III. Reading Comprehension 30% A. New driving glasses contain sensors embedded in the frame to measure how often eyelids blink and how much they droop between blinks. Sensors translate this into a “drowsiness score” shown on the dashboard and deliver an auditory warning when scores exceed safe limits. Designed for commercial drivers, the glasses may be available for regular drivers within the next two years. 26. If the article needed a title, which would be BEST?

B. Diabetics, put away the bandages: A new technique for checking blood sugar could make finger pricks a thing of the past. Chemists from Northeastern University have developed a method for injecting tiny fluorescent sensors under the skin that detect glucose in the blood. Take a picture of the freckle-size temporary tattoo with a special attachment that fits over your smart phone’s camera lens, and a computer program then analyzes the photo and reports your blood sugar number. The tattoo method is still under-going tests; it could be available in three years.  27. If the article needed a title, which would be BEST?
