It has been discovered that a chemical compound present in a liquid sprayed by pinkback ants as a defense mechanism contains antiseptic properties very useful in the treatment of minor flesh wounds. The volume of the chemical stored in a pinkback's glands is so small that it took scientists more than a year to acquire a sufficient amount for research purposes. Clearly, it will be very expensive, if not impossible, to use the chemical in commercial applications since such applications require much greater amounts than those used during research.

The answer to which of the following would be most useful in evaluating the argument?


A What kind of commercial applications could benefit from the presence of such a chemical?

B Does the chemical have properties that would make it useful for the healing of ailments other than flesh wounds?

C When the chemical is drawn from the glands of a pinkback ant, how long does it take for the ant to reproduce the missing amount?

D What alternative sources of other chemicals used for the treatment of minor flesh wounds are there?

E Can the compound be synthetically produced without it losing any of its characteristics?

In conclussion the autor states that : Clearly, it will be very expensive, if not impossible, to use the chemical in commercial applications since such applications require much greater amounts than those used during research.

Now, if pinkback ants are the only source for the chemical and thus difficult to get... then yes... it will be expensive to get the compound in greater amount.but, on the other hand if there are any other ways to get the same chemical then the implications will differ.

Option E : Can the compound be synthetically produced without it losing any of its characteristics? argues in the same line.
Thus ans E

Yes E makes more sense but unable to eliminate C

What if the ant reproduces the missing amount of chemical within 10 mins
So in that case it may not be expensive just time consuming

And even if a synthetic chemical is possible may be the process to create one will be very expensive

I might not be correct,but, somehow the argument states the causal relationship in the following order:
Small amount in ants - > long time to get any considerable amount for research - > thus expensive when required for commercial applications that needed much more
Thus to me , if the only source is ant , the chemical will continue to be expensive.
But if there is an alternative way to get the resource , the cost could be less.

Now, time to reproduce was not mentioned in the argument. But, for sake of argument lets assume 'the ant reproduces the missing amount of chemical within 10 mins' . Then still there will be too many queries : such as , how many ant will be sufficient ( 1, 1000, 1M, 1B) ? What amount is sufficient for the experiment ? What is the cost of getting the amount in this process ?

Although in this line ... one can attack the Ans E as well .. what is the cost of synthetic process ? R& D Cost ? etc etc.

For C to be correct :
What if the ant reproduces the missing amount of chemical within 10 mins
needs to be present in the question para, which is not there.

Hope it helps, if so kudos pls !!

Cheers :)

Conclusion: It will be very expensive, if not impossible, to use the chemical in commercial applications.

Assumption: This argument explicitly assume that the chemical compound cannot be produced by any other source which may be cheaper than producing this chemical from ants.

Paying attention to the conclusion is very important. It talks about the cost factor not the benefit factor. So, A and B can be eliminated.
C is out of scope.
D is incorrect because we are not interested as to how those wounds can be treated.
E is the answer.

Sciences keeps discovering substances that could be useful to man.

If the chemical in pinkback ant were very useful, we would actually produce it.
For example the spider web has been found to be more powerful or stronger than nylon
so there has been ropes made from the spider web but we don't have commercial quantities

Why not B?

The para says it treats minor flesh wound---takes long for ants to replenish and cost of synthesis is high..
Is it really logical to invest so much by knowing that it treats only minor flesh would.
Hence the knowledge that whether it can treat other wounds can't be ignored.

Conclusion ->
It will be very expensive, if not impossible, to use the chemical in commercial applications since such applications require much greater amounts than those used during research.

A What kind of commercial applications could benefit from the presence of such a chemical?
Irrelevant to the scope of the argument.

B Does the chemical have properties that would make it useful for the healing of ailments other than flesh wounds?
Other than flesh wounds,went out of scope

C When the chemical is drawn from the glands of a pinkback ant, how long does it take for the ant to reproduce the missing amount?
They already know it took initially a year for its production, why do we have to question that ??-> Out

D What alternative sources of other chemicals used for the treatment of minor flesh wounds are there?
Alternative sources again, went ahead the scope, if there are already alternate sources present, why are we doing such studies, irrelevant

E Can the compound be synthetically produced without it losing any of its characteristics?
Lets do Yes no test here
Yes the compound can be synthetically produced without it losing any of its characteristics
Weakens the conclusion, that no it wont be expensive

No compound cannot be synthetically produced without it losing any of its characteristics
Strengthens the conclusion, yes it will be expensive

Situation: The conclusion states that it will be very expensive to use the chemical in commercial applications since it's difficult to extract this chemical and the commercial applications require much greater amounts than those used for research.

Assumption: The argument assumes that the chemical compound cannot be produced by any other cheaper way.

Objective: To find an option that evaluates the above scenario.

A What kind of commercial applications could benefit from the presence of such a chemical?-Incorrect. Irrelevant to our discussion.

B Does the chemical have properties that would make it useful for the healing of ailments other than flesh wounds?
-Incorrect. Irrelevant to our discussion.

C When the chemical is drawn from the glands of a pinkback ant, how long does it take for the ant to reproduce the missing amount?-Incorrect. Even if pinkback reproduces the chemical immediately, it will still be hard to extract the chemical quickly and in large quantity.

D What alternative sources of other chemicals used for the treatment of minor flesh wounds are there?-Incorrect. Irrelevant to our discussion.

E Can the compound be synthetically produced without it losing any of its characteristics?- Correct. If the compound can be alternately produced, then the conclusion might not hold. If it's not possible to alternately produce it, the conclusion holds. Therefore, this option is of interest to our discussion.
