To avoid confusion, I'll try to avoid letters where it's hard to tell the difference between upper and lowercase, and you should do the same (e.g., don't use C or O or X ). Also, for this assignment, we will treat Y as a vowel. Use the following interpretations for the predicate symbols. V(x): " x is a vowel." L(x): " x is lowercase." F(x) : " x is from the first half of the alphabet." When asked to translate a formula into a "natural-sounding" English sentence, remember that you can't use any variables in the sentence (so nothing like "For every letter x... ), and your sentence must be unambiguous (so nothing like "Every vowel is not..."). M1:M2:M3:M4:M5:M6:M7:M8:eeBEeeeEAAdAaAaAijjjjIiBETTTTTuT (a) Which of the above models (M1M8) satisfy the formula x(V(x)L(x)) ? Hint: This is the same as asking for models that do not satisfy x(V(x)L(x)). (b) Translate x(V(x)L(x)) into a natural-sounding English sentence. (c) Which of the above models (M1M8) satisfy the formula x(V(x)L(x)) ? Hint: This is not the same as the formula in the previous question. (d) Translate x(V(x)L(x)) into a natural-sounding English sentence. (e) Which of the above models (M1M8) satisfy the formula x(V(x)L(x)) ? (f) Translate x(V(x)L(x)) into a natural-sounding English sentence. (g) Which of the above models (M1M8) satisfy the formula x(V(x)L(x)) ? (h) Translate x(V(x)L(x)) into a natural-sounding English sentence
