IREAD - Indiana Reading Evaluation and Determination Nonfiction: Main Idea & Details Questions and Answers

Question 1

Read the paragraph below.

Giraffes are the tallest mammals on Earth. Their long legs and necks help them reach leaves high up in trees, which are their favorite food. A giraffe's coat has a unique pattern of spots, much like a human's fingerprint. These spots help them blend in with their surroundings to hide from predators. Even with their great height, giraffes can run very fast when they need to.

What is the main idea of this paragraph?

Accepted Answer

Giraffes are tall mammals with special features.

Answer

The correct answer is that giraffes are tall mammals with special features. The other sentences are supporting details that describe these features, such as their height for reaching food, their spot patterns for camouflage, and their speed. The main idea is the most general statement that all the other sentences support.

Question 2

A student is reading a chapter in a science book about planets. The first sentence of a paragraph is: 'Mars is often called the Red Planet.' Which of the following sentences would MOST likely be a supporting detail in this paragraph?

Accepted Answer

The soil on Mars is red because it contains iron oxide, or rust.

Answer

The main idea introduced in the topic sentence is about Mars being called the 'Red Planet'. A supporting detail will give more information about this main idea.
