I'm taking a test and have to guess the right answer to the question after the article. Article: It was the day after Halloween when my grandmother was admitted to the hospital with the worst headache she'd ever had. While posing in our costumes the night before, we knew something was wrong, just not how wrong. Grandma's house was the central gathering place of my family. Sunday lunches, birthday dinners, Easter, Thanksgiving, and Christmas -- all were our traditions, with her as hostess. While my parents were busy running their small business, there were many nights when Grandma fed me and put me to bed in her spare room, until they came to get me. I spent my summers at Grandma's and I went everywhere with her. I couldn't imagine a time when she wouldn't be around me. Then November 1, 1991 began her month-long stay in the hospital--she suffered from a rare infection called nocardia asteroides. After being born in the year of the Great Depression, living through World War II, raising three kids, and being widowed at the age of 48, Grandma never expected to live into her seventies. The infection in her brain seemed to confirm that she wasn't long for this world. But that's not the end of her story. A team of doctors successfully removed the abscess , and Grandma even made it into a local medical journal. Her doctor called her "the brain lady". Grandma celebrated her 85thbirthday in March this year. In the almost 23 years since her recovery, she's seen two of her four grandchildren get married and welcomed three great-grandsons. Although they damage something in her house, she loves it when my two boys come over. And while I know they make her day, seeing her love blossom for another generation makes my day too. Happy Grandparents' Day to my amazing grandmother! Question: When did Grandma have the operation to remove the abscess? Options: A: At the age of 60. B: When she was about 62. C: Before November 1, 1991. D: After this year's Halloween.

I'm taking a test and have to guess the right answer to the question after the article. Article: The Vienna-based researchers showed that dogs will stop doing a simple task when not rewarded if another dog, which continues to be rewarded, is present. The experiment consisted of taking pairs of dogs and getting them to present a paw for a reward.On giving this "handshake" the dogs received a piece of food.One of the dogs was then asked to shake hands, but received no food.The other dog continued to get the food when it was asked to perform the task. The dog without the reward quickly stopped doing the task, and showed signs of anger or stress when its partner was rewarded. To make sure that the experiment was really showing the interaction between the dogs rather than just the frustration of not being rewarded, a similar experiment was conducted where the dogs performed the task without the partner.Here they continued to present the paw for much longer. Dr Frederike Range from the University of Vienna says this shows that it was the presence of the rewarded partner that was the greater influence on their behaviour. "The only difference is one gets food and the other doesn't, they are responding to being unequally rewarded." she said. The researchers say this kind of behaviour, where one animal gets frustrated with what is happening with another, has only been observed in primates before. Studies with various types of monkeys and chimpanzees show they react not only to seeing their partners receiving rewards when they are not, but also to the type of reward. The dog study also looked at whether the type of reward made a difference.Dogs were given either bread or sausage, but seemed to react equally to either.Dr Range says this may be because they have been trained. Question: The dogs refused to give the paw when they _ . Options: A: found another dog was given nothing B: felt they were not treated equally C: were aware they received less food D: were given too much reward

I'm taking a test and have to guess the right answer to the question after the article. Article: Texting walkers aren't just an annoyance to other walkers, Australian researchers armed with movie special-effects technology have determined scientifically that they're threats to themselves. Using motion-capture technology similar to that used for films, researchers concluded that texting while walking not only affects balance but also the ability to walk in straight line. "Some people like checking emails while walking to work in the morning" said the study co-author Hoorn, "but they may not know it has a serious effect on the safety of themselves". Other facts have also proved this. A tourist from Taiwan walked off a pier near Melbourne last month while checking Facebook, bringing a sudden and icy end to a penguin-watching visit. Another person who was too _ in his phone to notice dangers walked straight into the fountain in front of a shopping mall. The Australian study involved 27 volunteers, a third of whom admitted having knocked into objects while texting. They were asked to walk 8.5 meters three times--once without phones, once while reading text and once while writing text, when eight cameras recorded their actions. They found the volunteers using the phone walked slower, and, more seriously, they locked their arms and elbows in like "robots", which forced their heads to move more, throwing themselves off balance. "In a pedestrian environment, inability to maintain a straight path would be likely to increase potential for traffic accidents", said Mr. Hoorn. "The best thing to do is to step aside and stop, or keep off the phone." Authorities world-wide have taken note. Signs on Hong Kong's subway system advise passengers in three languages to keep their eyes off their phones. Police and transport authorities have highlighted the danger in Singapore, where the Straits Times newspaper recently declared cellphone-distracted road crossing as "bad habit No. 2" contributing to the rising number of road deaths. Some U.S. states, including New York and Arkansas, are considering bans on what they're calling... Question: About the Australian study, we know that _ . Options: A: the volunteers using phones while walking moved normally B: ten volunteers admitted having bumped into things while texting C: the volunteers were divided into three groups during the study D: texting walkers are exposed to greater possibility of traffic accidents
