Which term means 'to become smaller'?

• A. Constrict
• B. Contingent
• C. Contraindication
• D. Convulsive

Answer: (A)

The concept here is narrowing or tightening. Constrict describes making something smaller by drawing it in or tightening it, which is exactly how you’d talk about a blood vessel becoming smaller (vasoconstriction) or a belt that constricts around the waist. The idea is a physical tightening that reduces diameter.

The other words don’t fit this meaning: contingent means dependent on something; contraindication is a reason a treatment should not be used; convulsive refers to sudden, involuntary muscle contractions or seizures. None of these convey a reduction in size.
