Short Answer

If the following argument is an instance of one of the "famous" argument forms, name the form and indicate whether the form is valid or invalid; if the argument is NOT an instance of one of the "famous" forms, simply write "unnamed form."
If Theresa buys the first-edition Greg Baer novel, then she will have Mr. Baer autograph it on Monday. If Theresa buys the first-edition Orson Scott Card novel, then she will have Mr. Card autograph it on Tuesday. Since she's either going to buy the first-edition Greg Baer novel or she's going to buy the first-edition Orson Scott Card novel, she'll either have Mr. Baer autograph his novel on Monday or she'll have Mr. Card autograph his novel on Tuesday.
