Question

consider this paragraph and select the sentence that best uses a subordinating conjunction: the annual science fair approached quickly. students from all grades prepared their projects with great enthusiasm. some worked on chemistry experiments, while others focused on physics demonstrations. the gymnasium buzzed with activity during setup. identify the sentence with the most effective use of a subordinating conjunction: a. while the storm raged outside, we stayed warm by the fireplace. b. the meeting started when everyone arrived. c. i ate dinner and i went to bed. d. the movie was long but interesting.

Explanation:

A subordinating conjunction connects a dependent clause to an independent clause, showing a relationship such as time, cause - and - effect, or contrast. In option a, "while" is a subordinating conjunction that shows a contrast between the storm raging outside (dependent clause) and staying warm by the fireplace (independent clause). Option b uses "when" which is also a subordinating conjunction for time, but the contrast in a is more vivid. Option c uses "and" which is a coordinating conjunction. Option d uses "but" which is a coordinating conjunction.

Answer:

a. While the storm raged outside, we stayed warm by the fireplace.
