30. Some animals change their color in some climatic conditions. So a scientist observed a bear for a mile from north to south. He tagged it to recognize. Then he travelled along with that from south to north. What is the color of the bear now?
a) Brown b) white c) black d) gray

• No statement gives the idea that scientist started from North pole .
  
  The initial place can be any place on the earth as he has moved only one mile to south.
  
  I think some additional condition is missing.
