新GRE小短文阅读练习题五十八
Ounce for ounce, blends of different artificial sweeteners match any individualartificial sweetener in sweetening power.When used to sweeten food, blends
greatly decrease the likelihood that consumers will exceed acceptable daily
intakes for individual sweeteners.Blends should therefore be used, rather than
single sweeteners alone, since blends are clearly more healthful, yet equally
effective.
The argument depends on which of the following assumptions?
AWhen ingested together, different artificial sweeteners in the blends do not
interact in a way that makes them harmful to human health.
B Different artificial sweeteners, when used together in food, do not contribute
a more desirable flavor to the food than would any one of them by itself.
C The acceptable daily intake for any given artificial sweetener is a conser-
vative figure that could probably be greatly exceeded at little or no risk.
DConsumers who substitute artificial sweeteners for sugar in their diets
generally keep track of their daily intake of different sweeteners.
E The ill effects on health produced by the intake of excessive quantities of
any single artificial sweetener cannot be reversed by reducing intake later.
