Question

1. indifferent : detached :: ______

a. prefix : suffix
b. informal : casual
c. network : connected
d. respectable : dishonorable

Explanation:

First, analyze the relationship between "indifferent" and "detached"—they are synonyms (both mean showing little interest or being emotionally distant). Now check each option:

• Option a: "prefix" and "suffix" are different types of word parts, not synonyms.
• Option b: "informal" and "casual" are synonyms (both refer to a relaxed, non - formal style), matching the synonym relationship of the given pair.
• Option c: "network" is a noun and "connected" is an adjective, and they are not synonyms.
• Option d: "respectable" (deserving respect) and "dishonorable" (not honorable) are antonyms, not synonyms.

Answer:

b. informal : casual
