Evidence you offer to support a claim is called grounds. This information is usually based on appeals (ethos, pathos, logos). This information is usually based on appeals (ethos, pathos, logos). Example: Example: Reason: (Because) the Earth cannot sustain its population indefinitely, Reason: (Because) the Earth cannot sustain its population indefinitely, Warrant: (And) the viability of our atmosphere is in danger, Warrant: (And) the viability of our atmosphere is in danger, Backing: we should help save furture mankind by finding a new place to live; (pathos) Backing: we should help save furture mankind by finding a new place to live; (pathos) Backing: it is up to the greatest minds in the nation to solve the situation; (ethos) Backing: it is up to the greatest minds in the nation to solve the situation; (ethos) Backing: it only makes sense that we form a new habitat for humanity; (logos) Backing: it only makes sense that we form a new habitat for humanity; (logos) Claim: therefore, NASA should launch a human expedition to Mars Claim: therefore, NASA should launch a human expedition to Mars Grounds: so humanity can have new resources to sustain us. (logos) Grounds: so humanity can have new resources to sustain us. (logos) Grounds: so we can spread the miracle of humanity to the universe. (pathos) Grounds: so we can spread the miracle of humanity to the universe. (pathos)
