Hi,

I was not sure about E...the language is so confusing.
How should I understand the answer choice and why is it wrong?

Thanks in advance!

The "sizable subgroup" this ac refers to (in lawgic terms) would be /M --> /C . Which is actually the contrapositive of the scientists conclusion C --> M . But... the idea that the reporter presumes anything like there not being a "sizable subgroup" simply doesn't happen. It is totally irrelevant. What would "sizable" even constitute?
