Bio-chemists at Perck Pharma Corporation have discovered a new type of allergy.  Their research confirms that not only is it caused by pollen of a certain flower, as it was thought, but also the flower has to be pollinated by a certain kind of bee to cause the allergy.

Which of the following would most likely support the data’s implication?

(A) In the absence of the bee, the pollen does not cause allergic reactions
(B) The bee has been shown to be a critical element in the reproduction of the particular flower.
(C) Many cases of the allergy have been observed only in the presence of the bee
(D) In cases in which the allergy does not develop, the flower will grow without the presence of the bee
(E) The onset of the allergy is usually caused by the flower even if the pollen is not present.

A
Both bee and pollen of the flower are required for allergy as per premise. So if bee is not present the allergy reaction is not caused

This is an inference question.

We know that "research confirms that not only is it caused by pollen of a certain flower, as it was thought, but also the flower has to be pollinated by a certain kind of bee to cause the allergy". Therefore, the answer is A since the premise states that the flower must be pollinated by a certain kind of bee

As for C, the passage does not state whether many cases have been observed only in the presence of a bee. Perck Pharma Corporation may have conducted studies with or without the presence of bees and still came to the conclusion that the bee must pollinate the flower for allergy to occur (for example, they could have found traces of the bee in the flowers). In inference question, we have to know something for a fact and C is an assumption. therefore, C is incorrect

To eliminate C

The key word here is Many cases. Many does not mean all.
The conclusion says - in all cases the bee is required to pollinate the flower for the allergy

Such questions are best explained by discussing the conditional statements framework:
https://www.gmatclub.com/forum/veritas-prep-resource-links-no-longer-available-399979.html#/2012/1 ... tatements/

The argument tells us that as per the new research, the allergy happens ONLY IF a particular bee pollinates the flower.

Note how do we establish the ONLY IF relation:
Only if A, then B (Only if "that specific bee", then "allergy")
- B implies A (allergy implies that specific bee)
- Not A implies not B (No bee means no allergy)
If both the above points are established, then we can establish the "only if" relation. (Or if the only if relation is established, then the above two points are its implications)

Option (A) gives you "no bee means no allergy". This helps in establishing the only if relation.

(D) In cases in which the allergy does not develop, the flower will grow without the presence of the bee.
Option (D) gives you "not B implies not A". This does not help us in establishing the only if relation.

Let's look at other options too:
(B) The bee has been shown to be a critical element in the reproduction of the particular flower.
Doesn't help. We want to establish that when the bee pollinates, only then the allergy happens.

(C) Many cases of the allergy have been observed only in the presence of the bee
"Many" is not good enough to establish the "only if bee, then allergy" case.

(E) The onset of the allergy is usually caused by the flower even if the pollen is not present.
This questions the already established fact - this allergy is caused by the pollen of a particular flower.

Is there difference between "only if" and "if" statements?

Previously I understood as below.
If A then B
means
Not B, not A.

Similar concept we use in "x led y".
No Y, no x.

But in case of only if A then B.
If not A, not B.


Please explain. I want to correct myself if I am wrong.

Hi MartyMurray

To eliminate (C), can we say that those cases of allergy might have happened due to other factors caused by presence of the bee, not specifically pollination caused by the bee. Is my reasoning correct?

Bio-chemists at Perck Pharma Corporation have discovered a new type of allergy. Their research confirms that not only is it caused by pollen of a certain flower, as it was thought, but also the flower has to be pollinated by a certain kind of bee to cause the allergy.
Which of the following would most likely support the data’s implication?

The new finding is that the pollen alone is not enough. The allergy occurs only if the flower has been pollinated by a certain bee. So the key implication is that the bee’s involvement is necessary for this allergy to occur.

(A) In the absence of the bee, the pollen does not cause allergic reactions

This is the best answer. It directly supports the idea that without that bee, the pollen will not trigger the allergy.

(B) The bee has been shown to be a critical element in the reproduction of the particular flower.

This is irrelevant. The issue is not whether the bee helps the flower reproduce, but whether the bee’s pollination is necessary for the allergy.

(C) Many cases of the allergy have been observed only in the presence of the bee

This is weaker than A. “Many cases” does not show that the bee is required in all such cases.

(D) In cases in which the allergy does not develop, the flower will grow without the presence of the bee

This does not address the causal claim about the allergy.

(E) The onset of the allergy is usually caused by the flower even if the pollen is not present.

This goes against the passage, which says the allergy is caused by the pollen.

Answer: (A)

Show more
Yes, I think, that reasoning is correct.

Choice C says only that many allergy cases were observed in the presence of the bee. But presence of the bee is not the same as pollination by the bee. So C is too weak because it does not isolate the specific condition the conclusion requires. Even if those allergy cases happened when the bee was around, that alone does not show the allergy depended on the bee’s pollinating the flower.
