Wow this one really got to me. It's amazing how most of my errors spawn from me just not reading closely! "Urban pollution" is not equal to global pollution.

This is the first time that I've seen a video without a comment. So hello.

A 180 and a 177? Talk about a power couple!

Incorrect Premise: Because the city should renovate its train station,

I was also stuck between B and C but ultimately chose B.

C is incorrect because it mistakenly assumes that an employee's general participation in a conversation is the key to improved efficiency, whereas B correctly states that the key to improved efficiency is having an employee participate in generating new ideas.

Conversation participation ≠ idea generation. An employee can participate in a conversation yet provide no new ideas, which would not indicate improved efficiency.
