Premature hair loss can often be traced back to skin irritation caused by any number of environmental factors. However, removing the factors that led to skin irritation from the environments of the afflicted frequently does not stop the balding. Obviously, some other cause for premature balding besides skin irritation caused by environmental factors must exist.
Which of the following, if true, would most weaken the conclusion above?
A. Very few people suffering from premature hair loss caused by skin irritation regain their lost hair after eliminating the environmental factors that led to skin irritation.
B. Some individuals never experience premature balding despite exposure to environmental factors that irritate their skin.
C. Many people report that the environmental factors that irritate their skin are the ones that are most difficult to avoid.
D. Many common environmental factors generally begin to irritate the skin a few hours after actually coming into contact with them, making it difficult to observe links between specific environmental factors and the balding.
E. Very rarely does skin irritation caused by environmental factors cause a condition more severe than premature balding.

We have to find an answer choice that will make us believe that the environmental factor is the cause.
A. Very few people suffering from premature hair loss caused by skin irritation regain their lost hair after eliminating the environmental factors that led to skin irritation.
>Talks about regrowth of lost hair, not whether the balding process stops.
B. Some individuals never experience premature balding despite exposure to environmental factors that irritate their skin.
>This shows that skin irritation doesn't always cause balding. But we have to find something that will make us believe that the environmental factor is the cause.
C. Many people report that the environmental factors that irritate their skin are the ones that are most difficult to avoid.
>Difficulty avoiding irritants is irrelevant because the argument already discusses cases where factors were removed.
D. Many common environmental factors generally begin to irritate the skin a few hours after actually coming into contact with them, making it difficult to observe links between specific environmental factors and the balding.
>Correct. If there is a delay, it is very difficult for a person to correctly identify which environmental factor is actually causing the problem. Therefore, when people think they are removing the factors, they are likely removing the wrong things while the actual irritant remains in their environment.
E. Very rarely does skin irritation caused by environmental factors cause a condition more severe than premature balding.
>The severity of other conditions has nothing to do with whether persistent balding must have another cause.

Hi MartyMurray KarishmaB
I had eliminated (D) with the reasoning that we are given in the argument "removing the factors that led to skin irritation..", and (D) tries to challenge this fact given in the argument by giving us information "making it difficult to observe links between specific environmental factors and the balding".
Could you please help me understand what is wrong with my reasoning?

There's nothing wrong with your reasoning. The passage states as fact that balding continues after the factors are removed. So, (D) doesn't work as a weakener because of exactly the issue you've brought up. It tries to challenge the fact presented rather than weakens the case for the conclusion by indicating that, even though the presented facts are true, there's reason to believe that the conclusion is not.
