Which 1 is an experiment? reading a blood pressure gauge, examining an x ray or taking prescription medicine? Thank you

It would help if you proofread your questions before you posted them.

All can be involved in an experiment, but none of them "is an experiment."

Ok, which of the following is an experiment? A)reading a blood pressure gauge

B)examining an X-ray
C)taking prescription medicine

I didn't think my grammar would effect the understanding of the question...but anyways the question in general is vague so I don't know what to put.

An experiment is a scientific procedure carried out to investigate a specific question or hypothesis. It typically involves testing a particular variable or condition to determine its effect. Out of the options you provided, "reading a blood pressure gauge" and "examining an x-ray" are not experiments because they do not involve changing variables or testing a hypothesis. However, "taking prescription medicine" could potentially be part of an experiment if it is being done to test the effectiveness or side effects of a specific drug. To determine whether taking prescription medicine is an experiment, you would need to consider the specific context and purpose for taking the medicine. If it is being done as part of a controlled study or clinical trial to assess its effects, then it could be considered an experiment.
