Our planet is home to about seven billion people. Since the 1990s, population experts have predicted the number would grow to nine billion before it begins to slow down and possibly decrease. But a new report predicts the world's population is likely to increase to almost 11 billion by 2100. Based on the most modern statistical tools, the new report makes use of government records and considers expert predictions, including death rates, birthrates and international migration, or people moving across borders. The report says during the rest of this century, Africa's population will grow from about 3.5 billion to 5.1 billion over the next 85 years John is director of the United Nations Population Division. He says that in the past, researchers thought population growth in Africa would be similar to that of other areas. They expected slower growth rates as birth control use became more widespread. But he says those ideas were wrong. "The level of contraception use has continued to increase but slowly -- more slowly than expected, and birthrate therefore has been falling less rapidly than expected, and the population therefore continues to grow somewhat more rapidly than we expected.The new findings are based on a joint research project of the United Nations and the University of Washington. The researchers believe the population of Asia will reach five billion by 2050. That is up from the current 4.4 billion. And then begin to decline. The researchers also believe that North America, Europe, Latin America and the Caribbean area will have a total population of below one billion. John says the pressure of feeding the rising population is likely to be less than that might be expected. "The relatively good news is that the world has been winning the race between population growth and food production. If you look back historically over the last 50 years, certainly for the world as a whole and for many, most individual countries and regions, the increase in food production has outpaced the increase of population.||" What can be inferred from the passage? A) The world's population will increase constantly. B) The population of Asia will rise by 5 billion by 2050. C) John is optimistic about feeding the rising population. D) Population growth in Africa was much slower than expected.

Have you ever had a doctor write you a prescription for three laps around a local trail ? How about a prescription for sit-ups? These treatments may not be as typical as the drugs that are usually used to treat our problems, but maybe they should be: a new report shows that regular exercise can be just as effective as prescription drugs for patients with depression and anxiety. "Individuals who exercise report fewer symptoms of anxiety and depression, and lower levels of stress and anger, " said the paper's co-author, Jasper Smith, director of the Anxiety Research and Treatment Program at Southern Methodist University. " Exercise may help patients with depression re-establish positive behaviors. For patients with anxiety disorders, exercise reduces their fears of fear and related bodily sensations such as a racing heart and rapid breathing." In a separate study, published in Physical Therapy journal, scientists studied 161 women who' d recently given birth to babies, and decided them into two groups. New mothers tend to develop post-partum depression , and the scientists wanted to find out whether exercise could prevent such problems. One group of women was given specialized exercises as part of an eight-week parenting education program, while the other was given only written education. The physical element seemed to do the trick; the researchers report that the number of women identified as "at risk" for post-partum depression was reduced by half in the exercising group. Another recent study shows that even when a patient has a chronic illness like cancer or a heart condition, regular exercise can dramatically increase wellbeing by reducing anxiety. Researchers from University of Georgia analyzed 40 clinical trials involving almost 3,000 patients, and found that the patients who reported exercising regularly had a 20% reduction in symptoms of anxiety compared to those who didn't exercise. As a result, they were more likely to follow their recommended treatment plan. Of course, there are still some... Why does the writer mention another two studies? A) To compare the two studies to find their similarities. B) To prove the theory: regular exercise can reduce people's depression and anxiety. C) To compare Jasper Smith's study with the two ones. D) To help those suffering from depression and anxiety get rid of them.

Q: I made a pledge to myself on the way down to the vacation beach cottage. For two weeks I would try to be a loving husband and father. The idea had come to me as I listened to a talk on my car radio. The speaker was quoting a Biblical passage about husbands being thoughtful of their wives. Then he went on to say, "Love is an act of will. A person can choose to love." To myself, I had to admit that I had been a selfish husband. Well, for two weeks that would change. And it did. Right from the moment I kissed Evelyn at the door and said, "That new yellow sweater looks great on you." "Oh, Tom, you noticed," she said, surprised and pleased. Maybe a little puzzled. After the long drive, I wanted to sit and read. Evelyn suggested a walk on the beach. I started to refuse, but then I thought, "Evelyn's been alone here with kids all week and now she wants to be alone with me." We walked on the beach while the children flew the kites. So it went. Two weeks of not calling the Wall Street firm where I am a director; a visit to the shell museum though I usually hate museums. Relaxed and happy, that's how the whole vacation passed. I made a new pledge to keep on remembering to choose love. There was _ that went wrong with my experiment, however. Evelyn and I still laugh about it today. On the last night at our cottage, preparing for bed, Evelyn stared at me with the saddest expression. "What's the matter?" I asked her. "Tom, " she said in a voice filled with sadness, "do you know something I don't?" "What do you mean?" "Well.....that checkup I had several weeks ago..... our doctor ..... did he tell you something about me? Tom, you've been so good to me..... am I dying ?" It took a moment for it all to sink in. Then I burst out laughing. "No, honey," I said, wrapping her in my arms. "You're not dying; I'm just start to live." The writer thought he was a _ husband in the past. A) lovely B) loyal C) strict D) selfish
A: D
*Question*
Q My daughter is a junior in high school and has been on an individualized education program since fourth grade. She plans to go to college and intends to finish with a master's degree. Her performance is fairly good, but test scores are very low. She has held many leadership and volunteer positions. We have been advised to have her write an essay about how her learning disability is a barrier that she has overcome. Will that help or hurt her chances for admission? --Deborah AFirst let me answer the question on low standardized test scores (ACT/ SAT). There are hundreds of colleges that are "test optional" which means students can choose not to release their test scores in the application process. Admission decisions at these colleges for students who do not submit their test scores are made based on other factors. A list of test optional colleges can be found atfairtest.org. It is important, however, to make sure that the college is the right fit academically regardless of the test optional policy. You also asked if your daughter should write about her disability and if this would hurt her chances of being admitted. Please know that colleges do not deny admission based on disability. "Disclosing" a learning disability in a personal statement within the college application can certainly help. By writing a personal statement, students can potentially demonstrate, for example, their understanding of the challenge they face. They might also demonstrate an improved grade trend in that subject area, and show interest in more complex courses in spite of this disability. More importantly, a student disclosure can show self-confidence, motivation and an understanding of the disability. --Ms. Kravis According to Ms. Kravis, what can Deborah do about her daughter's low test scores? A) Keep them secret B) Explain the reasons C) Stress other aspects D) Work hard to improve
