4. For each of the following sentences, write 'T' or 'F' next to it, according to whether it is true or false in the world shown below. (Please do not use the program Tarski's World to generate your answers - figure it out yourself, perhaps using a circuit diagram. You may, however, use the program to check your answers.) 1. Dodec(c) v Cube(c) 2. Tet(f) v Small(f) 3. Cube(c) Cube(e) 4. b = e 5. cf (N.B. This is a lazy way of writing c=f, i.e. c isn't identical to f.) 6. 7. 8. 9. ר ר (Dodec(c) v Dodec(f)) (Cube(a) A Cube(e)) Small(a) (SameSize(e, c) v 10. Medium(c) v Larger(f, c)) SameRow(b, e) V ( Dodec(f) - SameSize(a, b)) b 0 Ф 5. Draw a world in which all the sentences from Qu. 4 are true. (A couple of modifications to the world shown above will do it.) г
