Virulent microbes, which are transmitted mainly through drinking water, are the most common cause of waterborne diseases. According to the World Health Organization, such diseases cause almost two million deaths every year, and an estimated 65 percent of these fatalities are caused by microbial organisms. Clearly, this number can be significantly reduced if drinking water is treated with anti-microbial agents before it is supplied to consumers.
Which of the following would it be most useful to establish in order to evaluate the conclusion drawn above?
A. Whether treating drinking water with anti-microbial agents would be more expensive than treating it with conventional water purification processes
B. Whether the fatalities caused by waterborne diseases would be reduced if alternative forms of medical treatment were used
C. Whether the figures reported by the World Health Organization include the number of deaths caused by allergic reactions to medicines prescribed for the treatment of waterborne diseases
D. Whether drinking water is contaminated at water processing plants or while being delivered to consumers
E. Whether drinking water contains any harmful contaminants other than disease-causing microbes
Which of the following would it be most useful to establish in order to evaluate the conclusion drawn above?
A. Whether treating drinking water with anti-microbial agents would be more expensive than treating it with conventional water purification processes
B. Whether the fatalities caused by waterborne diseases would be reduced if alternative forms of medical treatment were used
C. Whether the figures reported by the World Health Organization include the number of deaths caused by allergic reactions to medicines prescribed for the treatment of waterborne diseases
D. Whether drinking water is contaminated at water processing plants or while being delivered to consumers

Clearly, this number can be significantly reduced if drinking water is treated with anti-microbial agents before it is supplied to consumers.
Which of the following would it be most useful to establish in order to evaluate the conclusion drawn above?
CONCL- Clearly, this number can be significantly reduced if drinking water is treated with anti-microbial agents before it is supplied to consumers.
A. Whether treating drinking water with anti-microbial agents would be more expensive than treating it with conventional water purification processes- expense is not the question
B. Whether the fatalities caused by waterborne diseases would be reduced if alternative forms of medical treatment were used- alternative is not the point
C. Whether the figures reported by the World Health Organization include the number of deaths caused by allergic reactions to medicines prescribed for the treatment of waterborne diseases- irrelevant
D. Whether drinking water is contaminated at water processing plants or while being delivered to consumers- CORRECT
hint: if drinking water is treated with anti-microbial agents before it is supplied to consumers.
drinking water is contaminated at water plant- then plan will work, concl is protected.
drinking water is contaminated while delivery- plan will not work, concl is destroyed.
E. Whether drinking water contains any harmful contaminants other than disease-causing microbes- irrelevant
ANS- D

A) This is not relevant to the scope of the question. Both cases could be true, and it would not impact the validity of the argument.
B) This is also not relevant to the scope of the question. Even if alternative forms of treatment could be used, it does not tell us if treating the water itself would be effective or not.
C) This is somewhat tricky, but does not impact the argument. Even if the figures did include the allergic reactions, if the water treatment is effective, then those deaths would also be reduced (If there is no need for treatment, then there would be no allergic reaction to the medication as there is no reason to take it)
D) This is the correct choice. If the water is contaminated at the plant itself, then it is more certain that the plan will work, since the water is treated at the plant, and the contamination will be removed. However, if the contamination occurs during the shipping process to consumers, then the treatment would not be effective at all, because it would be done at a stage in which the water was not contaminated.
E) Much like A and B, E is also not relevant. The treatment of water may still reduce the infections from the contamination discussed in the argument, with or without additional contaminants.
