Read the article and select the best answer. Article: A volcanic eruption in Iceland has sent ash across northern Europe Airlines have stopped or changed the flights across the Atlantic Ocean, leaving hundreds of passengers stuck in airports. Grimsvom is one of the largest and most active volcanoes in Europe. What makes Grimsvom different is that it lies under a huge glacier of ice up to 12 maters thick. The hot volcano heats up the ice above it, which then forms a layer of water between the glacier and the volcano This layer of water puts pressure on the volcano, keeping it stable, As the water flows out from under the glacier, the pressure lifts. The lava from the volcano then comes up to the surface. This is exactly what happened today. Now, airlines have to make changes to their flights so as not to fly through the clouds of volcanic ash. according to KLM, one of Europe's biggest airlines, airplanes cannot go under the cloud or over it. Going through the cloud can result in ash getting stuck in the airplane's engines, causing damage to the plane. The eruption has also caused problems for animals in Iceland. The volcano left ash and sharp. Glass-like rocks all over the countryside. Farmers are keeping their animals inside to stop them from eating ash--covered grass to the sharp object. Question: What makes Grimsvom different from other volcanoes? Options: A: It is below ice. B: It lies under the sea C: It is the largest volcano D: It is lava affects the airlines

Read the article and select the best answer. Article: Monitoring the mood of a pet dog could be used as an early warning sign that an elderly owner is struggling to cope, a new report has claimed. Researchers placed movement sensors on dogs to track their behaviour and identified 17 distinct activities, including chewing, barking, sitting and digging. This allowed them to map the normal behaviour of a healthy, happy dog, which means any changes can be monitored and could indicate an issue with their owner. Nils Hammerla, part of the team from Newcastle University, said, "Humans and dogs have lived together in close relationships for thousands of years, which has led to strong emotional and social mutual bonds." "A dog's physical and emotional dependence on their owner means that their well-being is likely to reflect that of their owner. Any changes such as the dog being walked less often, perhaps not being fed regularly, or simply demonstrating "unhappy" behaviour could be an early indicator for families that an older relative needs help. This is the first system of its kind which allows us to remotely monitor a dog's behaviour in its natural setting." The team of academics, who presented their findings at the 2013 UbiComp conference in Zurich, created a hi-tech, waterproof dog collar for the study. Dr Cas Ladha, who led the study, said: "A lot of our research is focused on developing intelligent systems that can help older people to live independently for longer. But developing a system that _ family and carers that an older relative is well without intruding on the individual's privacy is difficult. This is just the first step but the idea behind this research is that it would allow us to support people without the need for cameras." A range of dogs was used for the study, as the team needed to map distinct behaviours that correlated between different breeds. Question: From the text, we know that Nils Hammerla _ . Options: A: led the study and identified 17 activities of dogs B: thinks some activities of dogs can reflect senior owners' health C: studied the relationship between humans and animals D: developed a hi-tech, waterproof dog collar

Ques: Read the article and select the best answer. Article: Q: On Facebook, my friends are a mix of real-life pals, former classmates, professional colleagues, extended-family members, and ... my mom. Mom is the first to like and comment on everything I post, which is annoying. I tried talking to her about it, but her feelings quickly got hurt, so I backed off. I know I can't block her, but now I don't want to post anything. How do I handle this? A: This is about Facebook, not your mom. The often-shrugged-off truth about social media is that nothing is private. It's easy to forget this, so in a way, you're lucky that your mom is reminding you. Everything you post--comments, likes, photos--is freely available to future friends, employers, lovers etc unless blocked. That said, you can ask Mom again nicely to tone it down. You can also customize your controls so she can't see everything you post. Q: In which situations am I required to make a phone call versus send a text message? A: A text is for information--time, date, news. It's for the stuff you can keep short and sweet. A phone call is for analysis, discussion, opinion, and, if you must, gossip. Q: I'm always on Facebook, so I just send messages to friends through the site. But when should I log off and send an e-mail? A: When you're serious about anything. Think of it as chatting with someone on a bus versus asking her to meet you for coffee. The former is good for casual conversation; the latter is personal and requires attention. Q: For which occasions should I mail paper invitations versus send e-mail ones? (E-cards are free and easy--what's not to love?!) A: Anything important needs a paper invitation. That's your baseline. So ask yourself: "Do I want people to dress up for this event?" If the answer is yes, dress up your invitation by making it printed instead of virtual. For more casual events and gatherings, e-card away. Q: Is using emoticons ever inappropriate to express a feeling or make a point in texts or e-mails? A: Emoticons are for fun. Is the message you're writing fun? Use an emoticon. Are you... Question: Which of the following is appropriate about using social media? Options: A: Sending texts to consult a doctor for surgery B: Carrying on casual conversations via emails. C: Emailing your boss with emoticons for promotion. D: Writing a formal invitation for a dress-up event.

Read the article and select the best answer. Article: Pupils work harder in lessons if they are taught by a man, a study has claimed. Male teachers are more likely to improve pupils' self-esteem and are judged by pupils to be more fair, according to a study published by the Department for Education. But there is a significant shortage of male teachers, especially in primary schools, with reports last month indicating that almost one in three primaries has an all-female teaching staff. The latest figures heightened fears that schools are becoming dominated by women and children are being denied access to male role models in the classroom. Researchers at the London School of Economics and Westminster University conducted an experiment in which each of 1,200 pupils in 29 schools was given PS2. They could use the money to "buy" up to 10 questions at a cost of 20p each, which they then had to answer. If they were right they were given an extra 20p, but if they were wrong they lost 20p. Boys and girls who had a male teacher chose on average almost half a question more than those taught by women, indicating that they had a more positive outlook on the rewards of effort, the the study said. Researchers wrote: "One of the most significant results featured in this experiment is the positive effect of male teachers on effort. The experiment suggests that higher ability pupils either believed that the teacher would reward them more favorably or had a preference for working hard to please the teacher." According to the Good Teacher Training Guide, 86 per cent of new teachers entering primary schools are female, along with 62 per cent of those entering secondary schools. Professor Alan Smithers, of Buckingham University, said: "This is an interesting and somewhat surprising finding, but it does underline the importance of having a good mix of male and female teachers in classes." Question: Which of the following is true of the passage? Options: A: Male teachers are more fair than female teachers. B: Now most primary schools are in need of teachers. C: Most people are afraid that their children can't get access to male teachers. D: The author thinks that male teachers are better than female teachers.
