(a) First half of the month of June
(b) Second half of the month of June
(c) First half of the month of July
(d) Second half of the month of July
Answer: (b)
Option (b) is correct: Since a large portion of the Northern Hemisphere is getting light from the sun, it is summer in the regions north of the equator. The longest day and the shortest night at these places occur on 21st June (i.e. second half of the month of June). At this time in the Southern Hemisphere all these conditions are reversed. It is winter there. The nights are longer than the days. This position of the earth is called the Summer Solstice.
