Q: Read the following article and answer the question. Article: We Chat, the Chinese social media smartphone app, saw an increase in user numbers of 41 per cent year on year to 500m at the end of 2014, in a sign that parent company Tencent is extending its reach for the mobile internet. Revenue grew 24 per cent to Rmb20.98billion, slightly higher than forecasts, driven mainly by online gaming revenues. It is unclear how much WeChat contributed to Tencent's revenues but the app's growth is a strong indicator of the company's long-term health as it tries to adjust its business to be more suitable for mobile devices. "We extended our leadership in games and online media, and made breakthroughs in emerging platforms such as online security . . . and mobile payments," Ma Huateng, Tencent chairman, said in a statement. WeChat is the second highest ranked app in China, behind QQ, Tencent's other chatting app, which claimed to have 815m registered monthly users at the end of 2014. However, that figure is more than the total number of internet users in China, which the government puts at 640million. Tencent has been unwilling to earn money through WeChat by flooding it with advertising, which could reduce efforts to increase the user base. But this is expected to change. Some analysts predicted that advertising would be introduced on later this year. Early attempts to test ads on the service have not always gone smoothly. After a BMW ad was introduced on some users' feeds in January, many users complained of "discrimination" by Tencent's data mining algorithm. They said it unfairly considered them as not wealthy or successful enough to view the sought-after BMW ad. Question: What can we learn from the passage? Answer:

OPTIONS:
- WeChat contributed most to Tencent's profits.
- WeChat is ranked behind app QQ in China.
- Tencent wants to earn more through QQ
- More advertising would not be introduced later this year.

A: WeChat is ranked behind app QQ in China.

Q: Read the following article and answer the question. Article: What would you do if you were lost in the dark forest at night? The first sensible lesson is that you shouldn't bother trying to find your way in the dark at all, but just stay put until dawn. Because then you won't trip over things? No, mainly because you'll have an idea of direction. The sun rises in the east. But you will be amazed at how many people forget they know that. Apparently, the area underneath a holly bush provides a good makeshift shelter -- they are thick, and evergreen. The next thing to do -- or rather not to do -- is panic, for the obvious reason that unless there is someone there to hear you scream, it will get you nowhere. Just try to think of nice, happy things. There is always a point in films when a person who is lost in the desert or the snow, dehydrated and exhausted, comes across a set of their own footprints and realizes they have just walked in a huge, round circle. It is wrong to owe it to the unequal strengths or different lengths of your legs. Experiments prove that, without the sun or the moon (or landmarks) as a fixed guide, lots of small errors add up over time so the brain can't correctly identify the "straight ahead" direction. To just get out of somewhere, pick a spot on the horizon and just head for it. There are several ways to find directions in the dark, and by far the best is to establish north using the stars. Most people can identify the Plough, which is part of Ursa Major. It looks a lot like a saucepan. The Plough rotates through the sky, but let's imagine the saucepan lying horizontally , with its handle on the left. You need to trace a line from the star at the right-hand base of the pan, through the star at the right-hand rim , and follow it upwards; the north star is roughly five times the distance between those two "pointer" stars. Then drop a vertical line from the North Star to the horizon and that's north. "Tonight is very cloudy and I can't see the Plough." Maybe luckily, it is quite windy. Keep in mind that almost all of our weather comes from a... Question: Why will people often walk in a circle if they are lost in the desert or the snow? Answer:

OPTIONS:
- Because without anything to refer to for directions, the brain will be confused by errors.
- Because one of the legs is longer and stronger than the other.
- Because the desert or the snow usually covers a large area for people to get across.
- Because people usually feel dehydrated and exhausted in the desert or the snow.

A: Because without anything to refer to for directions, the brain will be confused by errors.

Q: Read the following article and answer the question. Article: John Fisher, a builder, and his wife Elizabeth wanted more living space, so they left their small flat for an old 40-meter-high castle tower. They have spent five years turning it into a beautiful home with six floors, winning three architectural prizes. "I love the space, and being private," Elizabeth says. "You feel separated from the world. If I am in the kitchen, which is 25 meters above the ground floor, and the doorbell rings, I don't have to answer it because visitors can't see I am in!" There are 142 steps to the top so if I go up and down five or six times a day, it's very good exercise! But having to carry heavy things to the top is terrible, so I never buy more than two bags of shopping from the supermarket at a time. Except for that, it's a brilliant place to live. "When we first saw the place, I asked my father's advice about buying it, because we couldn't decide. After paying for it, we were a bit worried because it looked awful. But we really loved it, and knew how we wanted it to look." "Living here can be difficult--yesterday I climbed a four-meter ladder to clean the windows. But when you stand on the roof you can see all the way out to the sea on a clear day, and that's a wonderful experience. I am really glad we moved. " Question: Which of the following best describes Elizabeth's feelings about the tower? Answer:

OPTIONS:
- She wanted it as soon as she saw it.
- She likes most things about it.
- She has been worried since they paid for it.
- She finds it unsuitable to live in.

A:
She likes most things about it.
