4. What does the robot do when it detects a red block (in the demo behavior)?

A) RGB turns red, buzzer beeps once, robot rocks forward/back B) RGB turns blue, buzzer beeps twice, robot rocks left/right C) The robot stops and powers off D) The robot starts following a line

5. What does the robot do when it detects a blue block (in the demo behavior)?

A) RGB turns red, buzzer beeps once, robot rocks forward/back B) RGB turns blue, buzzer beeps twice, robot rocks left/right C) The robot powers off immediately D) The robot starts WiFi streaming

6. If neither red nor blue is detected, what color does the RGB LED show (in the demo)?

A) White B) Green C) Purple D) Off

7. Why does Hiwonder recommend removing the Bluetooth module before uploading programs?
