Input: Consider Input: Article: It's nine o'clock on a Tuesday night.You are trying to finish your maths assignment. You have only two problems left to go.Almost done!You are looking forward to a nice snack and your favorite TV show.You read the next problem and groan.You don,t have a clue how to do it .You may check your notes from class .Or you may try reading your text-book .But the problem might as well be written in a foreign language. Does this sound familiar? Most people who have taken any kind of maths class have had this experience.What do you do when you get stuck? Perhaps you call a friend.Or you ask a family member for help.But what if it's late at night? Years ago there were very few ways to get help if you were stuck on a maths problem. Maths is different from other school subjects.You often cannot find what to do in a book.A dictionary or even an encyclopedia probably won't help you.You need someone to show you the steps.Learning most kinds of maths is something like learning to play a musical instrument.You need a coach to show you what to do. In many areas there are homework telephone lines.These hot lines have volunteers.They can help you do homework in all subjects.A maths volunteer can explain the steps in a maths problem that has you stumped* Today you can also get help on the Internet.There are several homework help programs and Web pages .In some,you leave your question on a message board.Or you write it in an e-mail note.In other maths-help programs there are live volunteer teachers.You can wait for a real maths teacher to help you do the problem.

Input: Consider Input: Article: In the new book The Education of Millionaires,Michael Ellsberg suggests that although"there are many wonderful things you can learn in college,"few of them are applied to real life .So Ellsberg has written the book to tell"the capabilities and attitudes that will get you improved outside the classroom." I welcome the kind of debate about the value of higher education.It is necessary to remember, however,that Ellsberg also tells how important it is to make money.He mentions a number of college dropoutssuch as Bill Gates and Michael Dellto show how successful they have become without the benefit of a college degree.While Ellsberg stresses the achievements of dropouts,he includes degree holders who have become wealthy and famous.For example,of the current Fortune 500 CEOs,some 99%have a college degree.Similarly,of the Forbes 400 richest people in America,81%hold postseconda.ry degrees. But in the discussion,what is forgotten about the value is that the purpose of education is not simply to enable one to earn a living but to prepare one for living over the course of life .What is also left out of the debate about higher education is that its purpose is not just to provide a pathway covered with gold for the nation's elites .If we have the discussion that way,we may look down upon the people who devote themselves to other ordinary jobs that form the basic structures of our society,Though these individuals may not be reaching for the kind of stars that Michael Ellsberg and others would have them grasp,most are doing something even more important:they are involved in the useful tasks of good citizens and contributing to the common welfare,including providing for their families.
Question: In the book The Education of Millionaires,Michael Ellsberg _ .
Options: (A) approves of the value of education (B) explains the reasons for dropping out (C) tells the way of getting out of college (D) discusses the practical value of college degrees

Output: D

Input: Consider Input: Article: It was Thanksgiving morning and in the crowded kitchen of my small home I was busy preparing the traditional Thanksgiving turkey when the doorbell rang. I opened the front door and saw two small children in rags huddling together. "Any old papers, lady?" asked one of them. I was busy. I wanted to say "no" until I looked down at their feet. They were wearing thin little sandals, wet with heavy snow. "Come in and I'll make you a cup of hot cocoa." They walked over and sat down at the table. Their wet sandals left marks upon the floor. I served them cocoa and bread with jam to fight against the cold outside. Then I went back to the kitchen and started again on my household budget. The silence in the front room struck me. I looked in. The girl held the empty cup in her hands, looking at it. The boy asked in a flat voice, "Lady, are you rich?" I looked at my shabby slipcovers. The girl put her cup back in its saucer carefully and said, "Your cups match your saucers." Her voice was hungry with a need that no amount of food could supply. They left after that, holding their bundles of papers against the wind. They hadn't said "Thank you." They didn't need to. They had reminded me that I had so much for which to be grateful. Plain blue china cups and saucers were only worth five pence. But they matched. I tasted the potatoes and stirred the meat soup. Potatoes and brown meat soup, a roof over our heads, my man with a good steady job--these matched, too. I moved the chairs back from the fire and cleaned the living room. The muddy prints of small sandals were still wet upon my floor. Let them be for a while, I thought, just in case I should begin to forget how rich I am.
