Question

Which of the following identifies a measurement, its SI unit, and the tool most commonly used to measure it?
	A.	length, meter, ruler
	B.	temperature, degrees Fahrenheit, thermometer
	C.	weight, gram, scale
	D.	volume, millimeter, meniscus

Mercury · Answer

using process of elimination:

eliminate B (Fahrenheit is not an SI unit. SI for temperature would be Kelvin)
eliminate C (grams are a measurement of mass not weight)
eliminate D (milimeter is not a measure of volume)

therefore the only possible solution is A (SI unit of length is meter, which can be measured using a ruler)
