Explanation:

• Question 199: Myopia (nearsightedness) is corrected with concave lenses as they diverge light rays. Presbyopia (age - related farsightedness) is corrected with convex lenses as they converge light rays. Emmetropia is normal vision. Diplopia is double vision.
• Question 200: A thrill is an abnormal heart sound that can be felt as a vibration. A gallop is an abnormal heart rhythm sound. A rub is a sound due to friction (e.g., pericardial rub). A rumble is a type of heart murmur sound but not specifically a vibration - felt sound.
• Question 201: Gout is caused by the buildup of uric acid crystals in the blood and joints. Lithosis refers to the formation of stones (e.g., kidney stones). Uricase is an enzyme. Exostosis is an abnormal bone growth.

Answer:

• Question 199: myopia; presbyopia
• Question 200: thrill
• Question 201: gout
