Choose the sentence that correctly positions an adverbial clause at the beginning of a sentence:
Answer and explanation
Correct answer: A. Although the results contradicted the hypothesis, the team published the data.
- Step 1: When an introductory dependent adverbial clause (starting with although, because, since, if, while) precedes the independent clause, it must be followed by a comma.
- Step 2: A subordinating conjunction ('Although') should not be paired with a coordinating conjunction ('but') in the main clause.
- Step 3: Option 1 correctly includes the comma and avoids redundant conjunctions.
Answer
Although the experimental results contradicted the original hypothesis, the researchers published the data transparently.
Why not the others: Sentence 2 lacks the obligatory comma separating the introductory dependent clause; Sentence 3 improperly combines 'Although' with 'but'; Sentence 4 awkwardly splits the subject from its verb with an unpunctuated clause.
