What can you infer about the two early space stations, based on the graphic above?
The Soviets' space station was faster.
The Soviets did not accomplish a significantly better space station in 13 years.
The American space program was less developed than the Soviet space program.
Skylab was significantly larger.

        i'm fairly sure that the correct answers are 2 and 3.

        i used both my knowledge of world history and the process of elimination to obtain these answers. option 1 cannot be a possible selection because the mandate of heaven belongs to ancient chinese philosophical belief. option 4 sounds like it would benefit the region than detriment it. however, both 2 and 3 explain a potential reason for what could have contributed to the fall of the roman empire.

      hope this ! if i were you, i'd get a second opinion, because i haven't taken this course for a year. best of luck!
