Meaning relations between propositions

identify whether (a) entails (b), (a) presupposes (b), (a) implicates (b), or
none or more than one of the above. Then, identify whether (b) entails (a), (b) presupposes (a), (b) implicates
(a), or none or more than one of the above. Finally, indicate whether (a) and (b) are contradictory, contrary,
paraphrases, or independent. Briefly explain your answers (about 3 sentences). For each pair of sentences,

for both sentences. Additionally, note that some of the sentences may be ambiguous in ways that affect your
answers.
