Detail and Main Idea Questions

Main idea questions and fact or detail questions are both asking you for information that's right there in the passage. All you have to do is find it.

Detail or Fact Questions

In detail or fact questions, you have to identify a specific item of information from the text. This is usually the simplest kind of question. You just have to be able to separate important information from less important information. However, the choices may often be very similar, so you must be careful not to get confused.

Be sure you read the passage and questions carefully. In fact, it is usually a good idea to read the questions first, before you even read the passage, so you will know what details to look out for.

Main Idea Questions

The main idea of a passage, like that of a paragraph or a book, is what it is mostly about. The main idea is like an umbrella that covers all of the ideas and details in the passage, so it is usually something general, not specific. For example, in Practice Passage 1, question 3 asked you what title would be best for the passage, and the correct answer was "Community Policing: An Uncertain Future?" This is the best answer because it's the only one that includes both the positive and negative sides of community policing, both of which are discussed in the passage.

Sometimes the main idea is stated clearly, often in the first or last sentence of the passage. The main idea is expressed in the last sentence of Practice Passage 1, for example. The sentence that expresses the main idea is often referred to as the topic sentence.

At other times, the main idea is not stated in a topic sentence but is implied in the overall passage, and you will need to determine the main idea by inference. Because there may be much information in the passage, the trick is to understand what all that information adds up to—the gist of what the author wants you to know. Often some of the wrong answers on main idea questions are specific facts or details from the passage. A good way to test yourself is to ask, "Can this answer serve as a net to hold the whole passage together?" If not, chances are you have chosen a fact or detail, not a main idea.

Practice Passage 2: Detail and Main Idea Questions

Practice answering main idea and detail questions by working on the questions that follow this passage. Circle the answers to the questions, and then check your answers against the key that appears immediately after the questions.

There are three different kinds of burns: first degree, second degree, and third degree. It is important for firefighters to be able to recognize each of these types of burns so that they can be sure burn victims are given proper medical treatment. The least serious burn is the first-degree burn, which causes the skin to turn red but does not cause blistering. A mild sunburn is a good example of a first-degree burn, and, like a mild sunburn, first-degree burns generally do not require medical treatment other than a gentle cooling of the burned skin with ice or cold tap water. Second-degree burns, on the other hand, do cause blistering of the skin and should be treated immediately. These burns should be immersed in warm water and then wrapped in a sterile dressing or bandage. (Do not apply butter or grease to these burns; despite the old wives' tale, butter does not help burns heal and actually increases chances of infection.) If second-degree burns cover a large part of the body, then the victim should be taken to the hospital immediately for medical care. Third-degree burns are those that char the skin and turn it black, or burn so deeply that the skin shows white. These burns usually result from direct contact with flames and have a great chance of becoming infected. All third-degree burns should receive immediate hospital care. They should not be immersed in water, and charred clothing should not be removed from the victim. If possible, a sterile dressing or bandage should be applied to burns before the victim is transported to the hospital.
