Both are strong as both will affect us directly or indirectly.

As both the options will reduce pollution at one level and increase at other level of the atmosphere, both the options are strong arguments to one another rather than the Main statement. So, I think neither of them are strong arguments and would go with option D

We can't go with both statements here. I know both statement are strong but both statement is contradictory to each other. So in my opinion C is correct option.

Ya its right in case of upper atmospheric level it giving support to us and this because of this pollution global worming also increase side by side is alter the rain pattern of global.

If we operate chimney in upper atmosphere leads to holes in ozone layer as well as harmful for birds.
Trishul said:   1 decade ago
Adding to others point, my understanding is that while low chimneys concentrates pollutants to some areas at ground level, high chimneys disperses those pollutants over a much larger area and they eventually settle down to the ground. Clearly both have their pros and cons.

For me Option C is right.

Both argument are strong. Definitely long chimneys will reduce pollution at ground level, on the other hand it will significantly pollute upper environment, and eventually toxic in the form of rain will show it's hazardous effect.

In the thermal power plant it should be noted that the height of chimney is considerable at a constant height not to be bigger so that it causes the atmospheric press high.

So 2 statement is not correct I think 1 be the best option A.

If the smoke is released at upper atmosphere. It will eventually deplete the environment at ground level. Pollution will deplete the entire atmosphere. So, Shouldn't B be the answer ?
Anand pandey said:   9 years ago
The answer is C because the chimney is also polluted upper atmosphere which directly impacted on the ozone layer.
