Answer:Claim (Main idea)
How do I go about supporting it? (ground)
What makes me think that the support is appropriate? (warrant)
What additional support do I have to validate further my claim? (backing)
Example:Claim (main idea): “The Philadelphia Phillies will not be able to repeat as National League baseball champions this season.” P. 201
Ground (support): “The Philadelphia Phillies are not likely to repeat as National League baseball champs because they have released or traded four veteran players who provided needed leadership down the home stretch last season. Furthermore, their young players who played unevenly last year have not proven themselves over the long haul. Finally, some of the older remaining veteran stars on the team had lackluster seasons and show signs of decline.” P. 201-202.
Warrant (inferences): “A baseball team needs to have proven players providing experienced leadership in order t win the pennant in the highly competitive, evenly matched National League.” P. 202.
Backing (justifications): “…we might back the warrant that a National League team needs proven players to win the pennant by referring to the official records of major league baseball and to sabermetrics, the mathematical and statistical analysis of baseball records.” P. 202.
