Conclusion: However, since there are several ice cream companies who add sucrose to none of the ice cream they produce, diabetics are able to eat ice cream without experiencing discomfort due to glucose intolerance afterward.

As other friends explained A,B and C are quite out of scope and can be ignored easily. D is out too, because Glucose already mentioned as main factor of this disease.


E is correct assumption. It says that in order to make sure that that ice cream without Sucrose is safe, we need to assume that it does not have glucose, the main enemy of diabetes either.

The original question wrote:(A) These ice cream companies have been able to duplicate the taste of sucrose derived from glucose by means that do not involve adding any potential substances that may be of discomfort to diabetics.
We'd simply add a "not" before the main verb, so that it read:

"These ice cream companies have NOT been able to duplicate the taste of sucrose...."

This statement does not affect the Conclusion since it still refers to taste. I think your question is about whether this is the correct Negation or if we should negate the "do not" part later on: when using the Negation Test, always negate the main verb of the answer choice.
