Main Idea worksheet featuring three short passages with comprehension questions for students.

Let's solve each question by identifying the main idea of each paragraph. The main idea is the central point or most important message the author wants to convey.

Question 1:

Paragraph:
*Mushrooms don't grow on trees. If you see mushrooms stuck between the branches, you know they were put there. Most likely it was the work of a red squirrel. Red squirrels like mushrooms. They like to put them in trees. Then they have food to eat in the winter.*

Options:
a. Why there are mushrooms in trees
b. Why squirrels like mushrooms
c. Where to grow mushrooms

✔ Correct Answer: a. Why there are mushrooms in trees

Explanation:
The paragraph explains that mushrooms aren't naturally growing on trees but are placed there by red squirrels for food storage. So, the main idea is explaining why mushrooms are found in trees — because squirrels put them there. Option (b) is too narrow (only about why squirrels like mushrooms), and (c) is incorrect because the text doesn’t tell us how to grow mushrooms.

Question 2:

Paragraph:
*It's a salty world in which we live. There is salt in the ocean. There is salt in the earth. There is salt inside you—in your blood, in your sweat, and even in your tears. It's a good thing too. Without salt you couldn't live.*

Options:
a. How salty the world is
b. What salt is like
c. Why people use salt

✔ Correct Answer: a. How salty the world is

Explanation:
The paragraph emphasizes that salt is everywhere — in the ocean, earth, and even in our bodies. The key message is that salt is present throughout the world and is essential for life. While option (c) might seem plausible, the focus isn’t on *how* people use salt, but rather on its presence in nature and the body. Option (b) is vague and not the focus. So, the best choice is (a) — it captures the overall idea that salt is widespread.

Question 3:

Paragraph:
*Do you know why snakes stick out their tongues? They use their tongues to pick up smells and to feel things. The snake’s tongue is not a stinger as many people think. The snake is just touching and smelling the world with it.*

Options:
a. Why snakes bite people
b. Why snakes stick out their tongues
c. What snakes eat

✔ Correct Answer: b. Why snakes stick out their tongues

Explanation:
The entire paragraph answers the question posed at the beginning: “Why do snakes stick out their tongues?” It explains that they use their tongues to smell and feel things, and clarifies a common misconception. Option (a) is irrelevant (no mention of biting), and (c) is not discussed. So, the main idea is clearly (b).

✔ Final Answers:

1. a. Why there are mushrooms in trees
2. a. How salty the world is
3. b. Why snakes stick out their tongues

These choices best summarize the central idea of each paragraph.
