In the following question, one part of the sentence may have an error. Find out which part of the sentence has an error and select the appropriate option; if the sentence is free from error, select "No Error". I remember him as someone who was a lot nicer than circumstances warranted.

Introduction / Context:
This error spotting question asks you to judge whether any segment of the sentence is grammatically or idiomatically incorrect. The sentence expresses a comparison between how nice a person was and how nice the circumstances would normally make someone. It is written in standard narrative style.

Given Data / Assumptions:

• Full sentence: I remember him as (A) someone who was a lot nicer (B) than circumstances warranted. (C) No Error (D)
• Part A: "I remember him as"
• Part B: "someone who was a lot nicer"
• Part C: "than circumstances warranted."
• Part D: "No Error"

Concept / Approach:
The structure "remember someone as" is correct when you recall a person in a certain role or character. The phrase "a lot nicer" is an informal but acceptable intensifier before the comparative adjective "nicer." The comparative clause "than circumstances warranted" is also idiomatic, meaning that the person was kinder than the situation required.

Step-by-Step Solution:
Step 1: Check part A: "I remember him as." This is a correct way to introduce the description of how you recall someone. Step 2: Check part B: "someone who was a lot nicer." The relative clause "who was a lot nicer" correctly modifies "someone" and uses the comparative "nicer" correctly. Step 3: Check part C: "than circumstances warranted." This phrase correctly completes the comparison and uses the verb "warranted" in the past tense, matching the past "was." Step 4: Since parts A, B, and C are all correct, there is no error in the sentence. Step 5: Therefore the appropriate choice is "No Error."

Verification / Alternative check:
Try to substitute possible corrections. For example, "I remember him to be someone who was a lot nicer" is less natural than "remember him as someone who was a lot nicer." Changing "warranted" to "warrants" would disturb tense consistency. The original version already reads smoothly and naturally, which supports the conclusion that it is error free.

Why Other Options Are Wrong:

• A: Contains no grammatical or idiomatic error; "remember him as" is standard.
• B: Uses "a lot nicer" correctly as an informal degree marker before a comparative.
• C: The clause "than circumstances warranted" is well formed and properly completes the comparison.

Common Pitfalls:
Students sometimes suspect an error simply because a phrase sounds slightly informal, such as "a lot nicer." However, modern competitive exams accept many natural spoken English forms as long as they are grammatically correct. The challenge is to distinguish between informal but acceptable usage and genuine errors in structure or agreement.

Final Answer:
The sentence is grammatically correct, so the right choice is D (No Error).
