Hi there,
I looked at this question, scanned the answer choices, and saw immediately the answer. I later realized there were some other possible answer choices, which I probably should have considered, but looking back, I'd probably be in two minds about whether that answer choice was correct. How'd you go about eliminating the other answer choices?
Thanks again.

Snowmaking machines work by spraying a mist that freezes immediately on contact with cold air. Because the sudden freezing kills bacteria, QuickFreeze is planning to market a wastewater purification system that works on the same principle. The process works only when temperatures are cold, however, so 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 QuickFreeze's purification system despite the need to maintain a conventional purification system as well?

(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, QuickFreeze's purification system requires relatively little maintenance.

(E) Places where the winters are cold rarely have a problem of water shortage

Which of the following, if true, provides the strongest grounds for a prediction that the Purification Municipalities will buy QuickFreeze's system despite the need to maintain a conventional Purification system as well?

(A)Bacteria are not the only impurities that must be removed from wastewater. Out of scope or actually can even be used to weaken the argument. Wrong answer

(B)Many Municipalities have old wastewater Purification Systems that need to be replaced. Out of scope. Has no relevance at all.

(C)Conventional wastewater purification systems have not been fully successful in killing bacteria at cold temperatures. The argument says that these machines can kill bacteria at cold temperatures. If there is not a fully successful purification system to kill bacteria at cold temperatures then it would make sense to buy new technology which we beleive would be successful. Answer

(D)During times of warm weather, when it is not in use, QuickFreeze's purification system requires relatively little maintenance. Out of scope. Has no relevance at all. Wrong Answer

(E)Places, the where the winters are cold rarely have a problem of water on shortage. Out of scope or maybe can even be used to weaken the argument. Wrong answer

Kudos Please... If my post helped.

(A)Bacteria are not the only impurities that must be removed from wastewater.
Makes no impact. On the other hand could be just weakening the weightage of the Municipalities trying to buy the Quick Freeze machines

(B)Many Municipalities have old wastewater Purification Systems that need to be replaced.
Does not help us to justify acquisition of Quick Freeze machines

(C)Conventional wastewater purification systems have not been fully successful in killing bacteria at cold temperatures.
The option which best supports the prediction by showing a limitation in Municipalities which can be fixed by using QuickFreeze machines

(D)During times of warm weather, when it is not in use, QuickFreeze's purification system requires relatively little maintenance.
Does not give Municipalities a reason to buy Quick Freeze systems
(E)Places, the where the winters are cold rarely have a problem of water on shortage.
The statement leads us nowhere.

Moderators, please correct the paragraph. It didn't make sense to me on reading.
