Article: The Ring of Fire covers 4,000 km around the edge of the Pacific Ocean.It includes the countries of Japan,Indonesia and the Philippines.More earthquakes and volcanoes occur in this area than anywhere else in the world.The name Ring of Fire refers to areas below the earth's surface.These areas move suddenly and often cause earthquakes and create volcanoes. Many areas of Asia,such as the Philippines,Japan,and Indonesia, sometime experience earthquakes and volcanoes.There are occasionally landslides ,mudslides,and tidal waves as a result.Fortunately, these natural disasters do not happen very often. Southern China is about 600 km away from the Ring of Fire.Sometimes, people in this region feel earthquakes too.The worst earthquake felt in southern China was in 1918 in Shantou.It measured 7.3 on the Richter scale.Any earthquake of 6 or more on the Richter scale is very dangerous to people. People in Hong Kong sometimes experience the effects of earthquakes and volcanoes.In September 1994,for example,the strongest earthquake to hit Hong Kong for 76 years shook buildings and scared thousands of residents.Frightened workers and families ran out of their offices and homes.The earthquake measured 6.5 on the Richter seal. It is difficult to predict when an earthquake will occur In countries within the Ring of Fire, buildings must be very strong because the effects of earthquakes on buildings are terrible. In June 1991, Mt Pinatubo in the Philippines erupted.Many people were killed and the area surrounding the volcano was badly damaged.Hot ash and liquid rock from the volcano forced people to leave the area.They only returned many months later.The ash spread over a large area.Even people in the Guangdong region of southern China saw ash in the air.
Question: Many Asian countries_.
Options: (A) are outside the Ring of Fire (B) never experience natural disasters (C) experience earthquakes only (D) experience earthquakes and volcanoes

Article: By 2050 there will have been an extra 2.5 billion people on earth. And what will they eat? To solve the problem, we should have to double our food production. We can also develop a diet of algae , insects and meat grown in laboratories. Algae can grow very quickly at sea, in polluted water and in places that would normally kill food crops. They are already eaten widely in Japan and China and they are eaten by almost everything from shrimps to blue whales. They can fix CO2 in the atmosphere and provide fats and sugars. Man-made meat looks like meat, feels like meat and it is meat, although it's never been from a living, breathing animal. Instead, it is grown from cells in big containers. Moreover, studies show that producing man-made meat will use far less water, energy and land. China has developed "green super rice", a series of rice types which produce more grain and have stronger ability to fight against floods, salty water, insects and disease. We used traditional plant breeding techniques to cross-breed more than 250 rice types. Green super rice, which is enough to feed an extra 100 million people, will be planted widely in the coming years. Insects like ants are not on most European menus but at least 1,400 kinds are eaten across Africa, Latin America and Asia. Now, with rising food prices and worldwide land shortages, such insects are getting more and more popular. Not only are many insects rich in protein , low in fat and high in Ca and Fe, but insect farms need little space. And they can grow well on paper, algae and industrial wastes.
Question: In order to exist in the future, people have to _ .
Options: (A) move to other planets (B) produce rain in laboratories (C) build new laboratories for food research (D) increase the food production or look for other food sources

Article: Tulips are the national flower of Iran and Turkey. The European name for the flower is a misuse of the Persian word for turban , a mistake probably arising in the common Turkish custom of wearing flowers in the folds of the turban. Alternatively, the misuse may have arisen because this eastern flower, when not yet in full bloom, looks like a turban. In Persia, to give a red tulip was to declare your love for someone. The black center of the red tulip was said to represent the lover's heart, burned to a coal by love's passion. Originally growing in the Ottoman Empire (present-day Turkey), tulips were imported into Holland in the sixteenth century. When Carolus Clusius wrote the first major book on tulips in 1592, they became so popular that the tulips in his garden were stolen from time to time. As the Dutch Golden Age grew, so did this colorful flower. They were commonly seen in paintings and at festivals. In the mid-seventeenth century, tulips even created the first economics bubble , known as "Tulip Mania". At that time, tulips were so expensive that they were used as money until the market for them crashed. Today, Holland is still known for its tulips and other flowers, often sincerely called "the flower shop of the world." Tulips are planted in great fields of beautiful color, and transform the landscape into a sea of different colors. Tulip festivals are held throughout the country in spring. However, the most well-known tulip festival is organized in the Noordoostpolder, a province in the central Netherlands, each year. Held in the middle of the tulip fields, this flower festival runs from late April to early May. The Dutch people took their love of tulips abroad when they settled, and tulips and tulip festivals are now found in New York and Michigan, where the connection to their Dutch roots is still very strong.
Question: What can we learn from the text?
Options: (A) Carolus Clusius' book made people import tulips into Holland. (B) Holland is called "the flower shop of the world" because of the tulip. (C) The tulip festival in the Noordoostpolder is sometimes held indoors. (D) Holland is not the birthplace of tulips.
