Read the following article and answer the question. Article: Dolphins are interesting animals and researchers find them interesting to watch. They don't have hands, but can use tools to solve problems, just like us. Scientists have observed a dolphin trying to get a shy eel to come out of its hole by poking it with a dead fish. Many species of dolphin live in large societies. They have many different relationships and need a good communication system; they use a variety of sounds to communicate with each other. There is currently no evidence that dolphins have a language of their own. But scientists still have a lot to find out about these animals and so there are certain to be a few surprises in the future. At Kewalo Basin Marine Laboratory in Hawaii, the dolphin team have developed a sign langue to communicate with the dolphins, and the results are amazing. Not only do the dolphins understand the meaning of individual words, they also understand the significance of word order in a sentence. For example, when they were asked to 'touch the ball with your tail and then jump over it' they generally responded correctly and straight away, which showed that they understood the langue. Most mammals seem to enjoy play--but dolphins seems to like making their games as challenging as possible. On a beautiful day in 1997, researchers working at a beach, off the southern coast of Brazil, observed a little dog going into the sea and swimming towards the dolphins. To their surprise, the dolphins approached the dog and then started throwing it into the air. The dog seemed to enjoy the 'game' and continued playing with the dolphins for more than an hour. From then on, different dogs were seem trying to interact with the dolphins. Dolphins live in a very different world to ourselves, but they are very good at our 'intelligence tests'. For example, they will jump out of the water when they hear a whistle noise. They do this because they will get a fish as a reward. There is still much to learn about these flexible problem-solvers, but from the evidence so far, it would seem as though... Question: Dolphins not only understand the meaning of individual words, they also understand the importance of _ in a sentence. Answer:

OPTIONS:
- the subject
- the verbs
- the main structure
- word order

Answer: word order

Read the following article and answer the question. Article: I live in a big Scandinavian city that unluckily has a lot of homeless people. But there are many ways of helping them even though you may not have a lot of money. One way is to buy their monthly magazines. By doing this one day, I got to know a young homeless man who was often standing at the train station, selling the magazine. He was from another country and I can only imagine what kind of psychological scars he must have had from living in a war-torn country. After a while, I found that his birthday was close to mine which meant that we were born under the same sign of the Zodiac . I met him last year shortly after his birthday, and without thinking, after congratulating him, I asked if he had had a good day. He said he hadn't really celebrated. I just couldn't bear the thought of this nice, young man being alone on his 25th birthday with no presents, no cakes and no songs! So I went home and looked in my yarn basket and as luck would have it, I had two yarn cores of pure wool left. I set to work and knitted a scarf for the young man. I ran into him on my own birthday the next year as I was going shopping. I had hoped to meet him so I had carried the scarf around with me and a piece of my own birthday cake. He was very happy with these gifts and so was I. The light in his eyes and the heartfelt hug he gave me was the best present he could have given me! Question: It can be inferred that _ . Answer:

OPTIONS:
- the writer was very warm-hearted and she liked helping others
- the writer regretted not celebrating her birthday with the young man last year
- the young homeless man enjoyed himself on his birthday party last year
- the young homeless man was begging at the train station

Answer: the writer was very warm-hearted and she liked helping others

Read the following article and answer the question. Article: My high school life has been filled with many ups and downs, whether it was social or academic. Even though my current high school was not my first choice, I never regretted attending Southside High School. "Since you have chosen it, then it is the best for you," said my parents. Up until the junior year I did not realize my capabilities as a student. Being in the IB Program, I was told that my junior year would be the toughest in all the years of high school. With this "little" piece of information, I walked into my junior year, scared of my grades. As weeks went by, I started to believe that the junior year was not as hard as everyone had said, but I was wrong. My grades were rapidly declining and by the end of the first term I had had five Cs in seven of my classes! I could not believe it --- I did not want to believe it. I tried my best to get my grades up myself without any help from anyone, but my pride just made my grades worse. And I had to miss out on one of the most important speech and debate competitions all year: States. I was heartbroken. I realized that I could not survive my junior year on my own, so I had to get help fast. Once I got a tutor, my grades went from Cs, Ds, and even some Fs, to nothing but As and Bs. I slowly started to gain my confidence back in all of my classes and even myself. By the time the third and fourth quarter came around, I had been on the honor roll twice, and I was receiving awards from speeches and debates, tennis and school. Southside has taught me to always keep my head up and never give up on myself no matter what life throws at me. I am proud to be a Southside Tiger. Question: How did the writer feel when she walked into her junior year? Answer:

OPTIONS:
- Confident.
- Worried
- Curious.
- Uninterested.

Answer: Worried

Read the following article and answer the question. Article: Losing a baby tooth can be fun for a kid. You can put it under your pillow and look forward to finding some money there in the morning. And then you can watch your new permanent tooth grow in its place. But if a permanent tooth falls out, that's a problem. There isn't another one under the gum that can replace it. Unfortunately, this happens to some older people. And if permanent teeth fall out-or need to be pulled-an older person might need dentures. Dentures, known as false teeth, are a set of replacement teeth for any teeth that are missing. There are partial dentures, which take the place of only a few teeth and prevent the others from changing position. If all the teeth are gone, the person would need complete dentures, which replace every tooth in the mouth. Dentures can cause pains at first and take little time to get adjusted to. They also need special care. They should be brushed daily with a special denture brush and cleanser and soaked in denture solution when not in the mouth. Dentures are important for older folks because, without teeth, it's hard to smile, talk, and eat properly. But it can be a little _ if you see someone take out his or her dentures. It can also be strange to see someone, like a grandparent, without dentures in because he or she won't have any teeth. Try not to make fun of the person because this could cause hurt feelings. People usually lose their permanent teeth due to periodontal disease, or gum disease, which is caused by bacteria that attacks the gums. Diseased gums aren't strong and healthy, so teeth can get loose and fall out. Older people often have many cavities that have been filled over the years, and these fillings can weaken over time, leading to more tooth decay. Question: If one of your baby teeth falls out, you_. Answer:

OPTIONS:
- should have a false tooth fixed in its place
- have to put it under your pillow at once
- will gain a permanent tooth in future
- can exchange it for some money

Answer:
will gain a permanent tooth in future
