Entailments vs. Presuppositions

For the following pairs of sentences, decide whether the second sentence is an entailment of the first, or is a presupposition, or whether there is no relation. Support your answer by performing test(s), evaluating the results, and describing the conclusions.

Some strategies you will want to use:

• p → q iff p & ¬q is a contradiction. Try to construct a sentence of this form. and decide whether it is contradictory.

• To show that p does not entail q, find a situation where p is true and q is false

• To show that p presupposes q, construct a sentence with a non-veridical environment, and put the sentence of p in the environment, and then test whether or not q is still entailed
