Q: I'm taking a test and have to guess the right answer to the question after the article. Article: More often than not, the person sitting next to you on a plane or sleeping in the next hotel room has paid more or less than you did for the same services. Each day, airlines give more than several hundred fares for flights between the same two cities and hotels charge different rates for the same room. So how do you find the best rates? Here are some tips: ^ Sign up for fare special e-mails. When airlines get into a fare war, the cost of a plane ticket can fall overnight and the discounted fare may be sold out by noon the next day. Get on the mailing list of airlines and other travel Web sites so you can be told immediately if fares drop. ^ Buy your tickets at least 21 days in advance. There are usually four different timetables for advance tickets: 21-day, 14-day, 7-day, and 3-day. The further in advance you book your flight, the lower the fare you will find. ^ Consider another airport. Find out about all the airports that are near your destination city. You might be able to fly into a smaller airport or neighboring city at a much lower rate. ^ Stay over a Saturday night. Airlines give the highest fares to business travelers, who fly during the week and spend their weekends at home. If you plan to leave for your trip on a Wednesday and return on Saturday, your fare would be a lot higher than you stay until Sunday morning. ^ Fly on Tuesdays, Wednesdays, and Saturdays. Some airlines offer cheaper fares on different days of the week. Generally, it's the cheapest to fly on Tuesday, Wednesday, and Saturday. Remember, though, that a Saturday stay is necessary to receive the lowest rate. ^ Pick a flight with plenty of open seats. Seats in a flight are divided into "classes", and each class has its own price. Since the cheapest classes sell first, the fewer seats that are left on a plane, the more expensive they are. Question: This passage is mainly about _ . Options: A: how to keep yourself safe during your flight B: how to choose a better and more comfortable airline C: how to spend less when traveling by air D: how to book your air ticket in advance

Q: I'm taking a test and have to guess the right answer to the question after the article.

He got away from their backyard during the storm. Chuck James said that his family searched for the brown-and-white dog named Reckless for months after the October 2012 storm.

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Redwood trees are the tallest plants on the earth,reaching heights of up to 100 meters.They are also known for their longevity,typically 500 to 1000 years,but sometimes more than 2000 years.A hundred million years ago,in the age of dinosaurs,redwoods were common in the forests of a much more moist and tropical North America.As the climate became drier and colder,they declined to a narrow strip along the Pacific coast of Northern Califomia. The trunk of redwood trees is very strong and usually forms a single straight column.It is covered with a soft bark.This bark can be pretty thick,well over two feet in the more mature trees.It gives the older trees a certain kind of protection from insects,but the main benefit is that it keeps the center of the tree harmless from moderate forest fires because of its thickness.This fire resistant quality explains why the giant redwood grows to live that long.While most other types of trees are destroyed by forest fires,the giant redwood actually prospers because of them. Moderate fires will clear the ground of competing plant life,and the rising heat dries and opens the ripe fruit of the redwood,releasing many thousands of seeds onto the ground below. New trees are often produced from shoots,little baby trees,which form at the base of the trunk.These shoots grow slowly,fed by the root system of the "mother'' tree.When the main tree dies,the shoots are then free to grow as full trees,forming a "fairy ring" of trees around the original tree.These trees,in turn,may give rise to more shoots,and the cycle continues. Question: How does a "fairy ring'' form according to the passage? Options: A: By killing an old tree. B: By connecting root systems. C: By inserting holes into old trees. D: By surrounding a mature tree.
