I'm taking a test and have to guess the right answer to the question after the article. Article: For the first time, researchers have discovered that some plants can kill insects in order to get additional nutrients. New research shows that they catch and kill small insects with their own sticky hairs near the roots and then absorb nutrients through their roots when the insects are killed and fall to the ground. Professor Mark Chase, of Kew and Queen Mary, University of London, said: "The cultivated tomatoes and potatoes still have the hairs. Tomatoes in particular are covered with these sticky hairs. They do trap small insects on a regular basis. They do kill insects." The number of these carnivorous plants is thought to have came up to 50 percent and many of them have until now been wrongly regarded as among the most harmless plants. Among them are species of petunia , some special tobacco plants and cabbages, some varieties of potatoes and tomatoes, etc. Researchers at Royal Botanical Gardens Kew, which carried out the study, now believe there are hundreds more killer plants than previously realized. It is thought that the technique was developed in the wild to get necessary nutrients in poor quality soil - and even various plants grown in your vegetable garden still have the ability. The researchers, publishing their finding in the Botanical Journal of the Linnean Society, said: "We may be surrounded by many more murderous plants than we think." "We are accustomed to thinking of plants as being immobile and harmless, and there is something deeply frightening about the thought of meat-eating plants," they added.

I'm taking a test and have to guess the right answer to the question after the article. Article: The Friends of the Amazon is a nonprofit association helping to preserve the forest, its wildlife and its native cultures in the Peruvian Amazon. We are located 3 degrees south of the equator in the Region of Loreto, which is roughly the size of Montana and is one of the richest areas in the world in terms of flora and fauna . Our team consists of lawyers, ecologists, sociologists, medical professionals and native Amazonians working together to protect the forest and its people from destruction. We use litigation , filing lawsuits against those who seek to destroy the forest and its native cultures. In addition to legal processes, we promote health, education, and the conservation of native plants and animals. The Amazon Rainforest is commonly referred to as the "lungs of the planet" whose trees are essential for absorbing carbon dioxide (CO2, a greenhouse gas that causes global warming) and it into oxygen, thereby mitigating the rise of global temperatures and climate change. An estimated 120 billion tons of carbon dioxide is absorbed in the Amazon Rainforest and global emissions of carbon dioxide increase with every tree of the rainforest that is cut down. That is why the survival of the Amazon Rainforest is vital for the survival of our planet, without which rising global temperatures could melt the polar icecaps and cause flooding of our coastal cities. Currently, the Amazon is under siege , with an estimated 1000 hectares being destroyed everyday. After harvesting old growth forests, corporations are often replacing the native forest with palm oil plantations instead of reforesting with native tree species. Palm oil trees are native to Africa, not the Amazon, and due to high profits, their promotion by international aid agencies and recent legislation in Peru, palm oil plantations represent perhaps the single greatest threat to the native Amazon Rainforest. In addition to conventional logging and deforesting to make room for crops such as palm oil and soybeans, the Amazon forest faces a new threat... Question: The Friends of the Amazon is the name of _ . Options: A: your best friend B: a non-profit organization C: a historic hero D: a famous carbon cowboy

I'm taking a test and have to guess the right answer to the question after the article. Article: Machu Picchu is considered to be a truly extraordinary archaeological discovery and is one of South America's largest tourist sites. As many as one thousand visitors visit the ancient Incan ruins daily. What draws vacationers and adventurers to this remote location high in the Andes Mountains of Peru ? A large part of the attraction is the mysteries that surround Machu Picchu. For example, Machu Picchu is considered "the lost city" of the Incas because it was never found by Spanish invaders and was known to only a few local peasants for almost four hundred years. The "city in the clouds", Machu Picchu's lasting beauty comes from the careful blending of its striking architecture with its mountaintop environment. Its greatest skill shows are in the stone structures, which equals that of the ancient Egyptians. The stone blocks were so appropriately cut that they fit together without the need for mud. The largest stones at Machu Picchu weigh as much as fifteen tons! It has been difficult to explain how the huge blocks were transported. The buildings, including many that have survived lots of earthquakes, contain stones which _ so perfectly that a knife cannot be forced between them. When compared to other ancient civilizations, it is difficult to understand how Machu Picchu could have been missed by the Spanish and lost from history for four hundred years. For many of the mysteries of Machu Picchu being unsolved, it is clear why Machu Picchu remains "the most famous ruins in all of South America". Question: The purpose of writing the passage is to _ . Options: A: ask us to pay a visit to Machu Picchu B: show us the beauty of Machu Picchu C: introduce Machu Picchu's mysteries D: make the ancient Incan ruins known

I'm taking a test and have to guess the right answer to the question after the article. Article: As any homemaker who has tried to keep order at the dinner table knows, there is far more to a family meal than food. Sociologist Michael Lewis has been studying 50 families to find out just how much more. Lewis and his co-worker carried out their study by videotaping the families while they are having ordinary meals in their own homes. They found that parents with small families talk actively with each other and their children. But as the number of children gets larger,conversation gives way to the parents' efforts to control the loud noise they make. That can have an important effect on the children. "In general the more question-asking the parents do, the higher the children's IQ scores,"Lewis says. " And the more children there are, the less question-asking there is. " The study also provides an explanation for why middle children often seem to have a harder time in life than their siblings . Lewis found that in families with three or four children, dinner conversation is likely to center on the oldest child, who has the most to talk about, and the youngest, who needs the most attention. " _ "says Lewis. When you see someone get up from the table and walk around during dinner,chances are for the middle child. "There is, however,one thing that stops all conversation and prevents anyone from having attention: "When the TV is on,"Lewis says, "dinner is a non-event ". Question: Parents with large families ask fewer questions at dinner because _ . Options: A: they are busy serving food to their children B: they are busy keeping order at the dinner table C: they have to pay more attention to younger children D: they are tired out having prepared food for the whole family
