(Question)
I'm taking a test and have to guess the right answer to the question after the article. Article: "Keep out or I'll chase you out! This is my property!" You hear this every spring. It is a long musical sound --- a bird song! Birds use their songs to communicate different messages to one another. People who study bird sounds are learning their meanings. Usually it is the male that sings. Early in spring he sings to say that he has picked out a piece of property. He sings to attract a female of his same kind. Together they will raise a family in his territory . He sings to tell all other birds of his kind to keep out. Each kind of bird has its own type of song. Cardinals sing something that sounds a little like "What cheer, cheer, cheer." Towhees sing, "Drink your tea." Most of the time, birds pay attention only to the songs of birds of their own kind. Cardinals answer cardinals, and song sparrows answer song sparrows. A cardinal knows that a song sparrow will not try to steal its mate. So you can see one reason why a cardinal may chase away another cardinal but will not bother a song sparrow. Most different kinds of birds eat different things. To find enough to eat, a bird needs a big piece of land to search in. Many kinds of birds have some ways of dividing up the land into territories. Song sparrows, cardinals ovenbirds, and white-throated sparrows are some of the birds that have territorial systems. Especially in early spring, birds work out the boundaries between their territories by singing "keep out" threats and by chasing and fighting each other. The birds continue singing to tell females that they have set up territories. Neighboring birds seem to agree that there are make believe fences between their pieces of property. Then they do not have to waste energy chasing each other instead of taking care of their young. Scientists guessed that some birds could recognize their neighbors by small differences in their songs. Two scientists who studied white-throated sparrows found that these birds can even tell the difference between songs of individual birds of their own kind. White-throated sparrows... Question: What is the article mainly about? Options: A: How birds build up their territories. B: How birds sing to communicate. C: How male birds chase after females. D: How scientists recognize birds' songs.

I'm taking a test and have to guess the right answer to the question after the article. Article: Much older than the Great Wall, Stonehenge is one of the world's most fascinating, but least understood historical sites. Every year, thousands of tourists come to admire Stonehenge's beauty and to wonder about how and why it was built. Scientists have dated the site, which is located in prefix = st1 /England, to around 3000 BC. The stone circle was constructed in a number of stages over hundreds of years. It took millions of man hours to raise the heavy stones. Though there are many theories, it is still a mystery how stone-age man dragged such heavy stones over 380 kilometers from where they were made. Prehistoric people had only basic wooden tools. To move the stones they probably used tree trunks to roll them along. Some historians believe that Stonehenge was a temple, the site of ancient sacrifices . Others believe it was a burial place or perhaps even a giant sundial to tell the time. Whatever their ancient use was, the stones have always been a source of fascination for British people. One record from 1135 said the great stones were carried to Englandby giant magical creatures! In modern times Stonehenge has become a huge hit with tourists. Question: Tourists are interested in Stonehenge mainly because _ . Options: A: it has something to do with the Great Wall B: they know nothing about its history and site C: nowhere else can they find a stone circle D: most of its history remains a mystery
