I want to know the answer to the following question:
What do these efforts include
All the background I'm provided with is that "A key aspect of the Gates Foundation's U.S. efforts involves an overhaul of the country's education policies at both the K-12 and college levels, including support for teacher evaluations and charter schools and opposition to seniority-based layoffs and other aspects of the education system that are typically backed by teachers' unions.". Is that enough to answer the question?
