(9) It’s too bad it can’t be like that on Earth too, we would be so much happier if it was. (10) But in the meantime, at least humans can enjoy such peaceful harmonious conditions on the ISS.


Which sentence correctly uses a subordinating conjunction to combine sentences 5 and 6 into one complex sentence?
A. Since the astronauts on board conduct a variety of experiments in biology, physics, astronomy, materials science, and space science, the ISS also functions as a space laboratory.
B. Either the astronauts onboard conduct a variety of experiments in biology, physics, astronomy, materials science, and space science, or the ISS also functions as a space laboratory.
C. The ISS also functions as a space laboratory, although the astronauts on board conduct a variety of experiments in biology, physics, astronomy, materials science, and space science.
D. The ISS also functions as a space laboratory, yet the astronauts on board conduct a variety of experiments in biology, physics, astronomy, materials science, and space science.

A.

"Since" is a subordinating conjunction that correctly links the dependent clause (Since the astronauts on board conduct a variety of experiments...) to the independent clause (the ISS also functions as a space laboratory) and gives the correct cause-effect meaning. Options B and D use coordinating or correlative conjunctions, and C uses "although," which gives the wrong contrast.
