C is wrong because we cant conclude that the sample will be the same for the second questionaire.

Both concerns are similar, so the responses should be.

I will go for D as it says response rate The response rate of one questionnaire can be predicted from the other.

C may not be correct as it talks about people's concern, as the number of respondents may be more than the number of people concerned.

Amardeep

Chose D. We have no information available which can support other options.

The Group can project the response rate for air pollution survey only if it assumes that result of a past survey can be extrapolated to calculate response rate for new surveys. All choices other than D are either outside scope of argument or supply redundant information

Hence D

Give me D!

It doesn't matter if the people who are concerned about ocan dumping are even more concerned about air pollution. they still get only one questionnaire to respond to!

the concern of people in C doesn't necessarily mean they will be responding to the survey or even that set of people would be taken in for the survey.
