Article: On October 23, 2011, David Pologruto, a high school physics teacher, wasstabbed by his smart student Jason Haffizulla. Jason got straight A's and was determined to study medicine at Harvard, yet this was his downfall. His physics teacher gave Jason a B, a mark Jason believed wouldundermine his entrance to Harvard. After receiving his B, Jason took a butcher knife to school and stabbed his physics teacher. How can someone as smart as Jason do something so dumb? Studies show there is little or no correlation between IQ and emotional intelligence. During my early university years, I regarded myself as an intelligent guy. I got good marks in mathematics, physics, and other subjects. I thought such skills would surely give me a bright future. After one year of study with decent marks, I began to see two major classes of students. The first category of students turned up to few lectures, partied every weekend, enjoyed a great social life, and did minimal work to pass courses. The second category of students were intelligent and hard workers who got good grades and were very focused on their studies. Surely would these intelligent and hard-working students find the great jobs before the other lazier class of students? Not so. Students are often shocked upon graduation that their qualifications are not as important as they once thought. Graduates enter the workforce only to realize that co-workers hate them and less intelligent people are the ones receiving promotions. Educational skills are useless in some industries when interpersonal skills are absent. You can have great ideas, theories, and solve complex problems, but if you cannot effectively communicate in a persuasive and exciting manner by relating to your fellow humans, you will face an uphill battle in whatever challenges you encounter. It's not that people dislike you because of your intelligence; it's that people dislike you because you're rude and not understanding. The intelligent person with poor communication skills is insensitive or unaware of others' emotions.
Answer: he got a worse mark than usual
Jason Haffizulla stabbed his physics teacher because _ .

Article: In the Caucasus region of Russia, nearly 50 out of every 100,000 people live to celebrate their 100th birthday, and many don't stop at 100! By comparison, in America only 3 people in 100,000 reach 100. But these Russian old people aren't alone. The Pakistanis, who live high in the Himalaya Mountains, and the Ecuadorans of the Andes Mountains seem to share the secret of long life, too. These people remain healthy in body and spirit despite the passage of time. While many older persons in industrial societies become weak and ill in their 60s and 70s, some Caucasians aged 100 to 140, work in the fields beside their great-great-grandchildren. Even the idea of aging is foreign to them. When asked "at what age does youth end?"most of these old people had no answer. Several replied, "Well, perhaps at age 80." What accounts for this ability to survive to such old age, and to survive so well?First of all, hard physical work is a way of life for all of these long-lived people. They begin their long days of physical labor as children and never seem to stop. For example, Mr . Rustam Mamedov is 142 years of age. His wife is 116 years old. They have been married for 90 years. Mr. Mamedov has no intention of retiring from his life as a farmer. "Why?What else would I do?"he asks. All these people get healthful rewards from the environment in which they work. They all come from mountainous regions. They live and work at elevations of 1,660 to 1,000 meters above sea level. The air has less oxygen and is pollution-free. This reduced-oxygen environment makes the heart and blood vessel system stronger. Another factor that may contribute to the good health of these people is their isolation. To a great extent, they are separated from the pressures and worries of industrial society. Inherited factors also play some role. Most of the longest-lived people had parents and grandparents who also reached very old ages. Good family genes may, therefore, be one factor in living longer.
Answer: are still working in the fields
The example of Mr. and Mrs. Mamedov implies that some Caucasians aged 100 to 140 _ .

Article: Popular breakfast foods in the United States, as in many other countries around the world, include coffee, milk , juice, eggs, and bread. Some other breakfast items served in the United States are thought by many to be traditionally American. However, they actually come from other cultures. A very popular breakfast food in America is the pancake--- a thin , flat cake made out of flour and often served with maple syrup. The idea of the pancake is very old. In fact, pancakes were made long ago in ancient China. Bagels, a round thick bread with a hole in the middle , are also popular for breakfast in America. Polish people in the late 1600s came up with the idea for the first bagels and this new kind of bread soon took off across Eastern Europe. In the late 1800s, thousands of Jews from Eastern Europe travelled to the United States and brought the recipe for bagels with them. Today, New York bagels are said to be the best in the world. Many people have them with cream for breakfast on the go. Doughnuts (usually spelled "donut" in the United States) came from France. They were served to American soldiers in France in the World War I. After the war, American soldiers asked cooks in the United States to make doughnuts for them. Now , served with coffee, they are a very popular breakfast food across the United States.
