Read the following article and select the best answer. Article: A single night of taking the drug Ecstasy can cause serious brain damage and speed up the start of Parkinson's disease , scientists say. Just two or three Ecstasy tablets can permanently destroy brain cells that affect movement and reasoning, according to American research that links the drug to Parkinson's for the first time. A study by a team at Johns Hopkins University in Baltimore, Maryland, involving squirrel monkeys and baboons found that both species suffered permanent damage to key cells, which are lost in Parkinson's, after receiving three low doses of Ecstasy at three-hour periods. The study is particularly important because baboons are one of the best animal models for the human brain. George Ricaurte, who led the research, said that the widespread abuse of drug might have caused severe damage. "The most troubling result is that young adults using Ecstasy may be increasing their risk of developing Parkinsonism as they get older." Alan Leshner, a former director of the US National Institute on Drug Abuse, said, "This study emphasizes the multi-aspect damage that Ecstasy causes to users. We've long known that repeated use damages brain cells. But this study shows that even very occasional use can have long-lasting effects on many different brain systems. It sends an important message to young people: don't experiment with your own brain." Janet Betts, a mother whose teenage daughter Leah died after a single Ecstasy tablet in 1995, said, "This comes as no surprise. But people can't see the effects at first, and they say it won't happen to them. We'll see the symptoms later, just as we have with smoking." Question: We know from the passage that a low dose of Ecstasy _ . - can permanently destroy one's brain cells - can cause serious brain damage occasionally - will result in immediate symptoms - may bring on Parkinson's at once
**Answer**
can permanently destroy one's brain cells

Read the following article and select the best answer. Article: One day when I was 12, my mother gave me an order: I was to walk to the public library, and borrow at least one book for the summer. This was one more weapon for her to defeat my strange problem -- inability to read. In the library, I found my way into the "Children's Room." I sat down on the floor and pulled a few books off the shelf at random. The cover of a book caught my eye. It presented a picture of a beagle. I had recently had a beagle, the first and only animal companion I ever had as a child. He was my secret sharer, but one morning, he was gone, given away to someone who had the space and the money to care for him. I never forgot my beagle. There on the book's cover was a beagle which looked identical to my dog. I ran my fingers over the picture of the dog on the cover. My eyes ran across the title, Amos, the Beagle with a Plan. Unknowingly, I had read the title. Without opening the book, I borrowed it from the library for the summer. Under the shade of a bush, I started to read about Amos. I read very, very slowly with difficulty. Though pages were turned slowly, I got the main idea of the story about a dog who, like mine, had been separated from his family and who finally found his way back home. That dog was my dog, and I was the little boy in the book. At the end of the story, my mind continued the final scene of reunion, on and on, until my own lost dog and I were, in my mind, running together. My mother's call returned me to the real world. I suddenly realized something: I had read a book, and I had loved reading that book. Everyone knew I could not read. But I had read it. Books could be incredibly wonderful and I was going to read them. I never told my mother about my "miraculous" experience that summer, but she saw a slow but remarkable improvement in my classroom performance during the next year. And years later, she was proud that her son had read thousands of books, was awarded a PhD in literature, and authored his own books, articles, poetry and fiction. The power of the words has held. Question: Which one could be the best title of the passage? - The Charm of a Book - Mum's Strict Order - Reunion with My Beagle - My Passion for Reading
**Answer**
The Charm of a Book
