The sun’s rays can be vertically overhead only up to 23½° north and south latitudes because
Answer: D
Because the earth's axis is inclined at 66½° to the plane of its orbit.
That inclination is the same as a tilt of 23½° from the vertical, so as the earth revolves the vertical rays move only between 23½°N and 23½°S. Those two limits are the Tropics of Cancer and Capricorn, and the tilt is also what gives us the seasons.

Which is the longest river flowing entirely within India?
Answer: A
Correct answer: The Godavari
The Godavari, about 1,465 km long, is the longest river whose entire course lies within India. It rises at Trimbakeshwar in Maharashtra and flows east across the Deccan through Telangana and Andhra Pradesh to the Bay of Bengal, where it forms a large delta. It is often called the Dakshina Ganga, the Ganga of the south. The Ganga is longer at about 2,525 km but flows into Bangladesh before reaching the sea, so it does not qualify. The Brahmaputra rises in Tibet as the Yarlung Tsangpo and also crosses into Bangladesh; the Indus rises in Tibet and flows chiefly through Pakistan. The Godavari is the second longest river in India after the Ganga, and its basin is the largest of the peninsular rivers. Its major tributaries are the Pravara, Manjira, Indravati and Sabari, and the Polavaram and Sriram Sagar projects are built on it.

Which state is the largest producer of coal in India?
Answer: B
Correct answer: Jharkhand
Production ranks vary a little from year to year between the leading states, with Jharkhand, Odisha and Chhattisgarh all major producers; Jharkhand holds the largest reserves and has historically led output. India’s coal lies almost entirely in the Gondwana rocks of the eastern peninsula, laid down some 250 million years ago, and it is concentrated in the Damodar valley - Jharia, Bokaro, Raniganj and Karanpura - along with the Mahanadi and Godavari basins. Jharia is India’s most important coking-coal field, and the only substantial one, which is why it matters to the steel industry; a coal-seam fire has burned there since 1916. Most Indian coal is bituminous with a high ash content, which is why coking coal is imported despite large domestic reserves. Anthracite occurs only in small quantities in Jammu and Kashmir. Coal supplies the largest share of India’s electricity.
