The End If statement is required:

  1. in all If...Then statements.

  2. in all Multi-line statements with Else.

  3. in Single Line statements.

  4. Both a and b.

  5. All of the above.


Correct Option: B

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) In all If...Then statements - This option is incorrect. The "End If" statement is not required in all If...Then statements. It is only required in multi-line If...Then statements.

Option B) In all Multi-line statements with Else - This option is correct. In multi-line If...Then statements that include an Else clause, the "End If" statement is required to indicate the end of the If...Then block.

Option C) In Single Line statements - This option is incorrect. In single-line If...Then statements, the "End If" statement is not required.

Option D) Both a and b - This option is incorrect. Option A is incorrect, as mentioned earlier.

Option E) All of the above - This option is incorrect. Option C is incorrect, as mentioned earlier.

Therefore, the correct answer is B) In all Multi-line statements with Else. This option is correct because the "End If" statement is required in multi-line If...Then statements that include an Else clause to indicate the end of the If...Then block.

Which selection process is an example of multiple branches from a single expression?

  1. If...Then

  2. Select Case

  3. Do...Loop

  4. For...Next

  5. All of the above.


Correct Option: B

How many times is the test expression of a Select Case evaluated?

  1. 1

  2. 2

  3. Once for each Case.

  4. It depends on the value of the test expression.


Correct Option: A

Which is not a type of Select Case test construct?

  1. simple value

  2. complex value

  3. relational value with Is

  4. range of values with To

  5. All of the above are types of test constructs.


Correct Option: B

What happens in a Select Case construct when a test value matches the test expression?

  1. The corresponding block of statements is run.

  2. The next Case test value is checked.

  3. The Case Else statement is run.

  4. The Select Case construct is exited.

  5. An error is generated.


Correct Option: A
  1. selects a block of statements to run.

  2. runs the same block of statements repeatedly.

  3. selects a block of statements and runs it repeatedly.

  4. selects a block of statements and runs it a specified number of times.

  5. All of the above.


Correct Option: B

Which is true of a Do...Loop?

  1. The While condition goes after the Do keyword.

  2. The Until condition goes after the Do keyword.

  3. The While condition goes after the Loop keyword.

  4. The Until condition goes after the Loop keyword.

  5. All of the above.


Correct Option: E

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) The While condition goes after the Do keyword. - This option is incorrect. In a Do...Loop, the condition is checked at the end of the loop, so the While condition is placed after the Loop keyword.

Option B) The Until condition goes after the Do keyword. - This option is incorrect. Similar to Option A, the Until condition is also placed after the Loop keyword in a Do...Loop.

Option C) The While condition goes after the Loop keyword. - This option is incorrect. The While condition is placed after the Do keyword, not the Loop keyword.

Option D) The Until condition goes after the Loop keyword. - This option is incorrect. Similar to Option C, the Until condition is also placed after the Do keyword, not the Loop keyword.

Option E) All of the above. - This option is correct. None of the previous options correctly state the placement of the condition in a Do...Loop. Therefore, the correct answer is E.

The correct answer is E. All of the above. This option is correct because none of the previous options accurately describe the correct placement of the condition in a Do...Loop.

  1. Do While Score > 100

  2. Do Until Score > 100

  3. Loop While Score > 100

  4. Loop Until Score > 100

  5. All of the above are valid for this situation.


Correct Option: B
  1. -1

  2. 1

  3. 2

  4. There is no default for the step value.


Correct Option: B

The For...Next Loop is used when:

  1. a choice is made based on a Boolean condition.

  2. a block of statements is executed an unknown number of times.

  3. a block of statements is executed a known number of times.

  4. Both a and b.

  5. All of the above.


Correct Option: C
