Final answer:
The recommended test for evaluating the flexibility of the arms and shoulders is the 'Back Scratch Test' or 'Shoulder Flexibility Test', a physical health assessment that involves trying to touch or overlap the middle fingers of both hands behind the back.
Step-by-step explanation:
The test recommended for evaluating the flexibility of the arms and shoulders is not related to Physics, Chemistry, or Biology, but is actually a physical health assessment known as the Back Scratch Test or Shoulder Flexibility Test. This test involves using one hand to reach over the same-side shoulder and down the back while the other hand is reaching up the back from the waist. The goal is to try and touch or overlap the middle fingers of both hands. The results of this test can then provide a good assessment of an individual's upper body flexibility.
