Which of the following were reasons why the Soviet Union was in such dire economic straits during the later 1980s?
drastically higher cost of oil imports
the protracted Afghanistan War
a series of failed economic programs
its Capitalistic economy was failing fast
increasing amounts of defense spending
The best option from the list would be "a series of failed economic programs," since it was operating under a "command economy"--meaning that government had to "guess" supply and demand.
