Which term means 'to make impure'?

• A. Analogous
• B. Adulterate
• C. Aggrandize
• D. Abscond

Answer: (B)

The main idea here is identifying a verb that describes making something impure. The word that fits this meaning is adulterate. It means to contaminate or dilute something by adding another substance, reducing its purity—think of adulterating food or medicine.

Other options don’t capture impurity: analogous means similar or comparable, not about purity. Aggrandize means to increase appearance of power or greatness, often by praise, not about contamination. Abscond means to flee secretly, especially to avoid punishment, which is unrelated to purity.
