Which prefix denotes 'less than normal'?

Which prefix denotes 'less than normal'?

• A. Proto-
• B. Olig-
• C. Poly-
• D. Retro-

Answer: (B)

The concept tested is a prefix that signals a smaller quantity or scarcity. Olig- comes from Greek oligos meaning “few” or “scant,” and it is used in medical terms to describe conditions with a reduced amount—for example, oliguria refers to low urine output, and oligomenorrhea to infrequent or scant menses. This direct meaning of “few” fits “less than normal” best. In contrast, proto- means first or early, poly- means many, and retro- means backward. None of those convey a reduced quantity, which is why they don’t fit the prompt.
