Information and Ideas practice question
Bamboo looks like a tree but is a grass. Some species grow almost a metre in a single day, and a bamboo grove sends up new stems from one underground network of roots, so what appears to be a forest can be a single connected plant.
Which choice best states the main idea of the text?
- A. Although it resembles a tree, bamboo is a fast-growing grass whose stems can share one root system.Correct
- B. Bamboo is the tallest plant in the world.
- C. Bamboo grows slowly from seeds scattered by the wind.
- D. Bamboo forests crowd out other kinds of plants.
Answer: A. Although it resembles a tree, bamboo is a fast-growing grass whose stems can share one root system.
The text makes three linked points — bamboo is a grass, it grows fast, and its stems are connected underground. Choice A gathers all three.
Why the other answers are wrong
- B. Bamboo is the tallest plant in the world.
- The text says bamboo grows fast, not that it is the tallest plant.
- C. Bamboo grows slowly from seeds scattered by the wind.
- The text describes growth of almost a metre a day, from roots — not slow growth from seeds.
- D. Bamboo forests crowd out other kinds of plants.
- Nothing in the text concerns other plants.
