Input: Consider Input: Passage: Muscles cannot contract on their own. They need a stimulus from a nerve cell to "tell" them to contract. Let's say you decide to raise your hand in class. Your brain sends electrical messages to nerve cells, called motor neurons, in your arm and shoulder. The motor neurons, in turn, stimulate muscle fibers in your arm and shoulder to contract, causing your arm to rise. Involuntary contractions of cardiac and smooth muscles are also controlled by nerves. Answer: stimulus

Output: What do muscles need to contract?

Input: Consider Input: Passage: A population is a group of individuals of the same species that live in the same area. The population is the unit of natural selection, adaptation, and microevolution.

Output: What term refers to a group of individuals of the same species that live in the same area and is the unit of natural selection, adaptation, and microevolution?
