Article: To most of us,school means classes,teachers,schedules,grades,and tests.But for the children at Sudbury Valley School in Massachusetts,school is very different. Firstly,there are no lessons.All the children,aged between 4 and 19,do whatever they want.There are no teachers--only "staff members".The idea behind this is that you do not need to make children learn,because children want to learn anyway."You do not need to say to a three yearold,'Go explore your environment.'You can't stop them!" says Daniel Greenberg,a founder of the school."But if you make children do what you want all day,they will lose all taste for learning." At Sudbury Valley School,you will permit children to talk,read,paint,cook,work on computers,study French,play the piano,climb trees or just run around.Two boys spent three years just fishing! The other way that Sudbury Valley School is different is that the children can decide the rules.Every week,there is a school meeting where both children and staff have one vote each--even the fouryearolds.They decide the school rules,how to spend the school budget,and even which staff they want and do not want any more. When the school first opened in 1968,people said it would never work.But today,the school has 200 students,and 80%of its students go on to college. Even the two boys who went fishing all the time have successful careers today.One of them is a musician and the other is a computer scientist.
Question: What is the main topic of the article?
Options: (A) An unusual school. (B) Children's hobbies. (C) A school without rules. (D) Education in the US.

Article: We live in central Phoenix, near the canal . Every day I used to see a homeless old man and his scruffy little dog hanging out down there. I would tell my husband we should give him food for the little dog. It wouldn't have been a problem; we have our own "mini farm" of animals! But he would say "OK!" and then blow the idea off because of our business. Being in Phoenix, Arizona, you can just imagine how hot it gets here, but his winter was really chilly! I had just come from KFC with take-out food for dinner. As I was turning by the canal, the man and his dog were sitting right there all bundled up. Even the doggy had a coat on! Not even thinking about it, I pulled into the parking lot along the canal and piled up a plate of chicken with all the fixings for the man and his little buddy . I gave it to him with a soda and a bottle of water for the little dog. He said, "Thank you, sweetie. You are an angel." And there were tears welling up in his eyes! I told him he was so welcome, and then went home. When my husband dug into the KFC bag he asked, "Were you hungry, or what?" I told him what I did and he said, "Only you!" Then he told me I had done a good thing. A few weeks later, we were walking along the canal and found the man walking to me, with his little dog. He asked whether I would mind adopting the dog. With tears in eyes, he said it had gotten too hard for him to care for the dog. He added that he was planning on heading to Washington State but his dog wouldn't have been up to it, so he hoped to give it to me. "Only you! In this city, you are the only person I can believe in!" Now, every time I watch and pat the dog lying near the fireplace, I will remember the old man's words and wish him good luck.
Question: What did the author's husband feel when she told him what she had done?

Article: Personal money-management website Mint.com suggests recently that responsible parents should give their kids credit cards--possibly starting as young as middle school. The website says a credit card will help children master responsible spending habits and give parents the chance to teach them some valuable lessons. It's absolutely true that kids should learn about how a credit card works and how to use it responsibly. But the idea that they need a card of their own to practise this is questionable. Yes, credit cards are a teaching tool, but it's the time you spend educating them about money management that does the teaching, not the piece of plastic. Sit down with your child--here we are referring to teens and walk them through your credit card statements. Point out important things like the due date, late fee warning, and APR . If you have good credit, adding a child as an authorized user onto one of your credit cards also provides teachable moments. Allow kids to use the card to make specific purchases and require their participation in payment. Since the card is still in your name, you can take them off it at any point and cut off their access if they're not able to handle the responsibility. Another option is to set them up with an account at a local bank that offers free use of a debit card . Unlike credit card, the debit card has no overdraft function. Children can only use the card to pay for things and the money is taken directly from their bank account. If the account is empty, the worst that will happen is the card being declined at a cash register.
Question: Why does Mint.com advise parents to give middle school kids credit cards?
Options: (A) To leave their kids financially independent. (B) To help their kids form good spending habits. (C) To teach their kids' how to save pocket money. (D) To strengthen the relationship with their kids.
