• Understanding the Bracketed Word: The word given is Enlarge, which means to make something bigger, increase, or expand.
The Context of the Sentence: The sentence mentions a "new law" regarding "illegal drugs." Laws are generally created to stop, reduce, or limit illegal activities, not to make them bigger.
Why "Curtail" is the Antonym: Curtail means to reduce in extent or quantity; to impose a restriction on. Since the opposite of "enlarge" (increasing) is "curtail" (decreasing/restricting), it is the most appropriate antonym for this context.
