Astronomers have captured the first direct image of a planet being born. Adam Kraus, of the University of Hawaii's Institute for Astronomy, said the planet is being formed out of dust and gas circling a 2-million-yea-old star about 450 light years from Earth. The planet itself, based on scientific models of how planets form, is believed to have started taking shape about 50,000 to 100,000 years ago. Called LkCa 15b, it's the youngest planet ever observed. The previous record holder was about five times older. Kraus and his colleague, Michael Ireland from Macquarie University and the Australian Astronomical Observatory, used Keck telescopes on Mauna Kea(a volcano on the island of Hawaii, US) to find the planet. Kraus presented the discovery Wednesday at NASA's Goddard Space Flight Center in Maryland. Observing planets while they're forming can help scientists answer questions like weather planets form early in the life of a star or later, and whether they form relatively close to stars or father away. Planets can change orbits after forming, so it's difficult to answer such questions by studying older planets. "These very basic questions of when and where are best answered when you can actually see the planet forming, as the process is happening right now," Kraus said. Scientists hadn't been able to see such young planets before because the stars they're circling around outshine them. Kraus and Ireland used two techniques to overcome this problem.[:++] One method, which is also used by other astronomers, was to change the shape of the telescope mirrors to remove light distortion created by the Earth's atmosphere. The other method they used, which was unique, was to put masks with several holes over most of the telescope mirrors. The combination of these techniques allowed the astronomers to obtain high-quality images that let them see the planet next to the bright star. The star LkCa 15--the planet is named after its star--was the team's second target. They immediately knew they were seeing something new,... Which of the following would be the best title for the text? A) Youngest planet seen as it's forming. B) Planet 450 light years away discovered. C) World's first direct image of a planet taken. D) New technique helps discover young planets.

Ques: Plants need green leaves to make food. A plant needs sunlight and carbon dioxide from the air for making food and it also needs water and salts from the soil to make food too. There are certain cells in the leaves which change carbon dioxide and water into sugar. To do this the cells needs energy, which they get from the sunlight. Green leaves make food for the whole plant. A red leaf can make food too because under the red color1ing of the leaf there are food----making cells. There are no leaves which are completely yellow, for they can't make food. The plant makes sugar for its food. In sunlight green leaves make a lot of sugar. The veins can't carry all this sugar away, so the leaves change the sugar into starch , which is kept and so stored in the leaves. At night, the starch changes back to sugar. It is then carried away from the leaves. Some of the sugar is used as food by the plant while the rest is stored as starch. In some plants, food is stored in the roots, in others it is stored in the stem and in leaves, fruits and seeds. Which of the following best gives the main idea of this passage? _ . A) How green plants make food. B) How green plants make sugar. C) How green plants get their energy. D) How green plants change sugar into starch.

It's become part of the restaurant table setting: knife, fork, napkin and cell phone. Distracted dining is the new concern with customers constantly texting friends, uploading a Weibo photo of the meal they're about to chew down or emailing the boss. For many smart-phone users, it's hard just to focus on the meal and company at hand. Now, one restaurant in Los Angeles is giving diners a reason to turn off the digital world, by offering customers willing to check their phones at the door a 5-percent discount on their bill. Owner and chef Mark Gold of Eva Restaurant, located on Beverly Boulevard near N. Gardner Street, hopes this gives customers a way to truly sit back and relax, enjoy their meal and actually talk with friends and family in person. "For us, it's really not about people disturbing other guests. Eva is home, and we want to create that environment of home, and we want people to connect again," he explained. "It's about two people sitting together and just connecting, without the distraction of a phone, and we're trying to create an atmosphere where you come in and really enjoy the experience and the food and the company." Gold said applying the suggestion reminds him to avoid cell phone usage, too. "I'm guilty of it as well. When my wife and I go to dinner it seems like the cell phone is part of the table setting now. Every table you look at, it's a wine glass, the silverware and the cell phone," he joked. The husband and wife team runs Eva, a 40-person space with European flair. Gold said a little less than half take advantage of the deal, and no one has gotten upset about it. "I think once the server approaches the table and they're presented with the offer, they like the idea of actually talking to each other again," he said. What can be the best title of the passage? A) No Cellphone at Table! B) Focus on Your Cellphone! C) Eva Restaurant - Home to Customers. D) Talk Face to Face.
