Question: Read the following article and select the best answer. Article: None of our early ancestors could digest milk as adults because their bodies never had to -milk drinking simply wasn't an option.As people began to extract milk from animals, though, some people developed the ability to keep drinking it throughout their lives. Scientists mow know of a milk-related mutation in our genes--the chemical instructions for life that we carry in almost every cell in our bodies.People who have a mutated form of one particular gene can drink milk just fine.People without the mutation tend to get sick from milk. To figure out where, and possibly why, milk drinking started, some scientists have been looking at who has the milk-digesting mutation to day Pattems are striking. Most adults in Northern and Central Europe are able to digest milk--and they do.Cheese, butter and other dairy products are popular in countries such as Sweden, Denmark, Germany and England.Because European settlers dominated North America, most people here can handle milk just fine, as well.That may explain why ice cream is such a popular dessert in the United States. In much of Africa, Asia and South America, on the other hand, people tend to avoid dairy products because they lead to diarrhea and other stomach problems.(That's why you won't typically find cheese on the menu at a Chinese, Japanese or Ethiopian restaurant.) Native Americans are also unable to digest milk. Based on these genetic patterns, scientists have long thought that milk drinking started in Northern Europe, where dairy is an institution and the milk-digesting mutation is everywhere. A recent study painted a different picture.With a computer model, Thomas and colleagues looked at the spread of the milk-drinking mutation, farming and other related factors.Working backward, the scientists concluded that the first milk-drinkers lived in Central Europe around what's now Hungary about 7500 years ago.The practice didn't start farther north, as scientists had thought before. Question: The main focus of the scientists' research was _ . - mutation of human genes - development of the human stomach - why milk drinking started - where milk drinking first started
Answer: where milk drinking first started

Question: Read the following article and select the best answer. Article: I had a very good teacher named Leon Sultan .I liked him very much.

When he called my name, he asked if I remembered him. Then I realised that he was the teacher who had taught me English when I was in primary school. Mr. Sultan was a very special teacher. Even though he was older and had been to college, but he was Still ready to learn from others. He would listen to your opinion carefully before expressing his opinion. I think what he taught me more than anything else is to have an open mind Another thing I couldn't forget was his teaching method -group work There were four members in the group. Each group had its own topic. Everyone in the group would play a certain role. One would keep the discussion moving, the other one would write down the thoughts of the group, another one would be responsible for gathering information, and another one would share everything the group had discovered with the rest of the class. This allowed us to become "experts" on one topic and teach the rest of our classmates. Now ,I have become a more open-minded boy. That is because of my two and a half years in Mr. Sultan's class. Question: What was strange about the author's schedule? - It was picked up by Mr. Sultan - It was taken away by Mr. Sultan. - It didn't show Mr. Sultan's name. - t didn't have the courses that he had chosen.
Answer: It didn't show Mr. Sultan's name.
