Navision Questions

Hi,
I have a confusion in some questions. The questions are:
1.What is the value of TheAnswer after executing the following code?
I := 1;
WHILE I < 19 DIV 2 DO
I := I + 3;
CASE TRUE OF
I <= 8: TheAnswer := 'A';
I = 9: TheAnswer := 'B';
I > 9: TheAnswer := 'C';
ELSE TheAnswer := 'D';
END;
A#'A'
B#'B'
C#'C'
D#'D'
2. Select the item that represents an advantage of C/FRONT over C/ODBC for integrating with Navision data stored on the Navision Server.
A#C/ODBC uses a client session. C/FRONT does not.
B#C/FRONT can calculate FlowField values. C/ODBC cannot.
C#C/FRONT instructions are easier to write than C/ODBC instructions.
D#C/FRONT is faster than C/ODBC.
