Step 1: Understanding the Concept:
Synonym matching exercises test your command of vocabulary by requiring you to align words with their precise semantic definitions. Identifying a single definitive match can often help you eliminate multiple incorrect options at once.
Step 2: Detailed Explanation:
Let's find the exact meaning for each word in Column I:
1. Eloquent: Describes someone who is vivid, articulate, moving, and expressive in speech or writing. This perfectly matches definition P (Fluent or persuasive in speaking).
2. Vivacious: Derived from the Latin root vivere (to live). It describes a person who is attractively lively, animated, and high-spirited. This matches definition R (Lively, animated, and full of energy).
3. Odious: Rooted in the word odium (hatred). It describes something that inspires intense disgust, hatred, or aversion. This matches definition Q (Extremely unpleasant; repulsive).
4. Penchant: Borrowed from French, this refers to a strong inclination, taste, or fondness for something. This matches definition S (A strong or habitual liking for something).
Combining these correct pairs gives the sequence: 1-P, 2-R, 3-Q, 4-S. This matches option (A).
Step 3: Final Answer:
The correct combination is 1-P, 2-R, 3-Q, 4-S, which corresponds to option (A).
