Concept:An antonym is a word that is nearly opposite in meaning to another word, and this question requires identifying the opposite of the underlined word "escalated."
Explanation:"Escalated" means to increase rapidly or become more intense in degree, amount, or severity.
To answer correctly, find the option that expresses a decrease or lessening of intensity.
Option A, "abated," means to become less intense, severe, or widespread, which is exactly the opposite.
Option B, "increased," means to become larger or greater, so it is a synonym rather than an antonym.
Option C, "proliferated," means to multiply or spread rapidly, which conveys an increase and is therefore wrong.
Option D, "metamorphosed," means to change completely in form or nature, which does not directly oppose escalation.
Thus, the word that is nearly opposite in meaning to "escalated" is "abated."
Answer:A. abated
