Consider the following premises. Michael is an astronaut or Robert is playing squash. Linda is playing tennis or Robert is not a doctor. For all y_3, if y_3 plays squash, then y_3 is a doctor. If Michael were an astronaut, then Robert is a doctor. Can we infer the following from them? If we can, name the inference rule being used: Jennifer is reading a book.
We cannot infer that from the premises. Therefore the answer is no.
