Fortunately for early humans,the huge primate's diet consisted mainly of bamboo. Scientists have known about Gigantopithecus since some of its teeth were discovered on sale in a Hong Kong pharmacy about 80 years ago.The idea of a giant ape aroused the interest of scientists around the world,but It remained unclear when this beast became extinct. Now Jack Rink,a geochronologist at McMaster University in Canada,has used a high-precision -dating method to determine that this ape-the largest primate ever--roamed Southeast Asia for nearly a million years before the species died out 100,000 years ago.By this time,humans had existed for a million years. "Gigantopithecus is a primate that co-existed with humans at a time when humans were undergoing a major evolutionary change,"said Rink. Some of Gigantopithecus fossils were found in Guangxi.It is the region where some believe the modem human race originated.according to Rink.Scientists have been able to piece together a description of Gigantopithecus using just a handful of teeth and a set of jawbones. "The size of these specimens--the crown of the molar,for instance,measures about an inch (2.54 cm)across--helped us understand the extraordinary size of the primate,"Rink said. Scientists can only guess at what killed off a beast this size.Some scientists believe that a diet of bamboo combined with increasing competition from more nimble humans eventually led to its extinction. While most scientists agree that Gigantopithecus died out long ago,some people--Big-foot and Yeti enthusiasts in particular-believe that this ape is the source of tales of giant,hairy beasts living in the woods. Even though mainstream scientists dismiss these claims,it isn't impossible.The coelacanth a type of fish thought to have died out millions of years ago-was discovered swimming off the coast of Africa in 193& What's the best title for the passage?

Where do dogs come from? Gray wolves are their ancestors. Scientists are pretty consistent about that. And researchers have suggested that dogs' origins can date back to Europe, the Near East, Siberia and South China. Central Asia is the newest and best candidate, according to a large study of dogs from around the world. Laura M. Shannon and Adam R. Boyko at Cornell University, and an international group of other scientists, studied not only purebred dogs, but also street or village dogs. Dr. Shannon analyzed three different kinds of DNA, Dr. Boyko said, the first time this has been done for such a large and diverse group of dogs from 38 countries. And that led them to Central Asia as the place of origin for dogs in much the same way that genetic studies have located the origin of modern humans in East Africa. The analysis, Dr. Boyko said, pointed to Central Asia, as the place where "all the dogs alive today" come from. The data did not allow precise dating of the origin, he said, but showed it occurred at least 15,000 years ago. Greger Larson of Oxford University, who is leading a large international effort to analyze ancient DNA from fossilized bones, said he was impressed by the study. "It's really great to see not just the number of street dogs, but also the geographic breadth and the number of remote locations where the dogs were sampled," he said in an email. He also praised the sampling of different kinds of DNA and the analytic methods. Dr. Larson, who was not involved with the study, said he thought the Central Asia finding required further testing. He said he suspected that the origins of modern dogs were "extremely messy" and that no amount of sampling of living populations will be definitive. He said a combination of studies of modern and ancient DNA is necessary. Who wasn't engaged in the study of dogs' origins? A) Laura M. Shannon B) Adam R. Boyko C) Shannon and Boyko D) Greger Larson

A recent research shows that most people while attending their very first or second interview face the problem of interview nerves. This interview nerves simply make them nervous and depressed. This mainly happens due to lack of confidence and belief in oneself. Most of them even suffer from sleepless nights. They feel as if interviews are nothing but a questioning by an unknown person who will judge them by their answers. They simply can't understand or _ that the interviews are as beneficial for them as for the company. To overcome these problems, people need to make their mind set for facing the interview full of confidence. This can be done by building up confidence that this job is for me only. They need to make preparations for the estimated questions to be asked in the interview. They also need to be familiar with a few details of the company like its products, vision, recent achievement, etc. This is just to have an upper hand in the interview so that you can explain that you are the right candidate for the company. One must be completely relaxed before the interview. Because stress is one of the major reasons which reduces one's performance ability. Another way of getting over with your nerves is by a well known therapy called as hypnosis. Hypnosis is a very effective therapy which is generally used for curing nerves of Examinations, Interviews, Meetings, etc. Hypnosis mainly activates your subconscious mind so that you are extra alert and attentive what you are doing. Thus this gives you a lot more confidence to deal with. Now here are some of the tips you must follow for your interview. * You must be fully prepared for the interview and you must possess everything required. * You must maintain a complete eye contact with the interviewer, because it will show your confidence. * You must not do any nervous acts like being fidgety, fixing your tie or touching your clothes dress again and again. * Be positive while talking and use your hands to express yourself. * With hypnosis you can come in terms... What's the purpose of the passage _ ? A) To help overcome interview nerves B) To tell people the meaning of interview nerves C) To tell people how to attend interviews D) To help people become more confident
