Input: Consider Input: Article: Millions of people will be able to track each and every move by friends and family through their mobile phones,thanks to a new feature launched by Google yesterday. The new system named "Latitude" uses a map to show exactly where a loved one is at any time, sometimes discovering their location to a few meters.Worried parents will be able to check up on where their children have got to after school, friends can meet for a quick drink if they see they are nearby and wives will be able to see if their husbands really are working late at the office. The feature was made available immediately on millions of mobile phones that can access the web,such as the BlackBerry.Within weeks Google hopes to launch a new one that wilt also work on computers as well. "Once you've shared your location,you can hide it from all of your friends at once,or you can turn off Google Latitude completely at any time." said a Google spokesman."You can adjust your privacy settings in Latitude so that you share as much or as little about your location as you want,with whom you want." Google said that the company had tested the product with thousands of people to make sure that it was safe for the customers,but experts were not so sure.Simon Davies,director of Privacy International,said Latitude would open up a "privacy minefield ". "It's about the little white lies.You might be avoiding going to work, and now your boss might be able to see that you're at Twickenham instead of at home."said Ian Angell, an information expert at the London School of Economics."You've already got mobile phone technology where husbands and wives track each other in secret.Now Google is so widely used that it will only worsen the situation."

Input: Consider Input: Article: Many people say dolphins are very intelligent. They seem to be able think, understand, and learn things quickly. But they are smart like humans or more like cats or dogs? Dolphins use their brains differently from people. But scientists say dolphin intelligence and human intelligence are alike in some ways. How? FACT 1: Talk to Me Like humans, every dolphin has its own "name". The name is a special whistle . Each dolphin chooses a specific whistle for itself, usually by its first birthday. Actually, scientists think dolphins, like people, "talk" to each other about a lot of things, such as their age, their feelings, or finding food. And, like humans dolphins use a system of sounds and body language to communicate. But understanding their conversations is not easy for humans. No one "speaks dolphin" yet, but some scientists are trying to learn. FACT 2: Let's Play Dolphins are also social animals. They live in groups called pods, and they often join others from different pods to play games and have fun ---just like people. In fact, playing together is something only intelligent animals do. FACT 3: Fishermen's Helpers Dolphins and humans are similar in another way: both make plans to get something they want. In the sea of southern Brazil, for example, dolphins use a interesting strategy to get food. When fish are near a boat, dolphins signal to the fishermen to put their nets in the water. Using this method, the men can catch a lot of fish. What is the advantage for the dolphins? Why do they assist the men? The dolphins get to eat some of the fish.
Question: What is the text mainly about?
Options: (A) The comparison between dolphins and humans. (B) The relationship between dolphins and humans. (C) Different types of dolphins. (D) The habitual behavior of dolphins.

Output: A

Input: Consider Input: Article: Some American high schools are for students with special interests, like science or the arts. New York City even has a program for those interested in the food service industry, called Food and Finance High School. New York also has what are called international high schools, or internationals, for immigrant students. They must be new learners of English who have been in the United States less than four years. The first school opened in nineteen eighty-five. The city will begin the new term next month with ten. New York works with a nonprofit organization, the Internationals Network for Public Schools. Support from the Bill and Melinda Gates Foundation has helped the network expand. The network says the graduation rate was seventy percent last year in the four New York schools open long enough to have graduating classes. That, compared with twenty-three percent for English language learners in all of the city schools. Over all, New York officials recently reported that the city's four-year graduation rate, reached fifty-two percent last year. At the same time, they reported that the city's dropout rate fell below fifteen percent. The Internationals Network says its schools have an average dropout rate of just five percent. Claire Sylvan is the executive director of the group. She says students drop out mainly because their families need them to work or because parents arrange marriages for girls. The Internationals Network mainly helps find teachers and trains them in the teaching method of the internationals. Claire Sylvan says the teaching approach is to have students use their different strengths to help each other. They work in small groups, but she says they are not grouped by ability. She says the students discuss issues, then produce a product like a paper, a play, a poster or a report. They learn English as they work.
