MCQ practice · SSC Bangladesh and Global Studies Board questions · Chapter 3: The Solar System and the Earth
The months in which day and night are equal on the Earth-
- i. March
- ii. June
- iii. September
Think it through first, then pick an option.
- a i and ii
- b i and iii
- c ii and iii
- d i, ii and iii
Answer and explanation
Correct answer: b i and iii
The book says on 21 March and 23 September day and night are equal everywhere on the Earth.
Why the other options are wrong
- a i and ii: ii is false: in June (21 June) the day is longest in the north; day and night are not equal.
- c ii and iii: This leaves out i and includes the false ii: 21 March also has equal day and night; 21 June does not.
- d i, ii and iii: ii is false: day and night are not equal on 21 June, so not all three are true.
