Now fourth, and hopefully last, problem, subtly different from the first three:
Imagine standing at the North Pole of the Earth.
Walk in any direction, in a straight line, for 1 km.
Now turn left so as to face East.
Walk towards the East for as long as it takes to pass near the point where you turned.
Not counting the initial 1km, have you walked;
1. More than 2xPi km
2. Exactly 2xPi km
3. Less than 2xPi km
4. I never came close to my starting point.
Think about how you tried to answer this question and tell us whether it was based on language.
