How is number 8 right? It says they are teachers of that particular occupation not actually part of the profession.

I thought it was A because the narrow floorboards surviving would make them better quality, hence why they were a status symbol for the wealthier houses. I don't understand why this is wrong reasoning.

This was exactly my reasoning too and I’m unsure why it’s wrong.

Literally

yeah like i definitely saw the issue with A when choosing it. however i still felt like it was the best choice because i never realized the comparison trick he used. :(

also felt like negating the other answers worked too...

I love your comments

I'm thinking of it like:

That doesn't make sense to me and thus I'm thinking it is not an argument.

Any thoughts?

I'm having the same struggle
