Write a multi-choice question for the following article, with the given choices and answer: Article: Hawaii is an important trading center and about six million tourists visit there every year. With all that traffic in and out, exotic species have plenty of opportunities to reach the islands. According to biologists, exotic species are the number one threat to the state' s economy, environment, and way of life. The question in Hawaii is, can the invaders be stopped? Quarantines are one way to do this. Quarantine is the process of isolating animals or products. In Hawaii, pet dogs and cats coming into the state remain in a special holding facility for four months to make sure they don' t have rabies( ) Many agricultural products are also quarantined to see if they are carrying insect pests or plant diseases. Inspection is a second way to stop biological invaders. At airports, borders, and shipping ports, inspectors examine passengers and their baggage to see if they are carrying exotic species. The inspectors also destroy fruits, vegetables, or other goods that might be carrying harmful pests or diseases. Specially trained dogs also smell goods in the ship for exotic species. What if an exotic species slips by inspectors? Then efforts are made to control the invader. In Hawaii,government agencies control invaders by setting livetraps around wildlife shelters and other places. At Haleakala National Park employees have built miles of fences to keep out exotic pigs and goats. For years these animals ate and walked over native rain forest plants, hut the fences have helped reverse( )this damage. Now native plants grow in places that were bare rock only a short time ago. In some cases biological control helps to solve the exotic species problems. It is the science of controlling one invader with another. In the early 1900s, several exotic predators were imported to Hawaii to eat a harmful exotic pest called the sugarcane leafhopper. The insect was destroying 70,000 tons of sugar a year ,but the predators brought it under control. The efforts of these scientists and other people are vitally important. In Hawaii...

Write a multi-choice question for the following article, with the given choices and answer: Article: I never knew how amazing it would feel to help a family 4,560 miles away from my home. I never knew how great an effect I could have on that single family. From the moment I walked into French class, I knew almost instantly that I belonged there. My teacher, Madame Weiser, is a kind and caring woman, and is the person who started the interest within me to help a family abroad, no matter how many miles apart. Back in 2011, my teacher traveled as a tourist to Maxi, a country settled in West Africa with a large French-speaking population. She didn't expect to adopt an entire family, but fate had other plans. Madame met a nice man named Monsieur Diarra, a driver who had shown her the way through the dry lands of Mali. Mali is now a war-torn country and unsafe for tourists to visit, leaving little work for taxi drivers. Madame Weiser realized how Monsieur Driarra's family struggled on a daily basis, for he had a wife and four children to support as well as their grandmother, so she made a final decision to send the family as much money as she could raise every month. Now, three years later, Madame Weiser has still kept up her fund, collecting money from family and friends as well as students to support _ . It has become more than just my teacher donating to her adopted family abroad. As president of French Club at my high school and a French Honor Society member, I decided that our club should work to raise money for the family in need. By washing cars, we raised over $1,000.
