Using clean-coal technologies to "repower" existing factories promises ultimately a substantial reduction of polluting emissions, and will affect the full range of pollutants implicated in acid rain. The strategy of using these technologies could cut sulphur dioxide emission by more than 80 percent and nitrogen oxide emissions by more than 50 percent. The mission of smaller quantity of nitrogen pollutants would in turn reduce the formation of noxious ozone in the troposphere.

Which one of the following statements is an inference that can be drawn from the information given in the passage.

(A) Sulphur dioxide emissions are the most dangerous pollutants implicated in acid rain.

(B) Noxious ozone is formed in factories by chemical reactions involving sulphur dioxide.

(C) Twenty percent of the present level of sulphur dioxide emissions in the atmosphere is not considered a harmful level.

(D) A substantial reduction of polluting emissions will be achieved by the careful design of new factories.

(E) The choice of technologies in factories could reduce the formation of noxious ozone in the troposphere.

(E) The choice of technologies in factories could reduce the formation of noxious ozone in the troposphere.

A - The passage does not support 'most dangerous pollutants implicated in acid rain'.
B - No where in the passage it is stated that ozone is formed in factories and involves sulfur dioxide
C - There is no information in the passage which tells us what is harmful level of sulphur dioxide
D - This provide an alternate way to reduce pollution. Hence is out of scope of the passage

E - Correct answer. This is a reword of the first sentence

(A) Sulphur dioxide emissions are the most dangerous pollutants implicated in acid rain.

(C) Twenty percent of the present level of sulphur dioxide emissions in the atmosphere is not considered a harmful level.

(D) A substantial reduction of polluting emissions will be achieved by the careful design of new factories.

(E) The choice of technologies in factories could reduce the formation of noxious ozone in the troposphere.

(A) Sulphur dioxide emissions are the most dangerous pollutants implicated in acid rain. -It is not mentioned in the message.The passage says Sulphur dioxide is one of the many pollutants.

(B) Noxious ozone is formed in factories by chemical reactions involving sulphur dioxide.-According to the passage Noxious ozone is formed in troposphere.

(C) Twenty percent of the present level of sulphur dioxide emissions in the atmosphere is not considered a harmful level.We can't infer that since in the passage no such data is mentioned like harmful level of a pollutant.

(D) A substantial reduction of polluting emissions will be achieved by the careful design of new factories.-The passage discuss refitting existing factories with new technology.

(E) The choice of technologies in factories could reduce the formation of noxious ozone in the troposphere.-This looks correct answer.Since the old technology is mainly responsible for pollution,use of new technology will promise a substantial reduction of polluting emissions including nitrogen pollutants which in turn would reduce the formation of noxious ozone in the troposphere.

1) Using clean-coal technologies to "repower" existing factories promises ultimately a substantial reduction of polluting emissions

2) The strategy of using these technologies could cut sulfur dioxide emission by more then 80 percent and nitrogen oxide emissions by more then 50 percent.

3) The mission of smaller quantity of nitrogen pollutants would in turn reduce the formation of noxious ozone in the troposphere.

4) This will affect the full range of pollutants implicated in acid rain. <--conclusion

Which one of the following statements is an inference that can be drawn from the information given in the passage.

(A) Sulfur dioxide emissions are the most dangerous pollutants implicated in acid rain.
-Out.

(B) Noxious ozone is formed in factories by chemical reactions involving sulfur dioxide.
- Can't be derived from argument

(C) Twenty percent of the present level of sulfur dioxide emissions in the atmosphere is not considered a harmful level.
- No.

(D) A substantial reduction of polluting emissions will be achieved by the careful design of new factories.
- Not design, but technology used

(E) The choice of technologies in factories could reduce the formation of noxious ozone in the troposphere.
- This is the one. The argument is about using clean coal to repower factories and goes on to state that reducing emmissions from the factories could affect the full range of pollutants implicated in acid rain. If this is true, then the choice of technologies in factories must be important.

E it is.
