Step 1: Understanding the Concept:
Synonyms are words that convey a similar meaning. To identify the synonym for "zest," one must look at the context of the sentence, which describes "vitality" and "life force." Understanding the tone—which is about the vigor of living—is key to matching the right intensity with the options provided.
Step 2: Analyzing the Context:
The sentence uses "zest" in the context of "zest for life." This phrase is a common idiomatic expression referring to a keen enjoyment or interest in life. Therefore, the synonym must relate to high energy, passion, or excitement.
Step 3: Detailed Reasoning:
• Zenith (A): This noun refers to the highest point or peak. It does not relate to the emotional state of "zest."
• Enthusiasm (B): This noun represents intense and eager enjoyment or interest. It matches the energetic, positive nature of "zest" perfectly.
• Propensity (C): This refers to an inclination or natural tendency. It is a neutral term that lacks the "passion" implied by "zest."
• Satisfaction (D): This is the state of being content. While one might be satisfied, "zest" implies a more active, outward-moving energy than simple satisfaction.
Step 4: Final Answer:
The word similar in meaning to "zest" is enthusiasm.
