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.

(C) Conventional wastewater purification systems have not been fully successful in killing bacteria at cold temperatures

Explanation:

According to the statement, the QuickFreeze’s purification system is a complement to conventional wastewater treatment systems, because it is a system that only kills bacteria at low temperatures. Therefore, municipalities will have to keep their traditional systems for when temperatures aren’t so low.

Let’s consider the different arguments to try to convince the municipality to buy the system:

A) It is an argument that detracts from the need to acquire QF technology since this technology does not control other impurities.

B) It doesn’t help to justify the acquisition of the QF system since this technology it’s not a replacement but a complement.

C) If there are limitations in conventional methods, especially at low temperatures, using the QF system would seem to be an excellent option to kill all bacteria.

D) It is not a strong enough reason to buy it.

E) It is an irrelevant statement.

currents is the correct answer.

i believe it is c: genes for body color and wing size are inherited separately from each parent.
