Article: While others look away from trouble, this lady digs in and gets to work. Gretchen Buchenholz, the native New Yorker and mother of six, has worked on behalf of needy and margin1alized families for years in the city. She does everything from buy groceries for homeless families to start schools for children. In 1974 she founded Merricat's Castle, a nursery school that opened its doors to kids of all racial and economic backgrounds, the able-bodied as well as those with disabilities or terminal illnesses. She founded the Association to Benefit Children (ABC), the nonprofit group, some 20 years ago. The story of how she started ABC is pretty amazing. In 1984 she was on her way to a government office to get a day-care permit when, by accident, she entered a room where homeless families were waiting to be placed in a " welfare hotel." She saw three bare cribs with babies lying in them. The children wore no diapers (their parents couldn't afford them), and the room was filthy . After talking to the parents and learning that they and their children were hungry, Gretchen marched out and bought bread, peanut butter, apple juice and diapers. Then she started making phone calls. She dialed the American Red Cross, City Hall and The New York Times. Gretchen has made many people see that we need to recognize these children are not different from our own, and we need to join in and help. Too often, people look away from suffering. But she sets us an example that we should gain strength to do something about it.
Question: She went to the government office _ .
Options: (A) to help those homeless people in the room (B) to apply for a permit for ABC (C) to call on the government to help those homeless children (D) to get permission to look after babies during the day

Article: I have nothing to say about whether or not "A Day Without Immigrants" had a positive or negative effect on the question of how the federal government should deal with the huge population of undocumented illegal immigrants in this country. I'll leave that question to others. Regardless of how you feel about the event, one conclusion is obvious. Using the theme of" A Day Without" as a way to focus national attention on a particular subject is a great idea, and could serve as a method for increasing public awareness about other issues that affect daily life in America. Here are my top three examples: "A Day Without Speeding." How hard could this be? If all drivers would strictly obey every posted speed limit on highways, downtown, on neighborhood streets, and in parking lots for one 24-hour cycle, the benefits would be huge. "A Day Without Losing Your Temper." A higher degree of difficulty here, and I know that from personal experience. When something goes wrong at home or on the job, there may be brief satisfaction in yelling or kicking the furniture, but erupting with anger usually doesn't do anything to solve the problem, and in many cases it makes the situation more unpleasant. "A Day Without Having All The Answers." I would like to get a break from hearing anyone speak the phrase, "Here's what you're doing wrong." Right now the US is jampacked with citizens who believe they can point out the cause of every single problem in existence and then solve it on the spot. I believe they need to be quiet sometimes and use their ears instead of their voices. I wonder how would average Americans react to such a collective pause? Would it be a day of angry protests, or joyful celebrations?
Question: According to the writer, losing one's temper is _ .
Options: (A) personal (B) satisfying (C) pointless (D) unpleasant
C
