Explanation for C

We know from the passage that some people on the committee are in the construction industry, and many people on the committee work in the suburbs. However, we do not know that there is any overlap between these two! It's completely possible that all of the construction industry professionals work in the city or the country.

Can you please provide further explanation as to why the answer choice is not C? Because I am still confused about how the conclusion was reached and the reason behind why choice (C) was eliminated.

You can't combine quantifiers.

I am also confused regarding C. I understand the concept of not combining quantifiers. However, in this case it is clearly stated none of the PCM live in the suburbs. It is also known that some members have SFI. It doesn't make sense to me that the conclusion of saying nobody with SFI (i.e. some of the PCM) lives in the suburbs is incorrect. E may be better in terms of following the logic paths we learn but I don't see how C is not also a valid choice.

This question is confusing. I thought C would be a better answer. I can see why E is correct and I can see that C is also correct. I need help on this question. Thanks

We have three diagrammable statements: 1) pcm--some--sfi 2) pcm-->not LIS 3) pcm--some--WIS We can only combine the first and second statements and the second and third statements. Combining the first and second statements gets us sfi--some--not LIS Combining the second and third statements gets us WIS--some--not LIS We cannot combine the first and third statements because they're both some statements, and the populations may not overlap. If I say that some people in California like the Rams and some people in California like the 49ers, that does not guarantee that there are some people who like both the Rams and 49ers. This is why we can get rid of C, as it's just trying to combine two "some" statements.
