I can guarantee that the "measure the height of a building with a
barometer" question with its unexpected answers was around at least in
1966, when my high-school Physics teacher distributed a mimeographed
copy to the class.  I didn't keep it (or if I did, I don't know where
to find it).  My favorite answer was the one about trading the barometer
for the required info.  Other answers:  time how long it takes to fall
from the top of the building; tie it to a string, lower it from the roof
and measure the length of the string; swing it from a string and time
the period of the pendulum; measure it with a ruler and measure the
building with it; and measure it, its shadow, and the building's shadow
with a ruler and triangulate.
