Question
Situation: Fastsnow is planning to market wastewater purification systems that work by spraying a mist that freezes on contact with cold air. The sudden freezing kills bacteria. Because the system works only at cold temperature, municipalities using it will still need to maintain a conventional system
Which of the following, if true, provides the strongest grounds for a prediction that municipalities will buy Fastsnow's purification system despite the need to maintain a conventional purification system as well? Enter the answer in the blank.
A. Bacteria are not the only impurities that must be removed from wastewater.
B. Many municipalities have old wastewater purification systems that need to be replaced.
C. Conventional wastewater purification systems have not been fully successful in killing bacteria at cold temperatures.
D. During times of warm weather, when it is not in use, Fastsnow's purification system requires relatively little maintenance.
E.Places where the winters are cold rarely have a problem of water shortage.
___

Answer:

Reasoning: Which statement provides the strongest grounds for thinking that at least some municipalities will buy the purification system despite the need to maintain a conventional purification system as well? The passage tells us why a municipality using a Fastsnow wastewater purification system would still need a conventional system. But why would a municipality want the Fastsnow system in addition to a conventional system? If conventional systems are not fully effective at cold temperatures, the Fastsnow system would allow municipalities that sometimes experience cold temperatures to purify their wastewater more effectively.
A. There is no basis in the passage for determining whether the Fastsnow system will help remove impurities other than bacteria from wastewater. If it does not, this answer choice implies that the Fastsnow system would not be sufficient for purifying wastewater. This would actually undermine the prediction.
B.The passage states that municipalities using the Fastsnow system would still need a conventional system. Thus, the old conventional wastewater systems would still need to be replaced with new conventional systems. This answer choice provides no reason to think municipalities would buy the Fastsnow system.
C.Correct. This statement, if true, would strengthen the prediction, because it provides a valid reason why the Fastsnow system could be needed alongside conventional ones: it is more effective in cold weather.
D. Although this claim does undercut one reason for thinking municipalities might not be likely to purchase the Fastsnow system, it provides little reason to think that they will purchase such a system. Perhaps in times of cold weather, the Fastsnow system is very expensive to maintain.
E.The issue of whether or not there are water shortages in places where winters are cold is not directly relevant. If conventional wastewater systems are sufficient to purify water in such places, municipalities would not need the Fastsnow system (as they would still need to maintain a conventional purification system).
The correct answer is C.
