Why is (E) the right answer choice here, as opposed to (B)?
Stabilizers: Cheap, preserve consistency, but bad for flavor
Low temperatures: Expensive, preserve consistency, better for flavor
(B) suggests: To save money, we should omit the very low temperatures; just use stabilizers to preserve consistency and don't worry about the flavor
Is the idea that the stimulus just remains neutral on flavor, contrary to what (B) suggests?
The stimulus certainly seems to entail the suggestion that cost considerations would encourage ice cream producers to accept higher temperatures, but the stimulus does not also seem to entail an unequivocal recommendation concerning stabilizer use: Contrary to what (B) suggests, ice cream producers might not use very low temperatures (thus reducing costs) AND also not use stabilizers, thus sacrificing consistency for the sake of flavor.
I assume this must be it: The cost considerations mentioned in the stimulus certainly incentivize higher temperatures, but the stimulus does not also entail an unequivocal recommendation concerning stabilizer use. (B) thus does not follow, unlike (E).
