Answer 1

The above problem can be solved as follows-

Dear student, your question has multiple parts to the question and as HOMEWORKLIB's Policy, which states that -

Multiple Sub-Part Qs - Answer the first 4 sub-parts, unless the student has asked for specific subpart(s) to be answered, subject to a maximum of 4 sub-parts.

So I can only solved first 4 subparts Q 1,2,3 and 4 as no specific part has been mentioned.

QUESTION 1

Answer - Option D - Then

Explanation -  First 3 options, not, or, and are logical operators in Visual Basic and they are used in logical statements that evaluate to true/false.

But the word then is not used as logical operator but as in if-then-else statements. So it is correct answer as its not a logical operator.

QUESTION 2-

Answer - Option D - (2<n) or (n<5)

Explanantion - This is the correct options as it follows the syntax as it should. Option A is not correct logical sequence and Option B does not brackets around the conditions. And option C is same as Option A so both are incorrect.

In this way Option D is the correct choice.

QUESTION 3

Answer - Option A - short circuit

Explanation - This option A is the correct answer as the situation when and expression is being evaluated and the first expression results in false, due to which the next statement is not evaluated, is known as short circuit.

Pre , compound and first are not the correct words used for this behaviour.

QUESTION 4-

Answer - Option C - "GMC"<="GMC"

Explanation - This is becaue the first statement is false because "Ford" is not less than "Ford". They are same/equal.

The second statement compares "Chevy" with itself with > operator but they are again same/equal

The third statement which return true is that "GMC" may not be less than "GMC" but they are equal. That is why it returns true because although not < but they are =.

And the last is not true because "oldsmobile" is actually > than "Oldsmobile" and not < assuming their ASCII values for comparison.
