What is the main idea?
The main idea of a paragraph is the point of the passage, minus all the details. It’s the big picture – the Solar System vs. the planets. The football game vs. the fans, cheerleaders, quarterback, and uniforms. The Oscars vs. actors, the red carpet, designer gowns, and films.
How to Find the Main Idea
Summarize the Passage
you’ve read the passage, summarize it in one sentence that includes the gist of ever idea from the paragraph. A good way to do this is to pretend you have just ten words to tell someone what the passage was about. You’d have to think broadly, so you could included every detail in just a short statement.
Look for Repetition of Ideas
If you read through a paragraph and you have no idea how to summarize it because there is so much information, start looking for repeated words, phrases, ideas or similar ideas. Read this example paragraph:
A new hearing device uses a magnet to hold the detachable sound-processing portion in place. Like other aids, it converts sound into vibrations. But it is unique in that it can transmit the vibrations directly to the magnet and then to the inner ear. This produces a clearer sound. The new device will not help all hearing-impaired people – only those with a hearing loss caused by infection or some other problem in the middle ear. It will probably help no more than 20 percent of all people with hearing problems. Those people who have persistent ear infections, however, should find relief and restored hearing with the new device.
What idea does this paragraph consistently repeat? A new hearing device. What’s the point about this idea? A new hearing device is now available for some hearing-impaired people. And there is the main idea.
Avoiding Main Idea Mistakes
Now, choosing a main idea from a set of answer choices is different than composing a main idea on your own. The writers get tricky and will give you distractor questions that sound a lot like the real answer! So be sure to avoid making these 3 common mistakes when you’re selecting a main idea on a multiple-choice test.
Finding the main idea can be challenging, but if you use the tools above and practice, you’ll be well on your way to the score you want on the verbal or reading sections of those standardized tests.
