    4.  In programming, what is a variable?

                               (i)  A constant value

                               (ii)  A special storage box for information

                              (iii)  A part of the micro:bit

                              (iv)  A type of LED

                          5.  What sensor does the micro:bit use to detect motion?

                               (i)  Light sensor                            (ii)  Temperature sensor

                              (iii)  Accelerometer                          (iv)  Sound sensor

                      B. Fill in the blanks.

                          1.   The micro:bit has a                        grid, containing 25 LEDs.

                          2.  A                     is used in programming to store information that can change
                               during program execution.

                          3.  The Microsoft MakeCode platform allows                                  programming for
                               the micro:bit.

                          4.   The micro:bit’s                       measures motion and direction.

                          5.  The LED display on the micro:bit can be used both as an output device and as
                               a                   .

                      C. State whether the following statements are true (T) or false (F).

                          1.  The micro:bit can only be programmed using text-based coding.

                          2.  The  micro:bit was  developed  to  inspire  children  to  become
                               future digital innovators.

                          3.  Pressing button, A on the micro:bit can increase the count in a
                               simple counter program.

                          4.   The micro:bit does not have any sensors to detect sound.

                          5.  The  accelerometer  in  the  micro:bit  can  detect  motion  in  three
                               axes: X, Y, and Z.
