Article: A growing number of Chinese are keeping their cash in their wallets this Lunar New Year as the traditional exchange of red packets of money is moving from the physical world into the digital space. The tradition of giving cash gifts of "lucky money" ("hong bao" in Chinese) goes back centuries and can be particularly profitable for the young and the unmarried. As the country increasingly adopts online business and e-commerce models, tradition is taking a back seat to convenience as more and more lucky money receivers prefer to receive their money via electronic means. A recent study conducted by Shanghai-based Avanti Rhesearch Partner showed that 58% of respondents preferred their hong bao directly deposited into their accounts. The country is becoming increasingly connected --- over 90% of 18 to 30 year olds in China own an Internet-connected smart phone, according to a Global Times survey published last year. Of course, China's Internet giants have not been slow to capitalize on this trend, with Shenzhen-based Tencent last week launching their "New Year Red Envelope" app , an add-on to its popular WeChat messaging service. The company's over 600 million WeChat users can send each other lucky money, provided both the sender and receiver have signed up to the company's in-app payment service. "I am really happy that I can use a new and fashionable way to send my holiday greetings to my family and friends, especially for people who have kids but live far away from us." said Mr. Cheng, a user of the service. The service reportedly banked 18 million RMB ($2.9 million) worth of transfers in its first 24 hours, according to a report in the Beijing Youth Daily newspaper. While Tencent's rival Alibaba also has a similar service, called Hong Bao, which launched last year, WeChat's app allows users to randomly distribute up to 200 yuan ($33) within a group of friends, adding a fun element of unpredictability to the process. Some analysts believe that linking the payments to WeChat's in-app payment service could be a game-changer, as it simplifies the process of paying for micro dealings, potentially making users more likely to make in-app purchases in the future. "The tradition of giving red packets is a symbolic gesture," said Steve Wang, Chief Economist, Reorient Group. "It's a new way to get people more comfortable dealing with money online, to expand their user base. It combines the old and the new, and is a great example of the kind of creative idea that we're seeing come out of China these days."
Answer: New Year luck money goes online.

question:
Article: One day, around Christmas time, fishermen off the west coast of Peru started on their traditional fishing trip. Much to their surprise, there were no fish! They knew immediately what had happened. Tales from years gone by had told them this was the result of El Nino which sometimes stop fishing for many months! El Nino is a warm _ that comes and goes along the west coast of South America. It got its name from fishermen in Peru more than a century ago. Every few years, they noticed a sudden warming in the normally cool Pacific water where they fished. Because this warming often came about around Christmas, they called it El Nino, which is Spanish for the "Christ Child". Generally, El Nino occurs every three to seven years and lasts only a few weeks to a month or more. El Nino warms the water it flows through. Because the fish and sea birds need cold water to live, many of them die when El Nino comes through. El Nino also causes both floods and droughts. It is believed that El Nino may have caused the 1993 Mississippi and 1995 California floods. And at the same time, it may have caused droughts in South America, Africa and Australia. El Nino has occurred thirteen times within the last fifty years, bringing natural disasters to many countries such as Indonesia and Peru. However, El Nino does not often trouble China. During this period China was badly hit by El Nino only once. In 1998, North China had a terrible drought, while South China was troubled by floods.
Answer: It lasts a few weeks or more.
answer:
According to the passage, which of the following is TRUE about El Nino?

Article: Just when scientists think they have discovered and recorded every species of insect that crawls on the earth they find something new.Earlier this month, Peter Jager, the head of Frankfurt's Senckenberg Research Institute reported the discovery of a unique eyeless spider! The creature that has a leg span of six centimeters and a body size of just twelve millimeters was found in a cave inside the tiny nation of Laos, in Southeast Asia. It was identified as a member of the Huntsman spider, a large family that consists of 1100 species.However, the other members of the family all have eyes.The spider is the first one that has no eyes.The scientists believe that the reason for the lack of eyes can be that these spiders spend their entire life inside caves.In the past they have seen other members of the Huntsman spiders living in caves with six or less eyes.They believe that the kind of spider has adapted to the fact that they do not really need the eyes to such an extreme measure that they have _ them altogether. But they are not the only creature to have done that.Over the years, scientists have discovered completely blind cave fish, and even a freshwater crab, which happens to live in the same cave as this eyeless spider! Surrounded by Burma and China on the northwest, Vietnam on the east, Cambodia on the South and Thailand on the west, the landlocked nation of Laos has been a treasure trove of an incredible number of new and exotic species.In the last few years researchers have discovered the Saola -- never-before seen antelope-like creature, a small deer species called muntjacs, a tiny striped rabbit and a rock rat that was thought to have been extinct 11 million years ago.In addition to that it is also home to over one hundred species of large mammals ranging from tigers to macaques and over 165 species of amphibians and reptiles like the terrible King cobra and the noisy Tokay gecko, a permanent resident inside most Laos households.
Answer: About 1100 such spiders were discovered.
answer:
What can we know about the newly discovered species of spider?
