Q: Read the following article and select the best answer. Article: Americans have developed an olive oil habit. Out to dinner recently, I saw a man dipping his white bread in olive oil and then pouring it all over his salad, saying, "Wow, this is so good for me!" But is olive oil the healthiest fat? No, it's not. You might ask, doesn't it lower cholesterol ? Well, only when you substitute olive oil in equivalent amounts for butter or oils that are higher in saturated fat. Olive oil doesn't lower cholesterol; it just doesn't raise it as much. You may be better off with canola oil. The 1999 Lyon Diet Heart Study found that a Mediterranean diet significantly reduced heart attacks and premature deaths. Many people attributed this to eating a lot of olive oil. But it was increased consumption of canola oil that accounted for these improvements. Also, study participants ate more whole-grain bread, vegetables, fish and fruit, and less meat. Butter and cream were replaced with man-made butter made from canola oil, which has more healthy omega-3 fatty acids than olive oil does. Another study found that olive oil reduced blood flow by 31%. Canola oil and fish oil don't. (You want to increase blood flow to all body parts.) I like the taste of olive oil, and I use it sometimes. It's a healthier fat than many others, but it's not nearly as healthy as canola oil -- or fish oil and flaxseed oil, for that matter, which also have lots of omega-3s. And a tablespoon of any oil has 126 calories. Think about that before you pour it on. Question: The author may advise people _ . - to choose canola oil instead of olive oil - to think over before choosing new products - to keep on eating olive oil to keep healthy - to consult the researchers before accepting a trend
A: to choose canola oil instead of olive oil

Q: Read the following article and select the best answer. Article: I was shopping in the supermarket when I heard a young voice. "Mom, come here! There's a lady here my size!" The mother rushed to her son; then she turned to me to apologize. I smiled and told her, "It's okay." Then talked to the boy, "Hi, I'm Darry Kramer. How are you?" He studied me from head to toe, and asked, "Are you a little mommy?" "Yes, I have a son," I answered. "Why are you so little?" he asked. "It's the way I was born," I said. "Some people are little. Some are tall. I'm just not going to grow any bigger." After I answered his other questions, I shook the boy's hand and left. My life as a little person is filled with stories like that. I enjoy talking to children and explaining why I look different from their parents. It takes only one glance to see my uniqueness. I stand three feet nine inches tall. I was born an achondroplasia dwarf . Despite this, I did all the things other kids did when I was growing up. I didn't realize how short I was until I started school. Some kids joked on me, calling me names. Then I knew. I began to hate the first day of school each year. New students would always stare at me as I struggled to climb the school bus stairs. But I learned to smile and accept the fact that I was going to be noticed my whole life. I decided to make my uniqueness an advantage rather than a disadvantage. What I lacked in height, I made up for in personality. I'm 47 now, and the stares have not _ as I've grown older. People are amazed when they see me driving. I try to keep a good attitude. When people are rude, I remind myself, "Look what else I have--a great family, nice friends." It's the children's questions that make my life special. I enjoy answering their questions. My hope is that I will encourage them to accept their peers (a person of the same age, class, position, etc.), whatever size and shape they come in, and treat them with respect. Question: Why did the mother apologize to the author? - Because the boy studied the author from head to toe. - Because the boy laughed at the author. - Because they boy said the author was shorter than him. - Because the mother thought the boy's words had hurt the author.
A: Because the mother thought the boy's words had hurt the author.

Question: From the passage we can infer that America won its independence in _ . - 1786 - 1800 - 1842 - 1776
