You have survived the zombie apocalypse and have been appointed to a research group called the Brain Trust to help rebuild the world. The group's first mission is to provide the president with a list of research topics that can help save the country, such as finding new energy sources, protecting against zombies and other threats, and ensuring food and shelter. Members are instructed to choose a topic, explain how it can help, and write three research questions on the topic to provide focus for their research.
