I want to know the answer to the following question:
After 1992, what did the percentage of textbooks discussing race increase to?
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: no
