Albert Einstein died long ago. However, a group of researchers have created a robot which looks like the great scientist. The robotic Einstein is very special because the researchers at the University of California, San Diego (UCSD) have taught their realistic robot to smile, frown and make other complex facial expressions. Scientists believe that babies learn to control their bodies through movements, including learning to speak. "We use the same idea to work out the problem of how a robot could learn to make realistic facial expressions," said Javier Movellan, director of UCSD's machine Feeling Lab. ks5u The San Diego researchers directed the Einstein robot's head to turn in all directions. The robot could see its expressions in a mirror and then use the software to provide data for machine-learning to match facial expressions to the movements of its small motors. Once the robot learned the relationship between facial expressions and the muscle movements, it learned to make facial expressions. Its head has about 30 facial feelings, and each is moved by a tiny motor connected to ht e skin by s sting. Although we've never met Albert Einstein, we have a feeling that the new robot isn't exactly a fair representation of now of the best minds of the 20th century. The figure does not have the grace of the great man, but it can recognize human expressions and react to them in the right way. In fact, if you smile at it, it will smile right back to you. "As far as we know, no other research group has used a robot to make realistic facial expressions," said computer scientist Tingfan Wu, a computer science PhD student who worked on a more exact facial expression robot. This robot is special mainly because it _ . A) looks just like Albert Einstein B) can make various complex facial expressions C) can walk and talk to people D) can turn its head in all directions

Howling is a behavior commonly observed among a wolf nark. An animals, wolves work together to hunt and rely on howling was an important means of communication each other. There are different explants of a wolf's howl and it appears that there may be more to discover. One theory is that wolves howl to bend better together. It's almost as if howling together helps the pack stay together. Perhaps something similar to people feeling a sense of involvement with each other when singing a song together . But this theory may be wrong, explains Fred H. Harington, a professor who studies wolf behavior. Indeed, there have been tines when wolves have been seen one moment howling in a exhorts, and the next, quarreling anions each other. It appears that usually the lowest-tanking menthes of the pack may actually be "punished" for Joining in the churs at times. So is howling a way to strcagthen a social boad or just a way to reconfirm status among its members? ----Why do welves howl for sure? What is cleat, however, is that howling is often used among packmates to locate each other. Hunting grounds are distant and it happens that woloves may separate from one another at times. When this happens, howling appcars to be an ercellent means of gathering. Howling, interestingly, is a contagious behaviour. When one wolf starts to howl, very likely others will follow. This is often seen to occat in the morning, as if wolves were doing some sotr of "roll rall"where wolves all howl togeter to howl, very likely others will follow. This is often seen to occar in the morning, as if wolves were doing w some sotr of "roll call"where wolves all howl together to repotr their pteence. .Why does Harrington think the"secial boad"theory may be wrong? A) Wolves separate from each other after howling. B) Wolves tend to protect their hunting grounds. C) Wolves sometimes have quarrels after howling together. D) Wolves of low rank are encouraged to join in the chorus.

Ques: Imagine a picnic dinner held at a location only made known hours before the meal, where guests are invited to decorate tables and chairs, bring their favorite dishes and wear white to reflect the simplicity of the event. This was the scene at a PopUp dinner held on June 13 in Brooklyn, New York's Prospect Park. PopUp dinners are popping up nationwide -- not just in Brooklyn. Garrett Sathre and his wife and business partner, Nicole Benjamin-Sathre are the team behind Hand Made Events and the creators and hosts of PopUp dinners. Sathre, a former restaurateur and head chef with Bubba's Diner and Kitchen 39, both located in the Bay Area, came up with the concept of the flash dinner after he was inspired by the annual Diner en Blanc held in Paris. In 2011, Hand Made Events used the power of social media to get the word out and soon, enough interest was attracted. In October 2011, it held its first flash dinner, calling the evening Le Diner a San Francisco at Golden Gate Park's outdoor Music Pavilion. He described it as a picnic dinner for 3,500 people."I thought we would have anywhere between 300-500 people to attend. Two articles ran a week later about my crazy idea and we got 15,000 emails within three days,"Sathre said. After the success of the San Francisco dinner, Sathre decided to expand his"crazy idea"and hold dinners across the country in major markets such as Brooklyn, Los Angeles and San Francisco. Sathre says their Brooklyn PopUp on June 13 sold 5,000 tickets in just four days with 5,000 on the waiting list raising over $160,000 in ticket sales. Those are some big numbers. Hand Made Events partners with the Prospect Park Alliance and gives all of their proceeds to the non-profit group. In total, the Brooklyn PopUp dinner raised over $60,000 for the Prospect Park Alliance. Hand Made Events sees the same interest in their smaller city locations."We have seen a 30 percent increase in our smaller markets -- Minneapolis, San Diego, Charleston, and Miami every year,"Sathre said. Hand Made Events has eight... We can learn from the passage that Hand Made Events . A) is an organization which helps the homeless and the poor B) is made up of about 500 volunteers around the world C) has already held several dinners in some smaller cities D) intends to collect money for non-profit groups
