Question: Article: There is a huge demand for shark fins in Asian countries. As a result, many sharks are caught and killed. In Palau, where more than half of tourists are drawn by diving excursions, each reef shark brings in about $179,000 in tourism revenue annually, or about $1.9 million during its lifetime. Due to overexploitation and lack of proper management, many shark species are under considerable risk of unrecoverable decline with some species having declined to near extinction in recent years. According to reports, sharks are being killed at an alarming rate of up to 273 million worldwide per year. Some experts predict that if the killing continues at the current rate many shark species will be lost forever. It can be very dangerous. Sharks are very important and they should be protected. In a study of the east coast of the United States, 11 species of sharks were eliminated from their range. Of the 14 species of ocean life that those sharks used to eat, the populations of 12 exploded and caused great damage to the ecosystem. For example, the cownose ray population was no longer kept under control by sharks and so grew out of control. As a result, the rays destroyed the population of bay scallops , their favorite food. The scallop fishery, which had been in good condition for over 100 years, was wiped out. Also, the removal of the scallops most likely had an effect on water quality as they were no longer there to perform their function of cleaning the water. Sharks play a vital role in the oceans in a way that the average fish does not. Most sharks serve as top predators at the pinnacle of the marine food pyramid, and so play a critical role in ocean ecosystems. Directly or indirectly they regulate the natural balance of these ecosystems. Sharks tend to eat very efficiently, going after the old, sick, or slower fish in a population, keeping that population healthy. Sharks help keep many populations of ocean life to the right size so that those prey species don't cause harm to the ecosystem by becoming too... Question: After the number of cownose rays greatly increased, . Yes or no, is the answer "the local scallop fishery was harmed"?
Answer: No

Question: Article: We live in central Phoenix, near the canal. Every day I used to see a homeless old man and his scruffy little dog hanging out down there. I would tell my husband we should give him food for the little dog. It wouldn't have been a problem; we have our own "mini farm" of animals! But he would say "OK!" and then blow the idea off because of our business. Being in Phoenix, Arizona, you can just imagine how hot it gets here, but his winter was really chilly! I had just come from KFC with take-out food for dinner. As I was turning by the canal, the man and his dog were sitting right there all bundled up. Even the doggy had a coat on! Not even thinking about it, I pulled into the parking lot along the canal and piled up a plate of chicken with all the fixings for the man and his little buddy. I gave it to him with a soda and a bottle of water for the little dog. He said, "Thank you, sweetie. You are an angel." And there were tears welling up in his eyes! I told him he was so welcome, and then went home. When my husband dug into the KFC gag, he asked, "Were you hungry, or what?" I told him what I did and he said, "Only you!" Then he told me I had done a good thing. A few weeks later, we were walking along the canal and found the man walking to me, with his little dog. He asked whether I would mind adopting the dog. With tears in eyes, he said it had gotten too hard for him to care for the dog. He added that he was planning on heading to Washington State but his dog wouldn't have been up to it, so he hoped to give it to me. "Only you! In this city, you are the only person I can believe in!" Now, every time I watch and pat the puppy lying near the fireplace, I will recall the old man's words and wish him good luck. Question: The author and her husband didn't help the old man at the beginning because _ . Yes or no, is the answer "they worked busily and often forget it"?
Answer: Yes

Question: Article: At first Kate thought the Romanian girl could not speak and understand English. Nadia would not reply to anything Kate said. Kate was in charge of showing Nadia around on her first day at Buck Minister Grade School. Kate could not figure out why the school had put Nadia in a class where she could not understand what people were saying. "Why did they do this?" Kate wondered aloud. "I mean, you can't learn if you can't understand the teacher." Nadia's voice was a whisper (speaking in a very low voice). "I understand English. I will learn." Nadia's English was perfect. Kate was _ . She couldn't understand why Nadia did not like to speak. Then she realized that moving to a new country probably wasn't the easiest thing to do. There were hundreds of unfamiliar and unusual things to learn - all at the same time. "There're a lot of new things to learn, huh?" said Kate. Nadia nodded rapidly. In a quiet voice she replied, "Many things people say, I do not understand. I have been speaking English and Romanian all my life, but I do not know what some children are saying. For example, yesterday a boy asked if I could help him find the USB port on a thin black box he was carrying. Isn't a port a place for ships? It made no sense to me." "Don't worry." said Kate. "You'll figure everything out in time. You see, that thin black box was a computer. A USB port is a place where you can connect other machines to a computer." Nadia and Kate were quiet after that. They took notes while the teacher gave a maths lesson. To Kate's surprise, Nadia put up her hand and offered to answer the questions at the blackboard. Nadia handled every question the teacher gave her. Some of the questions were really difficult, and no one understood what was going on except Nadia and the teacher. When the teacher said that Nadia answered everything correctly, the whole class clapped their hands. Nadia was smiling when she sat back down next to Kate. "Some things," she said in a normal voice, "are the same all over the world." Question: At the beginning of Nadia's first day at school, she was _ . Yes or no, is the answer "shy."?
