The term 'experts in the field' can refer to two different job descriptions: umpires and farmers. Umpires are experts in the field of sports, as they are responsible for making sure that the rules of the game are followed and that the game is fair. Farmers are experts in the field of agriculture, as they are responsible for growing crops and raising livestock. Both umpires and farmers are essential to their respective fields, and both require a great deal of knowledge and skill.
