Without numbers for other, well known sensors, using the same
methodology, that number is meaningless to me. Even translated into
stops, it's still of limited use without reference points. In fact, it's
the performance of the sensor system as a whole that matters, not the
sensor alone. Flawed as they may be, DSPR's dynamic range tests clearly
illustrate this, especially in the effect of shadow noise on effective
range.
I'll stick with my original answer, which is actually useful to a
photographer.

I figured this was a trick, and could have gotten it correct using test
taking psychology, but chose not to. Since 6 is entirely dependent on 5,
I'm counting this as one wrong.

Stretching a point here - quite far.
Sooo... I'll call 1 a correct for me, as your answer, while technically
correct, is useless, and mine, while unquantified, is actually useful
and accurate.
On 2-4, my answers were correct. 4 for 5 gives me 80%.
