Answer:
B. the door-in-the-face strategy
Step-by-step explanation:
The door-in-the-face strategy is a largely used method in social psychology, marketing and sales. It starts with the seller/advertiser/persuader having a big request for the other person, knowing it will probably be turned down. Afterward, the seller/advertiser/persuader proposes a smaller request.
Many studies and researches have shown that people would more often say yes to the smaller request when it is made following the large request, rather than the small request being proposed alone.
In this example, the advertising committee is hoping that people would surely accept the smaller lawn sign after they initially propose the big sign, due to this strategy.
