Many people think of deserts as lifeless. The Thar tells a different story. After the brief summer rains, grasses cover the dunes within days, and herders bring their animals to graze. Seeds that have waited in the sand for years sprout at once. The desert is not dead; it is waiting.
The main purpose of the passage is to
A. describe how herders live in the Thar
B. correct the belief that deserts are lifeless
C. explain why so little rain falls in the Thar
D. argue that deserts hold more life than forests
- The passage opens with a common belief ('deserts as lifeless') and turns at once: 'The Thar tells a different story'.
- The grasses, the grazing animals and the sprouting seeds are all evidence against that belief, and the last sentence states the point: 'The desert is not dead'.
- A is too narrow (herders are one detail). C is not discussed. D is too strong: forests are never mentioned.
- Only B covers the whole passage and matches what the author does.
Answer: B. correct the belief that deserts are lifeless
