A6. A researcher is pondering what survey mode to use for a client who markets a security system for offices. The system comprises sensors that are pressed onto all of the windows and magnetic strips that are glued to each door. Once plugged into an electric socket and activated with a switch box, the system emits a loud alarm and simulates the sound of police car when an intruder trips one of the sensors. The client wants to know how many offices in Hong Kong are aware of the system, what they think of it, and how likely they are to buy it in the coming year. Please assess the suitability of the following survey modes:

(i) In-home interview (1 mark) (ii) Mall intercepts (1 mark) (iii) Drop off survey (1 mark) (iv) CATI (1 mark)
