hey @carcass doesn't option A, strengthens the argument. I thought the answer is b. how to tackle weaken type question?

OPTON B doesn't clearly specifies the difference in magnitudes of batteries. For instance, it may be possible that batteries in 1950s were 99.9 percent harmful and batteries in 1980's are 99.8 percent harmful(or visa versa).(So batteries are still harmful so doesn't weakens)

I couldn't decide between A and D. Why is D wrong?

We need an explanation why the argument is weak.

A says that the studies referred to 1950 and basically they are no longer valid or old.

D instead talks about the leakage by the manufacture which is out of scope.

We care of the piles up, the amount in the dump NOT a flaw manufacture process

Isn't the ending argument about the quality of ground water? So shouldn't the likelihood of a battery leak also play a role in this? Suppose there is a huge pile of batteries but they aren't that likely to leak vs. a relatively smaller pile but they are very likely to leak. Chances are, the the former would be better for ground water right?

The problem here is that the study in 1950 DOES NOT reflect the actual conditions

Compared to typical 1980's landfills, typical 1950's landfills contain a negligible number of batteries.

Option C if does something, it strengthens the argument. It shows that toxicity could have been higher in 1950s than 80s, if that were really the case - the argument that since the 1950s landfills were not contaminated, the 80s will also not be is weakened.
