Read the following article and select the best answer. Article: While I was in my 4th month of pregnancy with my second child, we were preparing for a trip to Louisiana, where Marshall's family live, to celebrate Jane's 2nd birthday. Two days before we were to leave, we got the shocking news that I was going to lose the baby. Not knowing when this would happen, we decided to continue with our trip. Since Marshall's family lives on a 600-acre cattle farm, you often find that you have a lot of time to yourself to think when you are there. That is precisely what I did not want to do at this time. I told Marshall that I needed to get a good book to get lost in while I was there. I told him I heard the Harry Potter books were good, so he went out and got the first one for me. During that trip, I totally got lost in the book, which was of great help during a time when I needed a distraction to forget about the sadness. In the book, I noticed the name "Seamus". I vaguely remembered it was pronounced "Shamus" and I liked the sound of that. I mentioned it to Marshall and he liked it too. Toward the end of the trip, I had just 5 chapters left and I knew I was about to finish the first book, which I was pretty excited about. Soon after we put Jane down to bed, I had started labor , so I was unable to read. The labor lasted 5 and 1/2 hours, but Marshall stayed there with me, sitting beside me and reading aloud the last 5 chapters of Harry Potter. I can never fully explain how much that helped me through the experience. And ever since then, Marshall and I both have been fans of the Harry Potter books. We remember how they helped us get through that time of our lives. We were sad to have lost the baby, but the name Seamus started our journey toward adoption. And we gave this name to our adopted son. Though our Seamus doesn't have a drop of Irish blood in him, the name fits him perfectly. Question: According to the story, we can know that the Harry Potter books _ . - made the family's trip more exciting - include five books all together - have someone called Seamus in them - can help people deal with their problems
have someone called Seamus in them

Read the following article and select the best answer. Article: Orcas, or killer whales, are the largest of the dolphins and one of the world's most powerful animals feeding on meat. They feast on marine mammals such as seals, sea lions, and even whales, employing teeth that can be four inches (ten centimeters) long. They are known to grab seals right off the ice. They also eat fish, squid , and seabirds. Though they often frequent cold, coastal waters, orcas can be found from the polar regions to the Equator . Killer whales hunt in deadly groups, family groups of up to 40 individuals. There appear to be both permanent and temporary group populations of killer whales. These different groups may hunt different animals and use different techniques to catch them. Permanent groups tend to prefer fish, while temporary groups target marine mammals. All groups use effective, cooperative hunting techniques that some are similar to the behavior of wolf packs. Whales make a wide variety of communicative sounds, and each group has various noises that its members will recognize even at a distance. They use echolocation to communicate and hunt, making sounds that travel underwater until they meet objects, then reflect back, showing their location, size, and shape. Killer whales are protective of their young, and other adolescent females often assist the mother in caring for them. Mothers give birth every three to ten years, after a 17-month pregnancy. Killer whales are immediately recognizable by their special black-and-white coloring and are the intelligent, trainable stars of many aquarium shows. Killer whales have never been widely hunted by humans. Question: We can conclude that _ . - people can find killer whales everywhere around the world - killer whales live in different groups and never live alone - by making sounds killer whales hunt and communicate - humans' hunt has made killer whales being endangered
by making sounds killer whales hunt and communicate

Read the following article and select the best answer. Article: Exhausted and unhappy, you still have to squeeze a smile to your friends, or teachers. That's just life, you may think. But new research suggests that putting on a fake smile can worsen people's mood and even lower work efficiency. Lead researcher Brent Scott with other researchers studied a group of bus drivers for two weeks. They tried to find out what happened when the drivers were involved in "surface acting" or fake smiling, and the opposite, "deep acting" which means people put on real smiles by recalling pleasant memories or thinking about their current situation more positively. The results showed that on days when drivers were forced to smile, they felt depressed and didn't want to work. On days when they smiled due to positive thoughts, their mood improved a lot as well as their work efficiency. The research goes against the popular belief among companies that employees should be cheerful to customers at all times. They include employees of shops, banks, call center workers and others who have face-to-face contact with members of the public. "Smiling for the sake of smiling can lead to emotional exhaustion and coldness, and that's bad for the organization," Scott told the Daily Mail. The study also showed that women were harmed more by fake smiling than men. Their mood and work performance both worsened more. But they were helped more by deep acting -- their mood became better and they worked more efficiently. However, while deep acting seemed to improve mood in the short term, Scott says it's not a long-term solution for unhappiness. "There have been some suggestions that if you do this over a long period that you start to feel inauthentic ," Scott said. "You may be trying to cultivate positive emotions, but at the end of the day you may not feel like yourself anymore." Question: The article is mainly about _ . - the importance of smiling during face-to-face contact - a new study on fake smiling and its influence on people - suggestions on improving work efficiency - how to cheer up when you are exhausted
(Answer)
a new study on fake smiling and its influence on people
