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.

Article: Who doesn't love sitting beside a cosy fire on a cold winter's night ? Who doesn't love to watch flames curling up a chimney? Fire is one of man's greatest friends, but also one of his greatest enemies. Many big fires are caused by carelessness. A lighted cigarette thrown out of a car or train window or a broken bottle lying on dry grass can start a fire. Sometimes, though, a fire can start on its own. Wet hay can begin burning by itself. This is how it happens: the hay starts to rot and begins to give off heat which is trapped inside it. Finally, it bursts into flames. That's why farmers cut and store their hay when it's dry. Fires have destroyed whole cities. In the 17th century, a small fire which began in a baker's shop burnt down nearly every building in London. Moscow was set on fire during the war against Napoleon. This fire continued burning for seven days. And, of course, in 64 A.D. a fire burnt Rome. Even today, in spite of modern fire-fighting methods, fire causes millions of pounds' worthy of damage each year both in our cities and in the countryside. It has been wisely said that fire is a good servant but a bad master .
