Which of the following is a complex sentence?

  • A. When skywriting, a pilot flies a small aircraft in specific, particular formations, creating large letters visible from the ground.
  • B. The public defense attorney was able to maintain her optimism despite her dearth of courtroom wins, her lack of free time, and her growing list of clients.
  • C. Because the distance between stars in the galaxy is far greater than the distance between planets, interstellar travel is expected to be an even bigger challenge than interplanetary exploration.
  • D. Invented in France in the early nineteenth century, the stethoscope underwent a number of reiterations before the emergence of the modern form of the instrument in the 1850s.
Correct Answer: C

Rationale: A complex sentence has one independent clause and at least one dependent clause connected by a subordinating conjunction or a relative pronoun. In choice C, the sentence 'Because the distance between stars in the galaxy is far greater than the distance between planets' is a dependent clause introduced by the subordinating conjunction 'Because,' while the rest of the sentence 'interstellar travel is expected to be an even bigger challenge than interplanetary exploration' forms the independent clause. This combination of an independent clause and a dependent clause makes choice C a complex sentence. Choices A, B, and D do not contain both an independent and dependent clause connected in the way that choice C does, thus they do not qualify as complex sentences.
