Exercise 1.13.5: Determine and prove whether an argument in English is valid or invalid. Prove whether each argument is valid or invalid. First find the form of the argument by defining predicates and expressing the hypotheses and the conclusion using the predicates. If the argument is valid, then use the rules of inference to prove that the form is valid. If the argument is invalid, give values for the predicates you defined for a small domain that demonstrate the argument...

Validity, Soundness, Strength, Cogency - Practice Arguments 2 Determine whether each of the following arguments is a deductive argument or an inductive argument. If the argument is a deductive argument, then evaluate the argument for its validity and soundness. If the argument is an inductive argument, then evaluate the argument for its strength and cogency. Use the selection lists beneath each argument to indicate your answers. Argument A An aardvark is (deductive/inductive) , (valid/invalid/strong/weak) , and (sound/unsound/cogent/uncogent) . Argument B...
