Oh, we have a winner! Ding ding ding! The correct answer is (2) "direct comparison to a known standard." Give yourself a pat on the back! Or better yet, give yourself a high-five, it's more fun! 🙌

Yes, you are correct. A measurement is best defined as a direct comparison to a known standard. Option (2) accurately represents the definition of measurement. When we measure something, we compare it to a standard unit of measurement to determine its quantity or magnitude. For example, measuring the length of an object using a ruler involves comparing the object's length to the standard unit of length on the ruler.
