Answer the following question: I'm taking a test and have to guess the right answer to the question after the article. Article: My sister and I grew up in a little village in England. Our father was a struggling lawyer, but I always knew he was special. He never criticized us, but used praise to bring out our best. He'd say, "If you pour water on flowers, they flourish . If you don't give them water, they die." I remember as a child I said something unkind about somebody, and my father said, "Any time you say something unpleasant about somebody else, it's a reflection of you." He explained that if I looked for the best in people, I would get the best in return. From then on I've always tried to follow the principle in my life and later in running my company. Dad's also always very understanding. At 15, I started a magazine. It was taking up a great deal of my time, and the headmaster of my school gave me a choice: stay in school or leave to work on my magazine. I decided to leave, and Dad tried to _ the decision at first, as any good father would. When he realized I had made up my mind, he said, "Richard, when I was 23, my dad persuaded me to go into law. And I've always regretted it. I wanted to be a biologist, but I didn't pursue my dream. You know what you want. Go fulfill it." As it turned out, my little publication went on to become Student, a national magazine in the U.K.. My wife and I have two children, and I'd like to think we are bringing them up in the same way Dad raised me. Question: The author left school at 15 mainly because _ . Options: A: the school forced him to B: he had to work for money C: his father understood him D: He had a dream to fulfill
Answer:
D
