1 Type-shifting Recall these natural deduction rules for implication elimination and introduction shown: (1) B : A-B a : A (2) [a : Ajl B(a) : B B : B -I,1 Aa. B : A - B For each of the type shifts below, show how the logic of implication derives the more complex type (right side) from the simpler type (left side), using.' 1. at ((a, b), b) Lift (Montague) 10 points 2. (a, b), (b, c) + (a, c) Composition (Geach) 10 points 3. (((a, b), b), c) + (a,c) Argument Lowering (Partee & Rooth) 10 points 2 Type-shifting in action For each of the shifts in $1: 4. provide a natural language example that shows a use of the shift in action; and 15 points 5. explain how the example exemplifies the shift. 15 points Note: For #5, you can choose to explain it in words or to show a proof (or a combination).
