Why is measurement used in science?

Answer and explanation

Correct answer: To obtain precise and comparable information

Measurement gives a scientific observation a clear numerical value and, where needed, a unit. Instead of saying vaguely that something is large, hot, or fast, a scientist can record a length, temperature, or time. Such information can be checked, repeated, and compared with results from another object or another experiment. Measurement therefore makes observations more precise and supports fair conclusions based on evidence.

Option D is correct because precise and comparable information is the main scientific benefit of measurement. Decoration has no role in collecting evidence, and measurement does not hide guesses or reduce the need to ask questions. A measurement may not be perfectly exact because instruments have limits, but it is still more reliable and useful than an unsupported description.
