If that insect is a bee, it can only sting once. It only did sting onc

If that insect is a bee, it can only sting once. It only did sting once. So it is a bee.

Structure: Bee --> Sting once
Sting once
----------------------------------------
Bee

Which one of the following exhibits a pattern of reasoning most similar to that in the argument above?


(A) Spring is here. It has to be, because when it is spring, I cannot stop sneezing; and I just sneezed

Structure: Spring --> Cannot stop sneezing
Cannot stop sneezing
-----------------------------------------------------
Spring

Matches perfectly. The order of the sentences doesn't matter, so long as the premises and conclusions match.

If that insect is a bee, it can only sting once. It only did sting once. So it is a bee.

Which one of the following exhibits a pattern of reasoning most similar to that in the argument above?


(A) Spring is here. It has to be, because when it is spring, I cannot stop sneezing; and I just sneezed

(B) When the sky is clear, the atmospheric pressure is high. At the moment, it is clearing up, so the atmospheric pressure is bound to be high soon

(C) Old and brittle paintings are always moved with extreme care. That particular painting is never moved with extreme care. So it must not be old and brittle

(D) Only one more thunderstorm was needed to ruin that roof. But the roof was still fine a month later. There must not have been any thunderstorm over that month

(E) To survive in the wild requires physical stamina like Mark’s. All the same, Mark’s fear of spiders would prevent his survival


Can anyone please explain why "c" is wrong.

old and brittle--- moved with extreme care

not moved with extreme care---> not old an brittle

If that insect is a bee, it can only sting once. It only did sting once. So it is a bee.

Type- similar reasoning
The argument is flawed. Just because the bee did sting only once doesn't prove that it can only sting once. Maybe it could sting again and just hasn't gotten around to it yet?
Also, the author concluded that the sufficient condition (it's a bee) must have occurred on the grounds that the necessary condition appears to have occurred.


(A) Spring is here. It has to be, because when it is spring, I cannot stop sneezing; and I just sneezed- Correct, the necessary condition (can't stop sneezing) might be happening (we can't be sure - we only know that he sneezed, not that he can't stop), and he concludes that the sufficient condition (spring) must also have occurred.

(B) When the sky is clear, the atmospheric pressure is high. At the moment, it is clearing up, so the atmospheric pressure is bound to be high soon- incorrect, no such flaw here

(C) Old and brittle paintings are always moved with extreme care. That particular painting is never moved with extreme care. So it must not be old and brittle- incorrect
'moved with extreme care' is a necessary condition for Old and brittle paintings. Since the necessary condition is absent, so the painting must not be old and brittle.

(D) Only one more thunderstorm was needed to ruin that roof. But the roof was still fine a month later. There must not have been any thunderstorm over that month- incorrect

(E) To survive in the wild requires physical stamina like Mark’s. All the same, Mark’s fear of spiders would prevent his survival- incorrect
