For the argument: represent the argument symbolically; determine whether the argument is valid or invalid (justify your conclusion by a proof of validity or Euler diagrams, as needed); and examine the argument for soundness (give a short explanation or justification for your conclusions). Argument: All thieves are liars. Some presidential candidates are not liars. Therefore, some presidential candidates are not thieves.

2. Let P(x) be "x is a student in this class," Q(x) be “x knows how to write programs in Python," and R(x) be “x can get a good job," where the domain of x consists of all people. Write the following argument in argument form and use the rules of inference to show that the argument is valid. Tom is a student in this class. Tom knows how to write programs in Python. Everyone who knows how to write programs in Python can get a good job. Therefore, some student in this class can get a good job.
