Re: [APD] Re: CO2 Reactor Quiz -- Scoring and Answers

Unforturnately, I don't remember all that well the pic of
this reactor without the bioballs blocking the internal

Excellent guess -- however, since it is considered by the
judges to be obviously implied by the question, they grant
on 5 points

"No" is the correct answer -- one can't tell beans about
the waterflow from this pic.  However, extraneous info
following the "No" detracts from your score ==> 
 10 points - 5 pts ==> 5 points

Sorry. "No" is the correct answer. Although you followed
the firss part of the path through what must be the world's
unnecessarily longest bubble counter, who knows what goes
on inside the reactor -- the pic doesn't show.

> > Can you follow the CO2 from start to end?

Interesting you provided two answers to one question. Not
quite kosher, but let's see how you did with each. 

> "All things that have a beginning... have an end"

Tell that to the infitinely-expanding-big-bang theorists.
Besides, one of the judges is a Neo-Euchlidian and was
downright put out by this answer.

Actually, it looks like you tried to slip in a third answer
there at the end that would cover all bases. But the 2nd
answer was considered almost as complicated as the device
so the judges awarded 2 points for showing a lot of
something they call Farfellnugen). 

Btw, the correct answer was "E - None of the above" -- It's
the right answer at least once in every quiz!

Now we have an answer to a question that wasn't even in the
quiz. Bonus points = 0 (remember, there *was no* Bonus

One can't tell much from this pic.  Possibly a tube runs
down the center through the dock and and all the way to the
deep blue sea.

Come to think of it, this is a darn lousy pic upon which to
base a purchasing decision.

At today's exchange rates for Euros into US Dollars, you
need only $196.01 plus shipping to get one of these
incomparable beauties in your house -- Or, if you had
scored just one more point in the quiz, the whole thing
would have been on me.

But don't be discouraged -- try again next month when we
take a quizzical look at the world's most overengineered 
aquarium substrate - or what Uncle Albert used to call
"Dieser verfluchte dumme Schichtkuchen."
