A brain trust is a group of smart people who work together to solve problems or come up with new ideas. Think of it like a team of superheroes, each with their own special powers, who come together to save the day. In a brain trust, each person has their own unique skills and knowledge that they bring to the table. When they work together, they can come up with amazing solutions to even the trickiest of problems. Sometimes, brain trusts are used in business, government, or other organizations to help them make important decisions. It's like having a team of geniuses all working together to help make the world a better place.
