8th Grade Spring 2025 Semester Exam Review

According to the passage, what is the relationship between an algorithm and a computer program?

• An algorithm is the opposite of a computer program.

• Every algorithm is also a computer program.

• A computer program is an example of an algorithm.

• An algorithm is the language in which a computer program is written.

What is the meaning of the word "sequence" as it is used in the passage above?

• A. To arrange in a particular way

• B. The order in which things happen

• C. A later development

• D. A set of related events

When are algorithms most useful? Well, algorithms provide solutions that work every time. You wouldn't use an algorithm for something you only need to do once. But, if the same kind of problems keeps coming up, an algorithm may prove very useful. For instance, you've likely had to add two digit numbers many times in your life. After solving enough of these kinds of problems, you probably identified and memorized the steps you were following. Now, when you need to find a sum, you don't need to come up with a unique solution; you have a solution that works every time. Computer programs, algorithms that computers follow, are useful in the same way. For example, Pixar, a computer animation studio, might use an algorithm for adding color based on lighting in a scene.

• Pixar animations usually do not include shadows.

• Pixar only uses algorithms for one off tasks.

• In creating scenes, Pixar frequently has to add color based on lighting.

• The color in Pixar movies is often too bright and unrealistic.
