I want to know the answer to the following question:
How many senior officers were expelled fro the army in 1975?
All the background I'm provided with is that "In January 1977, two dissenting students and a number of army officers were publicly hanged; Amnesty International condemned it as the first time in Gaddafist Libya that dissenters had been executed for purely political crimes.". Is that enough to answer the question?
Answer: no
