input with options: Read the following article and answer the question. Article: Due to the increasing number of violence acts produced in schools all over the world, more and more parents prefer to have their children educated at home rather than at school. This way they can ensure their safety and well-being, although teachers and school representatives are trying to improve the situation in schools by increasing the number of the persons in charge of the safety of the students. The main reason for violence acts are the films and cartoons that fill the children's time. They want to do everything they watch on TV and never think of the consequences, and they may hurt a classmate or a teacher. On the other hand, parents are not fully satisfied with the children's results obtained in classes and they consider private classes would have better results. When a teacher has to watch 30 students in class he can't probably see what each of them is doing, how he is writing, or if he understands the explanations. At home the teacher can explain in details everything the child doesn't understand as many times as he considers proper. And many times the child grows fond of the teacher at home, who becomes his best friend, and who helps him whenever he needs someone to talk to. However, the best solution would be a mixture between the education received at school and that at home, because school makes children communicate and socialize. Keeping a child at home for fear there might happen something bad to him only makes the child's character weak and prevents him from knowing what real life is. Staying in _ only does harm to the child. All in all, schools have been created to help children, not to harm them, so it's best to keep children in these special places, where they learn, laugh, have fun and make new friends Question: What does "a crystal ball" in the passage refer to?

- A safe and comfortable environment
- A round object that is made of crystal

input with options: Read the following article and answer the question. Article: Goals can help you do, be and experience everything you want in life. Instead of just letting life happen to you, goals allow you to make your life happen. Successful and happy people have an idea of how their life should be and they set lots of goals to help them succeed. By setting goals you are taking control of your life. It's like having a map to show you where you want to go. Think of it this way. There are two drivers. One has a destination in mind which is laid out for her on a map. She can drive straight there without any wasted time or wrong turns. The other driver has no goal or destination or map. She starts off at the same time from the same place as the first driver, but she drives without an aim around, never getting anywhere, just using up gas and oil. Which driver do you want to be? Winners in life set goals and follow through on them. Winners decide what they want in life and then get there by making plans and setting goals. Unsuccessful people just let life happen by accident. Goals aren't difficult to set--and they aren't difficult to reach. It's up to you to find out what your goals and ideals really are. Research tells us that when we write a goal down, we are more likely to achieve. Written goals can be reviewed regularly,and have more power. Like a contract with yourself, they are harder to neglect or forget. Also when you write your goals in a particular way, you are able to make yourself be continuously alert to situations that will further your goals. Question: According to the passage, successful people are different from unsuccessful ones because _ . Answer:
OPTIONS:
- the successful people set goals for everything and can get help from others
- the unsuccessful people always set unrealistic plans for themselves
- the successful people set goals in their lives and make plans to carry it out
- the unsuccessful people make plans for everything but can not work hard
output: the successful people set goals in their lives and make plans to carry it out

input with options: Read the following article and answer the question. Article: Dozens of dolphins swam out of the polluted waters of Haifa Harbor on Tuesday.This was the first time that dolphins had visited this crowded Mediterranean port,and researchers were surprised and delighted by the unexpected event. Between 40 and 50 of the dolphins appeared in the busy port on Tuesday morning,obviously drawn by the fishrich waters of Haifa Harbor. However,the bay is also full of harmful chemicals. Aviad Sheinin,professor of Haifa University's Maritime Studies Department,said he didn't think the dolphins were harmed by the pollution,but he hoped that they would swim back to the sea soon. "It seems that they are quite relaxed. They don't seem to be stressed," he said. Haifa Harbor is lined by chemical companies that have been pouring poisonous waste into the water for decades. While pollution levels have dropped in recent years,the water is still considered a health hazard. "There are lots of fish in Haifa Harbor. Unfortunately we couldn't tell the dolphins that the fish are not healthy;and I don't know what the result will be," he told Israel Army Radio.Hundreds of Haifa residents gathered around Haifa Harbor to see the interesting sight,and researchers said this provided a rare chance to film and study the roughtoothed dolphins. In addition to the dozens of dolphins which swam into the port on Tuesday,a similar number stayed outside the breakwater .Later Tuesday the dolphins left the port but remained near the entrance and Israel's coast guard was patrolling the area to try to make sure the dolphins didn't reenter the poisonous waters. Relatively little is known about roughtoothed dolphins,which are usually found in deep and warm tropical waters. Question: Aviad Sheinin's words suggest that _ . Answer:
OPTIONS:
- the dolphins might affect the existence of fishes in Haifa port
- he is curious about the dolphins
- he will do research on the dolphins
- he is uncertain about what will happen to the dolphins
output:
he is uncertain about what will happen to the dolphins
