Whorfian tubules have an inside diameter equal to their length, a density half that of water, and a mass that is immeasurably small. A physicist isolated an entity less dense than water, with insufficient mass to measure, and a length exactly equal to the diameter of its inside.


It would be certain that the physicist had isolated a Whorfian tubule if it were concluded by the physicist that

the physicist had been looking specifically for Whorfian tubules
Whorfian tubules are the only entities of immeasurably small mass with an inside diameter equal to their length
the density of what he had isolated was exactly half that of water
Whorfian tubules are only found under the conditions that the physicist had duplicated
Whorfian tubules were the only entities half the density of water with an immeasurably small mass

Chose C....but B is definitely better than C.....

This question made me realize the importance of selecting the best answer rather than than "finding" the answer amongst the choices...

Whorfian tubules have an inside diameter equal to their length, a density half that of water, and a mass that is immeasurably small. A physicist isolated an entity less dense than water, with insufficient mass to measure, and a length exactly equal to the diameter of its inside.

It would be certain that the physicist had isolated a Whorfian tubule if it were concluded by the physicist that

the physicist had been looking specifically for Whorfian tubules - irrelevant
Whorfian tubules are the only entities of immeasurably small mass with an inside diameter equal to their length - the reason for him not to consider the WT.
the density of what he had isolated was exactly half that of water - this is talking about only one component of the WT (B overpowers C)
Whorfian tubules are only found under the conditions that the physicist had duplicated - out of scope
Whorfian tubules were the only entities half the density of water with an immeasurably small mass - This is a lot closer to B for me.

Can anyone explain exactly why "E" is wrong.

I'm confused if question is about finding an assumption or about finding sub-conclusion?

A: Even if he had been looking only for Whorfian tubules he could have found something else with the same properties, hence wrong
B:Correct. If something else had similar properties this would fall apart (try negation test)
C: Exactly half of water - Not necessary for a conclusion
D: Could be true, but there could be other things also under same conditions, hence not a conclusion
E: Omits inside diameter equal to length hence wrong.

Answer B

In choice E, it is mentioned "half the density"

But in question "A physicist isolated an entity less dense than water, with insufficient mass to measure, and a length exactly equal to the diameter of its inside.", this point is not mentioned... thats y choose B over E

Whorfian tubules have an inside diameter equal to their length, a density half that of water, and a mass that is immeasurably small. A physicist isolated an entity less dense than water, with insufficient mass to measure, and a length exactly equal to the diameter of its inside.
WT : D(wt) = 0.5*D(water), L=D, very small length
Physicist found: st that has D(st) < D(water), L=D, very small length



It would be certain that the physicist had isolated a Whorfian tubule if it were concluded by the physicist that

the physicist had been looking specifically for Whorfian tubules Irrelevant
Whorfian tubules are the only entities of immeasurably small mass with an inside diameter equal to their length true
the density of what he had isolated was exactly half that of water We cannot conclude that it is WT
Whorfian tubules are only found under the conditions that the physicist had duplicated Was there any duplication? No
Whorfian tubules were the only entities half the density of water with an immeasurably small mass not true
