I want to know the answer to the following question:
How many commercial films were produced yearly on average by the end of the 1960s in Iran?
All the background I'm provided with is that "With the screening of the films Kaiser and The Cow, directed by Masoud Kimiai and Dariush Mehrjui respectively in 1969, alternative films established their status in the film industry.". Is that enough to answer the question?
Answer: no
