T
F
NIL
-20 E. None of the above
Answer is Right!
Answer is Wrong!
The correct answer is A. T.
The function (minusp (-20 4 8 8 1)) returns T because the result of the expression (-20 4 8 8 1) is negative.
The function minusp takes two arguments and returns T if the first argument is less than the second argument, and F otherwise. In this case, the first argument is -20 and the second argument is 1. Since -20 is less than 1, the function returns T.
The other options are incorrect for the following reasons:
- Option B: F is returned if the first argument is not less than the second argument. In this case, the first argument is -20 and the second argument is 1. Since -20 is less than 1, the function does not return F.
- Option C: NIL is returned if the first argument is equal to the second argument. In this case, the first argument is -20 and the second argument is 1. Since -20 is not equal to 1, the function does not return NIL.
- Option D: -20 is the first argument to the function. The function does not return the first argument.
- Option E: None of the above is the correct answer.
