Look at A.

It says something "theoretically" => Safely =>Makes sense, Could be wrong, but who cares to validate.

Hence A

Though it has 'theoretically', it is actually LOGIC based and perfect math. Check out the following link for a great explanation:

+1 A

We can identify the smallest egg identifying in which egg the wasp laid the smallest number of eggs.

All options except option A introduces new information into the context.

Additionally, by knowing the egg laying pattern of the wasp, the smallest host egg can be identified.

Parasitic wasps lay their eggs directly into the eggs of various host insects in exactly the right numbers for any suitable size of host egg. If they laid too many eggs in a host egg, the developing wasp larvae would compete with each other to the death for nutrients and space. If too few eggs were laid, portions of the host egg would decay, killing the wasp larvae.

Which of the following conclusions can properly be drawn from the information above?

A) The size of the smallest host egg that a wasp could theoretically parasitize can be determined from the wasp's egg-laying behavior.
B) Host insects lack any effective defenses against the form of predation practiced by parasitic wasps.
C) Parasitic wasps learn from experience how many eggs to lay into the eggs of different host species.
D) Failure to lay enough eggs would lead to the death of the developing wasp larvae more quickly than would laying too many eggs.
E) Parasitic wasps use visual clues to calculate the size of a host egg.

E) Parasitic wasps use visual clues to calculate the size of a host egg.

With a kind of inference question, the most appropriate way is to find the SCOPE of the argument.

For example, with this argument, the below words will be the scope: Number of eggs, size of host eggs, the reasons of decaying eggs or death of insects, behavior in laying eggs of insects.

A, In scope. This is the correct answer.
B, Defenses against predators is out of scope.
C, Exp laying in different host species is out of scope
D, The speed of dying between two reasons mentions in the argument. Not mentioned
E, How the parasitic wasp can realize the size of host egg is not mentioned in the paragraph.

That's right.

(A) is making a claim that there is a connection between size of host egg to be parasitized and wasp's egg laying behavior. And we have information to support that in the passage.

Laying a lot of eggs means the size of parasitized host egg must be large. Laying few eggs means size of parasitized host egg must be small.

We basically were able to find a conclusion that could be drawn from the passage - this is the same as an inference question, just rephrased in a different way. With inference questions, we have to find an answer choice that is the "argument/conclusion" and then find information in the passage that would support and make that "argument/conclusion" valid.

A is right here.

I used process of elimination.

(B) Host insects lack any effective defenses against the form of predation practiced by parasitic wasps. >> Noting about host insects defensive ability is mentioned in the passage. Out of scope.
(C) Parasitic wasps learn from experience how many eggs to lay into the eggs of different host species. >> Might be true, but no evidence of experimenting given in passage.
(D) Failure to lay enough eggs would lead to the death of the developing wasp larvae more quickly than would laying too many eggs. >> Out of scope.
(E) Parasitic wasps use visual clues to calculate the size of a host egg. >> We don’t know this from the passage.

What we learn about the parasitic wasp is that it knows exactly how many eggs to lay depending on the size of the host egg. Therefore, if the wasp lays x number of eggs we know that it will correspond to a certain size of host egg. From this information, we can figure out the largest sized host egg a wasp could parasitize and the smallest host egg it could parasitize. In the case of smallest egg, it would lay only a limited number of eggs. Regardless of that number, it's egg laying behavior, i.e., how many eggs it lays, will give indicate the size of the host egg.

Interesting question. I see why A is the correct answer, but I picked C since the question stimulus says explicitly that parasitic wasps lay the right number of eggs given the size of the host egg. I thus concluded that these wasps know the proper number of eggs to lay because they have done this before.

(B) Host insects lack any effective defenses against the form of predation practiced by parasitic wasps.

(D) Failure to lay enough eggs would lead to the death of the developing wasp larvae more quickly than would laying too many eggs.

(E) Parasitic wasps use visual clues to calculate the size of a host egg.

This is my explanation.
I followed an elimination method.
B. is an assumption, but not a conclusion (hence cannot be the answer)
C. The learning behavior of the wasps or previous egg laying events are not mentioned in the stimulus. Therefore, incorrect
D. The stimulus does not mention anything about the success rate of the laying few/more eggs (cannot be the answer)
E. The stimulus does not mention anything about visual clues.

The only option that does not include any outside information and has some relevance to the stimulus is A. Pick A

The stimulus doesn;t mention behavior either ... can you explain the answer

Hi Roobika,

In my opinion the stimulus does mention behavior. In that the way the wasps select the exact number of eggs to place inside a host, that to me is a 'behavior'.

So A is correct because if you watch enough wasps you can see the smallest size they choose to lay their eggs in.

Hope that helps.
