Take the following as truth: The problem is that Kodak really had little evidence to show that it was being frozen out by the Japanese government . There was the retail-stores law, and Kodak produced evidence of state intervention to restrict imports, but it was evidence from the 1960s and 1970s.
Then the following statement: "The 1960s and 1970s was a more difficult time for Kodak." is true, false, or inconclusive?
Answer: Inconclusive
