Question

question 20
you can perform a ___ by making comparisons using either the lowest or highest value in a range of values.
o logic check
trivial expression
nested if
range check
question 21
in a truth table, the expression ___ is false.
o false or true
true or false
true or true
false or false

Explanation:

Question 20

A range check specifically involves comparing values within a range, using the lowest or highest value as reference points. A logic check is more about evaluating logical conditions in general. A trivial expression is a simple, often unimportant expression. A nested if is a conditional structure within another conditional structure. So, the term that fits the description is "range check".

Question 21

In boolean logic (used in truth tables), the OR operation has the following rules: \(False\ OR\ False = False\), \(False\ OR\ True=True\), \(True\ OR\ False = True\), \(True\ OR\ True=True\). So the expression that is false is "false OR false".

Answer:

Question 20: range check
Question 21: false OR false
