"No data on shelf life in the passage → so shelf life can't be an assumption"
This is backwards.What an ASSUMPTION Actually IsAn assumption is what the argument
takes for granted without stating it.
Think about it: If the passage STATED something, it wouldn't be an assumption—it would be a premise.
Assumptions live in the SILENCE of an argument.Apply This to Your Logic
The vendor's argument:
- "5-for-4 deal worked for marmalade"
- "So I'll use the same deal for radicchio"
What's missing? Any acknowledgment that these products are fundamentally different.
Marmalade = lasts 365 days
Radicchio = lasts 5-10 days
The vendor
never addresses this. She just assumes "what worked for one will work for the other."
By staying silent on this massive difference, she's ASSUMING it doesn't matter.You're right that if something isn't mentioned, we can't add random facts.
But here's the distinction:
Can't assume: "The vendor is left-handed" (irrelevant + not mentioned)
Must be an assumption: When the argument compares two things but ignores a critical difference between them
The vendor is literally saying: "These two products are similar enough for the same strategy"
Without addressing that one spoils 70x faster than the other
That silence = assumption that the difference doesn't matter.
Let's destroy the vendor's plan:
Negate (B): "Consumers who buy bulk marmalade (1-year shelf life) will NOT buy bulk radicchio (5-10 day shelf life)"
What happens? The entire plan falls apart. Nobody buys 5 bunches of something that rots in a week. The 5-for-4 deal fails completely.
This proves (B) is necessary for the plan to work.Nayana24
But there is no data on shelf life period
NO DATA NO ASSUMPTION
So i eliminated option b) and went with a) as it was next closest answer one can chose
