Which of these shops sells Kate's dream dress?这些商店里哪一家卖凯特梦寐以求的那条裙子?

A. BeaverYorker

B. Beaver Nova

C. B&B

D. Tom Teaver

 

 

 

 

 

Explanation 解释

The correct answer is: B&B

正确答案是:B&B

To solve this task, one must simultaneously satisfy three requirements. This can be done by discarding coats that do not meet any one of the requirements. After doing this, one can see that the dress on the bottom left sold by B&B is Kate's dream dress.

要完成这项任务,必须同时满足三个条件。这可以通过舍弃不符合其中任何一个条件的外套来实现。做完这些之后,就可以看出左下角 B&B 出售的那件连衣裙正是凯特梦寐以求的那件。

The other answers are incorrect because

其他答案都是错误的,因为

  • The only dress sold by BeaverYorker with stars on the sleeves has long sleeves;贝弗约克出售的唯一一款袖子上有星星图案的连衣裙是长袖的。
  • Beaver Nova does not sell any coats with more than three buttons;比弗·诺瓦不销售任何有超过三个纽扣的大衣。
  • The only dress sold by Tom Teaver with more than three buttons, has long sleeves.汤姆·蒂弗出售的唯一一件有超过三个纽扣的连衣裙是长袖的。
