"Core"? Seriously?

Which of these statements are true:

A) Is it impossible for an end user or business (i.e. non-ISP) to get a direct connection to a "Tier 1" (whatever the hell that means) provider.
B) Most traffic on the Internet traverses Tier 1s today.
C) A Tier 1 has a different profit motive than a Tier 2 (whatever the hell that means) providers.
D) All Tier 1 providers are larger than all Tier 2 providers.

We'll just skip over the E) all of the above.
