Answer:
(A) Fails to distinguish between purchasing and consuming.
Step-by-step explanation:
The given argument could be characterized as flawed due to its 'failure to differentiate between purchasing and consuming.' It exemplifies a scope-shift as the claim is accurate but the point of influence shuffles that misleads the reader and makes the argument flawed. It states that aged people buy more ice-cream in comparison to the young ones while the younger ones consume more so there lies a possibility that the elderly owners might have bought for the younger members of their family. Thus, this makes the argument fallacious.
