I'm taking a test and have to guess the right answer to the question after the article. Article: Blue whales are the largest animals ever known to have existed on the planet, and they can grow to a length of 100 feet and weigh more than 330,000 pounds. But recently researchers have found that these whales are on the move and they have migrated (moved) from California waters to areas off Canada and Alaska for the first time since commercial whaling ended in 1965. The researchers identified 15 blue whales that have appeared off the coast of British Columbia and the Gulf of Alaska since 1997. Four of these whales were recognized as ones that were once sighted off California shores, suggesting that the whales are returning to an old migration pattern between the coasts. Before commercial whaling began in the early 1900s, blue whales were found widely throughout the North Pacific and California waters. But from the 1920s to the 1960s, whaling severely reduced the whale populations. Blue whales never recovered in the Northern Pacific, making sightings in this area rare. However, much larger groups of whales have been observed close to California since the 1970s. The scientists had previously thought that the California population was separate from the population that had historically lived in North Pacific waters. But the current study shows that whales off the coast of British Columbia and the Gulf of Alaska are likely part of the California population.[:] To identify the blue whales, the researchers looked at photos of _ taken in the North Pacific Ocean and compared them with a library of blue whale pictures taken along the West Coast of the United States and Southern Pacific. Up to now, the researchers are not quite sure why the whales are changing their migration patterns, but they suspect that the whales may be following their food moving farther north by the changes in ocean conditions. Question: The whale population in the northern Pacific _ . Options: A: is different from the California population B: has become the largest group since the 1970s C: is probably part of the California population D: has lived there since the 1960s.

Article: Once in a village, the villagers built a new church building and people came from far and wide to see it. They admired its beauty! They said it was the most beautiful building in the world. Up on the roof, a little nail heard the people praising everything about the lovely structure - except the nail! No one even knew he was there, and he became very angry and sad. "If I am not important, nobody will miss me if I quit!" So the nail then released its hold, got down from the roof, and fell into the mud. That night it rained and rained. Soon, the board that had no nail was blown away, and the roof began to leak . The water flowed down along the walls and over the beautiful pictures on the walls. The plaster began to fall, the floor was ruined, and the Biblewas also ruined by water. All this was because a little nail decided to quit! But what of the nail? While holding the board, it was not known by others but it was useful. Buried in the mud now, it was useless and would soon be eaten up by rust!

I'm taking a test and have to guess the right answer to the question after the article. Article: SAN FRANCISCO--A phone app in San Francisco gives information about open parking spots. City officials in San Francisco introduced the app to try to reduce traffic jams in the city, but some say it raises safety concerns. In this city, drivers searching for parking spots lead to 30 percent of all downtown jams, city officials think. Now San Francisco has found a solution--a phone app for spot-seekers that displays information about areas with available spaces. The system, introduced last month, relies on wireless sensors fixed in streets and city garages that can tell within seconds if a spot has opened up. Monique Soltani, a TV reporter, said she and her sister spent 25 minutes on Friday trying to park. "We were praying to the parking god that we'd find a spot," she said. "If we had the app, we would not have to pray to the parking god." But the system could come with serious consequences. Some people say that drivers searching for parking could end up focusing on their phones, not the road. "It could be really distracting ," said Daniel Simons, a professor of psychology at the University of Illinois. City officials acknowledge the potential problem. They are urging drivers to pull over before they use the city's iPhone app, or to do so before they leave home. Nathaniel Ford, executive director of the San Francisco Municipal Transportation Agency, said safety could actually improve if drivers quickly found a spot instead of circling and getting frustrated. San Francisco has put sensors into 7,000 parking spots and 12,250 spots in city garages. If spaces in an area open up, the sensors communicate wirelessly with computers that in turn make the information available to app users within a minute, said Mr. Ford, of the transportation agency. On the app, a map shows which blocks have lots of places (blue) and which are full (red). More than 12,000 people have downloaded San Francisco's app, which is available now only for the iPhone but which city officials say they hope to bring to all similar... Question: According to the text, San Francisco city officials _ . Options: A: don't consider the app distracting B: advise drivers to park cars slowly C: are aware of the app's disadvantages D: believe more parking spots are needed

I'm taking a test and have to guess the right answer to the question after the article. Article: Traveling without a map in different countries,I find out about different"styles"of directions every time I ask "How can I get to the post office?" Foreign tourists are often confused in Japan because most streets there don't have name signs:in Japan,people use landmarks in their directions instead of street names.For example,the Japanese will say to travelers,"Go straight down to the corner.Turn left at the big hotel and go past a fruit market.The post office is across from the bus stop." People in Los Angeles,the US,have no idea of distance on the map:they measure distance by time,not miles."How far away is the post office?"you ask."Oh," they answer,"it's about five minutes from here." You don't understand completely,"Yes,but how many miles away is it,please?"To this question you won't get an answer,because most probably they don't know it themselves. People in Greece sometimes do not even try to give directions because tourists seldom understand the Greek language.Instead,a Greek will often say," Follow me."Then he'll lead you through the streets of the city to the post office. Sometimes a person doesn't know the answer to your question.What happens in the situation? A New Yorker might say,"Sorry, I have no idea."But in Yucatan,Mexico,no one answers "I don't know." People there believe that "I don't" is impolite.They usually give an answer,but often a wrong one.So a tourist can get lost very easily in Yucatan! However,one thing will help you everywhere in the world.It's body language. Question: How do Greeks give directions? Options: A: Using street names. B: Using landmarks. C: Leading people the way. D: Giving people a wrong direction.
