Is the following disjunctive argument valid? Explain your answer making reference to the disjuncts as either inclusive or exclusive. 1. Either Amy will have her contract renewed or she will have to look for another job. She is looking for a new job, so her contract must not have been renewed. 2. The planet's rings are formed of either rock or ice, and cannot be formed of both substances. We have no way of testing for ice using technology, but we can test for rock. Using this test, we have discovered that the rings do consist of rock, so they must not be made up of ice.
