Critical Reasoning

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

Which of the following is an assumption on which the argument depends?

(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.

(B) Not all forms of glucose are equally likely to result in this discomfort.

(C) Ice cream is not the only food to which glucose is commonly added.

(D) Apart from glucose, there are no substances commonly present in ice cream that would cause discomfort to diabetics.

(E) Glucose is not naturally present in the ice cream produced by these ice cream companies in amounts large enough to cause discomfort to diabetics who eat this ice cream.

IMO: A
