English Grammar — Spot the error (choose the incorrect part; select 'No error' if the sentence is correct). Sentence parts: A) Even though it was B) raining bad I C) went out to D) get some medicines. E) No error

Introduction / Context:
This item checks adverb vs. adjective usage after weather-related verbs and punctuation/pausing within a clause introduced by a concessive marker “Even though.”

Given Data / Assumptions:

• Segment B uses “raining bad I.”
• “Raining” is a verb-like usage; manner adverb should follow.
• A comma is normally expected after the subordinate clause.

Concept / Approach:
“Rain” when used progressively as a verb takes an adverb of manner like “heavily” or “badly,” not the adjective “bad.” Also, after a lengthy dependent clause beginning with “Even though it was …,” a comma is typically placed before the main clause.

Step-by-Step Solution:

Verification / Alternative check:
Try “Even though it was raining badly, I went out …” The meaning and grammar improve, confirming Segment B as erroneous.

Why Other Options Are Wrong:

• A: Correct concessive opener.
• C: Grammatically fine verb phrase.
• D: Acceptable object phrase.
• E: Not applicable because B contains an error.

Common Pitfalls:
Learners often use adjectives where adverbs are needed, especially with weather verbs. Also, missing a comma after an introductory dependent clause is common, but the principal tested error here is the adverb choice in B.

Final Answer:
B) raining bad I
