Which term means 'weakness'?

• A. asth
• B. -ase
• C. asthenia
• D. aur

Answer: (C)

The idea being tested is how medical terminology uses a root with a suffix to express a symptom or state. The root asthen- means weakness or lack of strength. When you add the suffix -ia, it forms a noun that names a condition. Put together, asthenia is the medical term for a state of weakness or generalized fatigue.

So why this one fits best: it literally translates to a condition of weakness, which is exactly what the question is asking for. The other fragments aren’t used to denote weakness on their own: asth isn’t a stand-alone term for a condition, -ase is a suffix that names enzymes, and aur- is a root related to the ear or the element gold in some terms, not a state of weakness.
