Which floor am I on?! Blog This is a picture I took in an elevator in Hong Kong. If you look carefully, you'll see that the numbers 4, 13, 14, and 24 are missing. This is because Hong Kong was once a British colony, so the culture of Hong Kong reflects both Chinese and British superstitions: 4 is considered an unlucky number in China, while 13 is in the U.K. It is interesting to learn about the differences in culture and customs between countries, and knowing the history of a place helps us understand local customs. 3 M 110 10 18 25 9 17 23 2 8 16 22 1 7 15 21 G 6 12 20 LG 5 11 19 Elevator buttons in a Hong Kong building Task 1 Analyze the passage.

4 We created two versions of the menu. Half of the subjects saw a menu that had the word "classic" highlighting the health boost option, whereas the other half saw the health boost highlighted by the word "new." Then our subjects made their choices. 6 As predicted, when the subjects were in the tidy room, they chose the health boost more often almost twice as often - when it had the "classic" label: that is, when it was associated with convention. Also as predicted, when the subjects were in the messy room, they chose the health boost more often more than twice as often when it was said to - be "new"; that is, when it was associated with novelty. Thus, people greatly preferred convention in the tidy room and novelty in the messy room. O difference.
