Explanation / Answer

1. The Select Case statement must include a Case Else clause. False. The Case Else is optional actually.

2. A variable of type Long that equals 5 consumes less memory than a variable of type Integer that equals 5,000. True. A Long data type is formally allocated 8 bytes, but is not the same always.

3. A For-Next loop must specify a Step value. False. Step is an option here.

4. A Do loop may evaluate a While condition before or after the loop body. True. It depends on while or until.

5. In the Next statement of a For-Next loop, the name of the loop-counter variable name may optionally be provided.  
    For i As Integer = 0 to 10
        ' Statements here
    Next i
If the variable name is omitted from the Next statement, it defaults to 1. True.
