(True/False (√))
17. The edges of the decision tree represent corresponding actions to be performed according
to conditions. (True/False (√))
18. The upper rows of the decision table specify the corresponding actions to be taken when
an evaluation test is satisfied. (True/False (√))
19. A column in a decision table is called an attribute. (True/False (√))
20. Pre – conditions of axiomatic specifications state the requirements on the parameters of
the function before the function can start executing.(True (√)/False (√))
21. Post – conditions of axiomatic specifications state the requirements on the parameters of
the function when the function is completed. (True (√)/False (√))
22. Applications developed using 4 GLs would normally be more efficient and run faster
compared to applications developed using 3 GL. (True/False (√))
