"Tryst With Destiny" seems to be dropped pretty early for Nehru. I really am nowhere near an expert (or even all that knowledgeable) about him, but that's a pretty recognizable thing right there early in the question.

EDIT: can't type

7/53/3 in 70 rooms, which is a very normal conversion rate.

Hey Jeff, would you mind posting the comp card system bonus. Also, what was the rationale behind that question?

HSNCT round 21 wrote:Pencil and paper ready. Consider a 256-team, power-matched quiz bowl tournament. For 10 points each--

A. If in every round each team played against an opponent with the same record, how many teams would still be undefeated after 5 rounds?

answer: _8_ teams [256/(2^5^) = (2^8^)/(2^5^) = 2^3^ = 8]

B. If in every round each team played against an opponent with the same record, how many teams would have a winning record after 7 rounds?

answer: _128_ teams [With an odd number of games played, no team would be at exactly .500, so exactly half the teams would have a winning record.]

C. If each team played 9 games, but the tournament lasted 12 rounds, then what is the minimum number of game rooms that would be required? Assume each game features exactly 2 teams.

answer: _96_ game rooms [With no byes at all, it would require 256/2 = 128 game rooms; 128 x (9/12) = 128 x (3/4) = 32 x 3 = 96]

While watching the finals, I think there was a question about T cells which lead in with something along the lines of "these types of cells are helped by the major histocompatibility complex" - I feel like the answer at that point could also be any antigen presenting cell because the MHC does in fact "help" the APCs (i.e. dendritic cells, B cells) by allowing them to present the antigens on their cell membranes. Could you please post that question?

Major histocompatibility complex class I molecules work to aid these cells. Like natural killer cells, one group of them releases the protein perforin, and these cells express glycoproteins (*) CD4 and CD8. Produced in an organ lying between the lungs, they have "helper," "memory," and "cytotoxic" varieties. For 10 points--name this type of white blood cell whose one-letter name suggests its origin in the thymus.

answer: _T_ cell or _T_ lymphocyte (prompt on "white blood cells" or "lymphocytes" before "thymus"; accept _cytotoxic T_ cells or _cytotoxic T_ lymphocytes before "CD4"; prompt on "Tc cells" before "CD4")

While what you said was true about the MHC, it looks like MHC Class I interacts with T cells only.

Ah yeah that makes it less ambiguous. I guess if someone really wanted to be a pain in the neck they could buzz in and say "all cells with a nucleus" because MHC Class 1 is expressed by all nucleated cells to present antigens to T-cells...

Sorry to revive an old thread, but where can one find the audio recordings of the tournament?

Is there a list of what teams are playing in each of the games on the audio recordings?

Game 6 was Fisher Catholic vs North Kansas City

If I'm correct, I believe all the games that were recorded were in Mike Bentley's room.

Speaking of this, did the recordings from ICT ever find their way onto the internet?
