Consider the following premises. Joseph is rich or William is not taking a plane. If Karen plays squash, then James is curious. If Joseph were rich, then Mary is drinking water. James is curious if and only if William is taking a plane. Can we infer the following from them? The fact that Karen plays squash does not imply that Mary is drinking water.
 From the fact that James is curious if and only if William is taking a plane we can infer that if James were curious, then William is taking a plane. From the fact that Joseph is rich or William is not taking a plane we can infer that if William takes a plane, then Joseph is rich. From the fact that if James were curious, then William is taking a plane, and that if William takes a plane, then Joseph is rich we can infer that if James were curious, then Joseph is rich. From the fact that if James were curious, then Joseph is rich, and that if Joseph were rich, then Mary is drinking water we can infer that if James were curious, then Mary is drinking water. Finally, from the fact that if Karen plays squash, then James is curious, and that if James were curious, then Mary is drinking water we can infer that if Karen plays squash, then Mary is drinking water, which contradicts that The fact that Karen plays squash does not imply that Mary is drinking water. Therefore, the answer is no.
