I want to know the answer to the following question:
How many of the textbooks between 1983 and 1992 discussed race?
All the background I'm provided with is that "Morning (2008) looked at high school biology textbooks during the 1952-2002 period and initially found a similar pattern with only 35% directly discussing race in the 1983–92 period from initially 92% doing so.". Is that enough to answer the question?
Answer: yes
