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.

Edit: formatted

Snowmaking machine produces mist that freezes immediately and kills bacteria
QuickFreeze is making purification system based on this but it works only in cold temperature.

We need to give a reason why municipalities will buy this inspite of the limitation.

Only option C tells us the reason by saying that the conventional methods do not work in cold environment
Hence QuickFreeze can fill the gap.

Correct Option: C

A and C should be contenders.

C strehthens the argument more than snow making machines are req.

A talks about diff types of impurities which is not relevant to the argument

"C" is the correct choice - QuickFreeze plans to market wastewater purification systems that works by spraying a mist that freezes on contact with cold air. The sudden freezing kills bacteria. Because the system works only at cold temperatures, municipalities using it will still need to maintain a conventional system.

Prethinking: Municipalities would want to kill bacteria in summers as well as winters. If they invest in Quickfreeze, knowingly that they will be required to maintain conventional systems as well. The only basis will be that the conventional system is ineffective in cold weathers.

(A) Bacteria are not the only impurities that must be removed from wastewater.

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

This is a strengthen the argument question.
Like weaken, strengthen questions also require us to isolate the conclusion. As we will be looking for the answer that makes our belief stronger on the premise-conclusion relationship such as analogies, survey, reports, statistical data etc.
Protect the missing information
a) by keeping any option that fills the gap
b) by eliminating the answer that attacks the missing information

Conclusion: municipalities will buy QuickFreeze's purification system.

Why will they buy something that has a drawback? Because QuickFreeze's purification system must have something that the conventional system doesn't have.

C, here, talks about the drawback that conventional purification system has. So, if both purification systems work together, it can solve the problem. C is our answer.

(A) Bacteria are not the only impurities that must be removed from wastewater. Even if there are other impurities whether existing conventional purification system is able to counter or not is not relevant as we need for strengthener something which provides us with the reason what extra benefit Quick Freeze purification system is able to provide. So in nut shell not affecting the argument at all

(B) Many municipalities have old wastewater purification systems that need to be replaced.It does not provides us with the reason of why we need Quick Freeze purification system. It does not strengthens the argument

(C) Conventional wastewater purification systems have not been fully successful in killing bacteria at cold temperatures.CORRECT as conventional system does not works in winter...Hence we would require Quick Freeze purification system additionally

(D) During times of warm weather, when it is not in use, QuickFreeze's purification system requires relatively little maintenance.- Out of Scope as we are not concerned with the maintenance cost here

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

Edit: formatted

Question Type: Strengthen

Premise 1: Since sudden freezing kills bacteria, Quickfreeze, is planning to market a waste water purification system, that works on the principle of snow making machines.

Conclusion: Municipalities planning to use quick freeze will still have to maintain their conventional systems, as quick freeze works only in cold temperatures.

Analysis: Since the question is asking to strengthen this decision taken by the municipalities, there needs to be a compelling reason for them to bear the additional cost of Quick freeze in addition to conventional systems. Either Quickfreeze provides a benefit which it does since it kills bacteria at cold temperatures, which conventional systems may or may not or in cold temperatures due to harsh weather conditions Quickfreeze is an easier method to deploy than conventional systems. The correct answer needs to support the use of quick freeze in winters despite conventional systems still being operational.

(A) Bacteria are not the only impurities that must be removed from wastewater. - Hence the simultaneous requirement of conventional system, however does not strengthen the need for Quick freeze, Incorrect

(B) Many municipalities have old wastewater purification systems that need to be replaced. - Argument does not say about anything replacing conventional system. Incorrect.

(C) Conventional wastewater purification systems have not been fully successful in killing bacteria at cold temperatures. - Hence at Cold temperatures the municipalities need an alternate method to kill this bacteria, therefore Quick freeze is required. Perfect. Correct

(D) During times of warm weather, when it is not in use, QuickFreeze's purification system requires relatively little maintenance. Not enough a compelling reason to use quick freeze. Incorrect

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

Thanks,
