Read the following article and select the best answer. Article: A towering South American plant that is believed to kill animals with its spikes and use their rotting bodies as fertilizer is about to bloom in England. A rare Puya chilensis was planted at a greenhouse in Surrey, a county in the southeast of England about 15 years ago. However, despite its frightening description, the tall, spiked plant is considered a threatened species. The Royal Horticultural Society has been feeding the plant a diet of liquid fertilizer. "In its natural habitat in the Andes it uses its razor sharp spikes to _ and trap sheep and other animals, which slowly starve to death and rot at the base of the plant, providing it with a bag of fertilizer," reads a description on the RHS website, which adds that the plant gives off a "gruesome scent." But does the plant actually trap and eat sheep? Other sources have simply said it is "believed" that the plant traps small animals with its spikes. After the animals die of starvation, the plant is "believed" to then use their rotting bodies as fertilizer to feed itself. "I'm really pleased that we've finally persuaded our Puya chilensis into producing flower," horticulturalist Cara Smith said in a press release on the RHS site. Regardless of whether it actually traps sheep, the plant does have sharp spikes that can grow up to 12 feet high and 5 feet wide. However, it's not all death and danger for this plant. Its flowery blooms reportedly provide nectar for bees and birds. The Puya chilensis blooms annually in its native land of Chile, but this is the first time it has done so after more than a decade of cultivation efforts from the RHS. "We keep it well fed with liquid fertilizer as feeding it on its natural diet might prove a bit problematic," Smith said. "It's growing in the dry section of our glasshouse with its deadly spines well out of reach of both children and sheep alike." Question: From the passage we learn that in England the Puya chilensis _ . - feeds on man-made liquid fertilizer - often kills sheep and other animals - has once bloomed 15 years before - uses animals' rotting bodies as fertilizer
feeds on man-made liquid fertilizer

Read the following article and select the best answer. Article: When her five daughters were young, Helene An always told them that there was strength in unity . To show this, she held up one chopstick, representing oneperson. Then she easily broke it into two pieces. Next, she tied several chopsticks together, representing a family. She showed the girls it was hard to break the tied chopsticks. This lesson about family unity stayed with the daughters as they grew up. Helene An and her family own a large restaurant business in California. However, when Helene and her husband Danny left their home in Vietnam in 1975, they didn't have much money. They moved their family to San Francisco. There they joined Danny's mother, Diana, who owned a small Italian sandwich shop. Soon afterwards, Helene and Diana changed the sandwich shop into a small Vietnamese restaurant. The five daughters helped in the restaurant when they were young. However, Helene did not want her daughters to always work in the family business because she thought it was too hard. Eventually the girls all graduated from college and went away to work for themselves, but one by one, the daughters returned to work in the family business. They opened new restaurants in San Francisco and Los Angeles. Even though family members sometimes disagreed with each other, they worked together to make the business successful. Daughter Elisabeth explains, "Our mother taught us that to succeed we must have unity, and to have unity we must have peace. Without the strength of the family, there is no business." Their expanding business became a large corporation in 1996, with three generations of Ans working together. Now the Ans' corporation makes more than $20 million each year. Although they began with a small restaurant, they had big dreams, and they worked together. Now they are a big success. Question: Helene tied several chopsticks together to show _ . - the strength of family unity - the difficulty of growing up - the advantage of chopsticks - the best way of giving a lesson

Read the following article and select the best answer. Article: For twenty years, I saved all my college course notes and textbooks: that's a lot of paper. Worse, it's not easy to carry them around -- and trust me, they aren't light -- on at least seven moves. Yet I never once looked at them. They sat in our basement, covered in a thick layer of dust. If books and papers could wonder, they'd wonder why they were still under our stairs after all those years. When would the Big Day come? Well, the Big Day eventually did arrive; only it was different than expected. My wife, always more accepting changes than I am, finally talked me into clearing out the entire mess. The pain I experienced was also unexpected. What hurt me was to come across those terrible papers I'd written, which reminded me of my poor study habits, and an embarrassing lack of comprehension. It was great to get rid of them. But it was also a clearing of personal history. At first, I struggled with this. The truth was in the record that my books, my notes, and my papers were primary source materials, documenting an important time in my life. To clear them out was to clear out the truth. What I've learned since taking this leap is that the process is more important than the truth. I feel as if much of my real education during my college years isn't in the documents but now in me. So I am glad to free myself of this physical burden. And what's better is that I don't need to look back to those painful moments. They belong to the past. You might want to consider doing something similar, either under the stairs of your basement or in your mind. What is the personal rubbish piling in your life? Clear _ out and make your life awesome. Question: What would be the best title for the passage? - Let It Go - Sort It Out - Give up the Past - Forget the History
Let It Go
