What Are Command of Evidence Questions?

Command of Evidence Questions are part of the SAT Writing and Language Test. They ask you to improve a passage by adding information or ideas based on evidence. You may be asked to select details that strengthen arguments or add informative details to a passage.

Sample Command of Evidence Questions

To give you a better understanding of what to expect from Command of Evidence questions on the SAT Writing and Language Test, let's take a look at a sample passage and a couple of sample Command of Evidence questions.


Most people are surprised to find that their diets are full of hidden sugar. There are added sugars hiding in yogurt, cereal, tomato sauce, salad dressing, and even bread. Parents are often shocked to find that the so-called healthy, whole-grain cereal and low-fat milk they serve their children in the morning can contain a whopping 30 grams of sugar. This is more sugar than the American Heart Association recommends an adult consume in an entire day. Parents are sending their children out the door on a sugar high, and when the children get to school, they are likely to crash.

While some sugar is naturally occurring, such as the sugar found in fruit, the added sugars are the real problem, and likely the culprit of the obesity epidemic in America today. Studies have suggested that higher intake of added sugar is associated with cardiovascular disease risk factors. A Harvard Study found that drinks with added sugar increase the risk of obesity and diabetes, and both portion size and consumption has risen dramatically in the last 40 years. Sugar intake must be reduced in order to lower obesity rates.

Passage Questions

Now that you've read the passage, try answering these questions.
