Come on Val! It can't be so bad, I did not even have to do the integration! I could have made it much worse!!!

An explorer decides to test his latest acquisition, a new fangled GPS with bells and whistles which, using 24 satellites, reports his location on earth to within a few meters . To test it he walks South for 15 km. At this point he suddenly sees a bear and decides wisely to move in a different direction hence he now walks West for 15 km. He then walks North for 15 km and, amazingly, finds himself where he started from originally.

What is the colour of the bear?

[mAKi]

same color as the sports car hidden behind the door A or B

there is no bear with all this noise

Wrong, the sports car is red!!!

there is no bear with all this noise

You may be right but this would be due to climate change, not noise!

Try harder, this is an easy one!

[mAKi]

ah ah if it is not his shadow that he sees and that there is really still a bear in this place, it's surely a polar bear, so the bear is white

[limelight]

Correct. He left from the north pole, and after his trip, he was back at the north pole. The bear is indeed white.

The same explorer as in puzzle 6 has now moved to a far away continent where he knows bears don't exist.

Still not satisfied that his GPS is working correctly, he repeats the test (eg South for 15 km, then West for 15 km, then North for 15 km) and, amazingly, he finds himself again where originally he started from. The only living creature which he has ever seen on this continent is a large bird, the male of the species seemingly spending a lot of time trying to hatch the egg laid by the female by holding the egg between the top of its feet and its lower abdomen.

What is the name of the bird species?

[mAKi]

too easy



it's only at the poles that one can find oneself at one's starting point in this way, and now your explorer is in antarctic

[limelight]

Correct, he must have been 15 km north of a parallel that was exactly 15 km in circumference ( or 7.5 km, or 5km ...), so he went south 15 km, landed on that parallel, walked full circle around the pole, and landed where he started from after trekking 15 km north.
