Q7.3c — Complex Symbolizations

Each symbolization exercise has an infinite number of correct answers. (Think about why this is so!) Now, for the sentences which follow, give 3 different correct symbolizations for each. These are started for you...replace the question marks (or come up with your own).

universe of discourse: People
Ax: x is an astronaut
Fx: x is female
Sxy: x is the spouse of y
Pxy: x is the parent of y

  1. Some female astronaut has a spouse who is also an astronaut.

    (give three different but equivalent symbolizations here)




  2. All astronauts have a parent who is not an astronaut.
