I want to know the answer to the following question:
WHat program compliment reinvent the toilet
All the background I'm provided with is that "In 2011, the foundation launched a program called "Reinvent the Toilet Challenge" with the aim to promote the development of innovations in toilet design to benefit the 2.5 billion people that do not have access to safe and effective sanitation.". Is that enough to answer the question?
Answer: no
