EASY

Assertion : The colourful curtain of green and pink lights in the sky, (which is called "Aurora Borealis") are seen in the polar regions like Alaska and North Canada, but it is not seen in India.

Reason : The earth's magnetic field lines come closer to each other at the magnetic poles, so the charge's density of the charges ejected from the sun, increases near the magnetic poles.
