I want to know the answer to the following question:
How many Pillar industries were there from the 1960s to the 1980s?
All the background I'm provided with is that "From 1960s to 1980s there were Five Pillar Industries, namely, electronics, cars, petrochemical, iron and steel, and power, each with big state-owned firms.". Is that enough to answer the question?
Answer: yes
