bold, followed by three sentences using that word. The word may be used correctly or incorrectly in each sentence. Select which sentence(s) use the word correctly by marking the option that corresponds to your answer. Word: Pernicious I) The pernicious weed spread quickly and destroyed the crops. II) His pernicious smile made everyone feel welcomed and happy. III) The pernicious effects of pollution are visible in the city’s poor air quality.Solution
• I) The pernicious weed spread quickly and destroyed the crops. This sentence correctly uses "pernicious" to describe something that is harmful or destructive. A weed that destroys crops is indeed pernicious. • III) The pernicious effects of pollution are visible in the city’s poor air quality. This sentence is also correct. "Pernicious" accurately describes the insidious and damaging effects of pollution on a city's environment. • II) His pernicious smile made everyone feel welcomed and happy. This is an incorrect use of the word. "Pernicious" has a negative connotation, meaning something that is harmful or has a very damaging effect, often in a gradual or subtle way. A smile that makes people feel "welcomed and happy" is the opposite of pernicious.
