A friend of yours has bought a lovely 150-year-old farmhouse in rural Maryland. The water in the house comes from a recently dug well. She is concerned with the purity of the water, especially given the very high content of iron in the area. Iron is not considered toxic, but it can be unpleasant in drinking water and cause other problems (stains, clogging, odors, etc.) in a home's water system. The recommended limit for iron in a home is 0.3 milligrams per liter (mg/L). Your friend has purchased a testing kit that she uses to test a sample at 11:30 every Friday morning. The sample returns a single current value of iron (e.g., 0.37) in the household water system. She then takes the resulting value and places it on a graph in Excel, with dates (Fridays over the year) on the x-axis and mg/L on the y-axis. Which of the following is true for the scenario?

Group of answer choices

A. mg/L is the metric, the graph contains measures, and the testing on Friday morning is measurement

B. mg/L is the metric, the graph contains measurement, and the testing on Friday morning is measures

C. mg/L is the measurement, the graph contains measures, and the testing on Friday morning is a metric

D. 0.37 mg/L is the metric, the graph contains measures, and the testing on Friday morning is measurement

E. None of the above
