Q: Read the following article and answer the question. Article: The World Health Organization has for the first time expressed "cautious optimism" that the growth in new Ebola cases in West Africa may be slowing down. Bruce Aylward, who is in charge of the WHO response to Ebola, said in Geneva that he was particularly encouraged by evidence of a downward trend in Liberia, one of the three worst-affected countries. The WHO's official total number of Ebola cases has reached 13,703 - a big jump from the10,141 cases it reported four days ago. But Dr Aylward said that was mainly the result of the data being updated with old cases, rather than new cases arising. "Do we feel confident that the response is now getting an upper hand on the virus? Yes, we are seeing a slowing rate of new cases, very definitely," Dr Aylward said. However, Dr Aylward also urged people not to celebrate pre-maturely over any apparent downturn in the epidemic . "I'm terrified that the information will be misunderstood and people will think Ebola is under control," he said. Any reduction in the battle against the virus might lead to "an oscillating pattern where the disease moves up and down". The improvement in Liberia seems to be due to a combination of more treatment facilities, better contact tracing and safer burial practices, together leading to fewer new infections from Ebola patients. In Sierra Leone the number of cases continues to increase in some areas. "We're still seeing this thing _ in parts of Sierra Leone," Dr Aylward said Tracing the progress of individual patients, the WHO estimates an overall death rate of 70 percent, though people who receive treatment in a well-equipped clinic are slightly less likely to die. The WHO plans to set up 56 Ebola clinics with 4,700 beds in West Africa. Of these 15 clinics with 1,050 beds are already operational and another 22 clinics are expected to open during November. Meanwhile, two former NATO secretaries-general and dozens of leading European politicians have urged the alliance to send troops, aircraft and ships to west Africa to help contain the... Question: Which of the following didn't contribute to the improvement in Liberia? Answer: | OPTIONS:
- better contact tracing
- more treatment facilities
- safer burial practices
- data updated with old cases
A: data updated with old cases

Q: Read the following article and answer the question. Article: "A child is dying---out of breath!" I had just begun my working day in the city, when those words came through the radio of the police car I was driving. I turned on the red lights and siren and drove off as fast as I could. "Just my luck!" I thought. I did not know this city well and my first call of the day was a life-and-death sudden happening, several kilometers away. I got to the house. A mother, filled with fear, handed me her baby, his face already blue. Was I too late? Dear me! I did what I had been taught to do in such a serious condition. A small thing flew out of the baby's mouth onto the floor. It was a button. Thanks heavens! The holes in it let a little air through. The doctor rushed into the room. He had with him an oxygen bag. The child began to cry at the top of his voice, turned red and started to look for his mother. He was angry but saved. Question: What did the writer mean when he said to himself "Just my luck!"? Answer: | OPTIONS:
- It was a good chance for him to practice what he had learned before
- He was happy to have such a serious matter on his working day
- He was not at all happy to have so serious a matter on his working day
- He had been long waiting for the day to come.
A: He was not at all happy to have so serious a matter on his working day

Q: Read the following article and answer the question. Article: Scientists who try to predict earthquakes have gotten some new helpers recently--animals. That's right, animals. Scientists have begun to understand what farmers have known for thousands of years. Animals often seem to know in advance that an earthquake is coming, and they show their fear by acting in strange ways. Before a Chinese quake in 1975, snakes awoke from their winter sleep early only to freeze to death in the cold air. Cows broke their halters and tried to escape. Chickens refused to enter their cage. All of this unusual behavior, as well as physical changes in the earth, warned Chinese scientists of the coming quake. They moved people away from the danger zone and saved thousands of lives. One task for scientists today is to learn exactly which types of animal behavior predict quakes. It's not an easy job. First of all not every animal reacts to the danger of an earthquake. Just before a California quake in 1977, for example, an Arabian horse became very nervous and tried to break out of his enclosure. The Australian horse next to him, however, remained perfectly calm. It's also difficult at times to tell the difference between normal animal restlessness and "earthquake nerves". A zoo keeper once called earthquake researchers to say that his cougar had been acting strangely. It turned out that the cat had an upset stomach. A second task for scientists is to find out exactly what kind of warnings the animals receive. They know that animals sense far more of the world than humans do. Many animals can see, hear, and smell things that people do not even notice. Some can sense tiny changes in air pressure, gravity, or the magnetism of Earth. This extra sense probably helps animals predict quakes. A good example of this occurred with a group of dogs. They were shut in an area that was being shaken by a series of tiny earthquakes. (Several small quakes often come before or after a large one.) Before each quake a low booming sound was heard. Each boom caused the dogs to bark wildly. Then the dogs began... Question: Which of the following is one of earthquake nerves according to the passage? Answer: | OPTIONS:
- An Arabian horse tried to escape from his enclosure.
- A cougar had an upset stomach unexpectedly.
- An Australian horse was perfectly calm.
- A cat acted very strangely in a zoo.
A: An Arabian horse tried to escape from his enclosure.
