Identify the syntactic flaw in the sentence: 'The architect drew the blueprints, however, the contractor failed to follow the specifications.'

Answer and explanation

Correct answer: C. run-on sentence with conjunctive adverb

  1. Step 1: The conjunctive adverb 'however' cannot join two independent clauses with only commas. It requires a semicolon before and a comma after ('; however, '), or a period creating two separate sentences, to avoid a run-on/comma splice. Answer: run-on sentence with conjunctive adverb. Why not the others: "dangling participial modifier" occurs when an introductory verbal modifier lacks a logical grammatical subject; "subject-verb number mismatch" occurs when a singular subject is incorrectly paired with a plural verb; "incomplete comparative phrase" omits essential words in a comparison, resulting in ambiguity or illogic.
