I agree it is D and I chose by POE. Only D is somewhat consistent with the passage.

A has no bearing on whether the recommended usage for humans is harmful or not.

B says meets all industry standards for safety = what safety ? production safety or human consumption safety

C Not clear how birth defects could exonerate the product from being labeled one way or the other

E sincerity isnt too big a deal// the insecticide could still be as leathal or benign.

Not having an evidence in last 20 years is not sufficient to prove that there is no harm. May be there was no reserach ever done on this in last 20 years. There could be lots of evidences in next 2 months so A can't be right.

I am just trying to understand option A.

"would almost certainly have been discovered after two decades of use" suggests that there is no need for further research to identify harmful effects. A says that 20 years of usage, is enough to get evidence. That means 20 years is a good enough time to say that "there is no evidence". The argument says that there is no evidence of harmful effects, if the insecticide is used in recommended way. Is n't A strengthening the argument?

If there has been no evidence of harmful effects of this insecticide after two decades, it is unlikely that there could be any harmful effects on humans.

Only A is relevant.

I can see why it could be D, but there is an amount of uncertainty in both the options.
In A, it is "almost certainly", so there is a chance of the claim being proven wrong.

In D, it is "a vast majority", so what if the small percentage of users, who are not federal agencies, are affected by this insecticide?

Hmmm... even as I am type this, I am leaning more towards D.

I would have never selected A - never ! If A is OA, I need a lot of logical explanations !

D says, federal agencies study only "application" and not "effects" and they neither concluded "lack of effects". No?

In that case, can we conclude anything from D?

Yes , we can. The company rep said if chemical is used as recommneded, it will cause no harm and argument says this statement is true.

So, if the application is monitored to assure that chemical is used in accordance with the company's recommendation then only it can be true that it didn't cause any harm to anybody.

There is no harm found reported in 20 years doesn't mean that there was no harm.

It took 15+ years to detect how harmful DDT was.

If A is OA - I didn't get it !

SPOKESPERSON'S CONTENTION - there is NO EVIDENCE of harmful effects when the insecticide is consumed within recommended limits

Stem says ASSUME the above is true -

meaning - it is actually true that there has been no evidence of harmful effects when the insecticide has been used correctly.

What additional information can strengthen the argument - THAT THE INSECTICIDE HAS INDEED BEEN USED CORRECTLY

Choice D provides just such an alternative.

the passage says that there will be no health problems if the insecticides are used in recommended way. D only says that the insecticides are used in recommended ways. So how does D substantiate that there will not be any health problem if the insecticides are used in recommended way.

A for me

I agree D says: the insecticide was used in the recommended way

But we are talking of only "vast majority". What about remaining?Something is true for majority does nt mean that is valid for everybody.
Majority of users might have right equipment that helps them in using insecticide in the recommended way. And the Minority might not have that good equipment and still used insecticide in the recommended way and got into problems.

Also, federal agencies have not published what they found when the insecticides were used in recommened way. We have to assume here that spokesperson of the company knows about the effects of application by federal agencies in the recommended way. We know nothing about problems faced by minority.
