Bill Gates, the founder of Microsoft and one of the richest people in the world, is now making efforts to reinvent the toilet. Gates has donated a big part of his wealth to charity. Now his charitable organization, the Bill & Melinda Gates Foundation, is looking for future toilets that can improve the living conditions of millions of people. The flush toilet we use today was invented in 1775. While it works well in getting rid of our waste, it also uses a lot of water and needs a costly sewage system . Besides, it's not necessarily practical for the developing world. In some developing countries, lack of toilets leads to poor hygiene ,and _ could kill people. According to the World Health Organization, 1.5 million children under the age of five die each year because of hygiene problems. Last year, the Gates Foundation gave money to eight universities around the world and asked them to start inventing the toilet of tomorrow: a toilet that uses little or no water is cheap and easy to fix, and is safe and hygienic. At the " Reinvent the Toilet Fair " competition recently held in Seattle, twenty-eight designs were displayed. The winners, from the California Institute of Technology , were awarded a $ 100,000 prize by the Gates Foundation. "We couldn't be happier with the response that we've gotten," Bill Gates said at the event. Many of the new designs would not only greatly improve hygiene in the developing world, but also help change the dependence on traditional flush toilets in developed nations, he said. What are disadvantages of the flush toilet we use today? A) Wasting a lot of water and energy. B) Washing a lot of water and needing a costly sewage system. C) Spending too much time and energy. D) Improving hygiene and environment.

(Question)
There are many unusual hotels around the world. In Greenland , there is a hotel made of ice, open between December and April every year. In Turkey , there is a cave hotel with a television, furniture, and a bathroom in each room. And in Bolivia , there is a hotel named the Salt Palace Hotel. Thousands of years ago, the area around the Salt Palace Hotel was a large lake. But today, the area has only two small lakes and two salt deserts . The larger of the two deserts is called Uyuni salt desert. During the day, the desert is bright white because of the salt. There are no roads across the Uyuni desert, so local people must show guests the way to the hotel. In the early 1990s, a man named Juan Quesada built the hotel. He cut big blocks of salt from the desert and used the blocks to build it. Everything in the hotel is made of salt: the walls, the roof , the tables, the chairs, the beds, and the hotel's bar. The sun makes the walls and roof warm during the day. At night the desert is very cold, but the rooms are warm. The hotel has twelve rooms. A single room costs$40 a night, and a double room costs$60. A sign on the hotel's wall tells guests, " Please don't lick the walls." [:Zxxk.Com] Which sentence about the area around the Salt Palace Hotel is NOT true? A) It was a lake many years ago. B) It is white during the day. C) There are several roads to the hotel. D) There are only two small lakes now.
