Article: Ahead of so-called Singles' Day on the 11th of this month,2013, online sales have already begun peaking. The leading e-business platform, tmall.com, has promoted its fifty-percent-off discount to attract consumers. They are also trying to attract buyers through social media. Vice President of tmall.com Wang Yulei says more than 20 thousand online stores have joined the Double 11 Day sales. But this number has doubled. The final number of how many products going to be on sale has not been known yet. But so far, many more products planned to be put on shelves with discounts. During last year's Singles' Day, tmall.com, together with taobao.com, reached a record of 19.1 billion yuan in sales, which considered a milestone in the e-business history of China. Singles' Day was first started by Chinese college students in the 1990s as the opposite of Valentine's Day, a celebration for people without romantic partners. The timing was based on the date: Nov. 11--or double 11--for singles. Single young people would treat each other to dinner or give gifts to show love to someone and end their single status. But now, the Singles' Day has been promoted as a kind of grand craze just for the shopping season, thanks to thousands of discounted products being promoted online. Taobao.com was the first big e-retail platform which used the double 11 idea to promote sales. Taobao.com reached one million yuan worth of sales on that day in 2009, when they first promoted the Singles' Day idea. In 2010, the sales increased to 936 million yuan. The figure climbed up to 5.3 billion yuan in 2011, putting huge demand on shipping services. The figure doubled in 2012. E-commerce is considered to be replacing the traditional retailing industry, but the reality is both sides are learning from each other. Question: What can we infer from the passage? Answer:
A:
output: Double 11 Day was created to get the single status over for young people.

- Scientists searching for treasure with special equipment.
- New methods of doing geological study.
- Gold could be found in trees and plants.
- A new method of searching for minerals. Now, answer this question: Read the following article and answer the question. Article: Flying over a desert in an airplane, two scientists looked down with trained eyes at trees and bushes. After an hour's flight one of the scientists wrote in his notebook, "Look here for probable metal." Walking across hilly ground, four scientists reported, "This ground should be searched for metals." From an airplane over a hilly wasteland a scientist sent back by radio one word "Uranium". None of the scientists had X-ray eyes: they had no magic powers for looking down below the earth's surface. They were merely putting to use one of the newest methods of locating minerals in the ground -- using trees and plants as signs that certain minerals may lie under the ground on which the trees and plants are growing. This newest method of searching for minerals is based on the fact that minerals deep in the earth may affect the kind of bushes and trees that grow on the surface. At Watson Bar Creek, a mineral search group gathered bags of tree seeds. Boxes were filled with small branches from the trees. Roots were dug and put into boxes. Each bag and box was carefully marked. In a scientific laboratory the parts of the forest trees were burned to ashes andtested. Each small part was examined to learn whether there were minerals in it. Study of the roots, branches and seeds showed no silver. But there were small amount of gold in the roots and a little less gold in the branches and seeds. The seeds growing nearest to the tree trunk had more gold than those growing on the ends of the branches. If the trees indicated that there was no gold in the ground, the scientists wouldn't spare money to pay for digging into the ground. Question: Which of the following might be the best title for this passage? Answer:
A:
output:
A new method of searching for minerals.
