Consider the following premises. Linda is fast. For all x_14, x_14 will not take a plane. Elisabeth is taking a plane if and only if Jennifer is poor. Can we infer the following from them? Jennifer is not poor and Linda is fast.
 From the fact that for all x_14, x_14 will not take a plane we can infer that Elisabeth is not taking a plane. From the fact that Elisabeth is taking a plane if and only if Jennifer is poor, and that Elisabeth is not taking a plane we can infer that Jennifer is not poor. Finally, from the fact that Jennifer is not poor, and that Linda is fast we can infer that Jennifer is not poor and Linda is fast. Therefore, the answer is yes.
