But Australian researchers have found a way to make something like this possible! A team at RMIT University in Melbourne, Australia, found a way to put special nanostructures into clothing, which can then clean the clothes. When sunlight hits the nanostructures, they break down the dirt and stains that don't belong on your clothes. The nanostructures don't break down the actual clothing because cotton and the other clothing materials are too strong to be broken down. According to CNN, the researchers cover the clothing in a solution made of silver and copper nanostructures. All it takes is 40 minutes of sunlight and your clothes will look as good as new. So if you spill on yourself during lunch, you can step outside for a walk, and it will be clean by the time you go inside. It not only makes your life easier, but it can also be good for the environment. According to the US Department of Energy, the average load of laundry uses about 25 gallons (about 94 liters) of water. Water is a very important resource, so using less of it to wash clothes is better for the environment. But one of the scientists at RMIT University knows more needs to be done. "There's more work to do before we can start throwing out our washing machines," said Dr Rajesh Ramanathan, "but this is a strong foundation ." So what's the next step? Ramanathan wants to either start selling the solution by itself or convincing clothing makers to treat the clothing with the solution while clothes are being made. Question: What can we learn from the passage? Options: A: Silver and copper sell well. B: The solution is not put into practice. C: Clothing makes certainly like the solution. D: We don't need washing machines any more.

But designer Mikhail Belyaev doesn't think that forgetting to check the weather report before going out should cause you to get wet in the rain. That's why he created the Lampbrella--a lamp post with its own "umbrella". The designer says he came up with the idea after watching people get wet on streets in Russia. "Once, I was driving on a central Saint Petersburg street and saw people trying to hide from the rain under the street lamps. I thought it would be a good idea to have a Lampbrella built into a street lamp." he said. The Lampbrella is a street lamp fitted with an umbrella canopy . It has an inside electric motor which can open or close the umbrella freely. The Lampbrella will offer people cover whenever it starts raining. After three minutes of not being used the canopy is closed. According to the designer, the Lampbrella would move at a very low speed in order not to cause harm to people. What's more, it would be grounded to protect from a possible lightning hit. Each Lampbrella would offer enough cover for several people. Being 2 meters off the ground, it would only be a danger for the tallest man. While there are no plans to take the Lampbrella into production , Belyaev says he recently introduced his creation to one Moscow company, and insists his creation could be on any street where a lot of people walk but there are no canopies to provide cover. Question: According to the passage, for what purpose did Belyaev create the Lampbrella? Options: A: To know when there'll be a heavy rain. B: To check the weather report. C: To protect people from the rain. D: To remind people to take an umbrella.
