Consider the following premises. For all x_8, if x_8 takes a plane, then x_8 is a carpenter. For all x_8, if x_8 were a carpenter, then x_8 is poor. For all x_8, if x_8 were poor, then x_8 is curious. There is at least one x_8 for which if x_8 were a carpenter, then x_8 is taking a plane. Can we infer the following from them? If we can, name the inference rule being used: For all x_8, the fact that x_8 takes a plane does not imply that x_8 is curious.
That contradicts the premises. Therefore the answer is no.
