question 209

o having lethargy
o moving backwards

question 210
the medical term opto/metr/ist literally means:
o a specialist in sight management
o a specialist in the eye
o a specialist in eye diseases
o a specialist in measuring sight

Explanation:

• Question 208: The cochlea is a spiral - shaped organ in the inner ear that is responsible for hearing. The labyrinth (which includes the semicircular canals, utricle, and saccule) is involved in balance. The malleus is one of the ossicles (tiny bones) in the middle ear, the eustachian tube equalizes pressure between the middle ear and the environment, and the incus and stapes are also ossicles.
• Question 209: The Latin word “deprimere” means “to press down”. “Depression” in the medical/psychological sense can be thought of as a “pressing down” of mood. “Sadness” is an emotion related to depression but not the etymological root. “Having lethargy” and “moving backwards” are not related to the etymology of “depression” from “deprimere”.
• Question 210: Breaking down the word “Opto/metr/ist”: “Opto -” relates to sight, “- metr -” relates to measuring (like in “meter”), and “- ist” means a specialist. So, an optometrist is a specialist in measuring sight. An ophthalmologist is a specialist in the eye (including eye diseases), and “a specialist in sight management” is too vague compared to the etymological breakdown.

Answer:

• Question 208: C. cochlea; labyrinth
• Question 209: B. to press down
• Question 210: D. a specialist in measuring sight
