Question: Write a multi-choice question for the following 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.
Answer: 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.Answer:D

Question: Write a multi-choice question for the following article: Article: School violence is in the headlines again after recent shootings at schools in Pennsylvania, Wisconsin, and Colorado. After hearing the news, it's natural for students -- no matter how old they are or where they go to school -- to worry about whether this type of incident may someday happen to them. So how safe are schools? It's actually safer to be in a school than in a car. Twice as many 15-to-19-year-olds die in car accidents than in shootings (and that's all shootings, not just the ones that happen in schools). According to the Centers for Disease Control and Prevention, less than 1% of all homicides among school-age children happen on school grounds or on the way to and from school. So the vast majority of students will never experience violence at school. However, some schools have re-evaluated their safety needs in response to the concerns of families and communities. Some now require that guests check in at the office or have more guards on duty. Some schools have fixed metal detectors. Another thing that helps make schools safer is greater awareness of problems like bullying and discrimination. Many schools have practiced programs to fight these problems and to help teachers and administrators know more about protecting students from this type of violence. The cause of school violence isn't easy to understand. There is no single reason why students become violent. Some are just copying behavior they've seen at home, in the streets, or in video games, movies, or television. There's one thing experts do agree on, though: Having access to guns or other weapons makes it easier for some people to lash out against the things or people they don't like.
Answer: Question: After schools have re-evaluated their safety needs, _ .Options:A families will be more concerned about schoolsB communities will be responsible for schoolsC teachers will pay more attention to shootingsD administrators will arrange to have more guards on dutyAnswer:C

Question: Write a multi-choice question for the following article: Article: Mary Jean Price Walls graduated second in her class in 1950.She had high hopes when she applied to a local college,Southwest Missouri State College.But after sending off her application,she spent months waiting for a reply.It never came. Worse than simply being denied admission ,the school didn't reply to her at all.It wasn't a matter of her school records,but of her skin color:Wallsis African American,and in those days,that fact alone closed a lot of doors. "I was sad and I was hurt,"Walls toldABCNews."I did not expect the skin color would affect my application.I thought I could go to university like other students." Four years later,the government declared that all schools should not discriminate against African Americans-- but it was too late for Walls.She'd moved on with her life, becoming a wife and a mother,and working as an elevator operator.She retired last year,at the age of 77. She stayed quiet about the unfairness she'd faced in Missouri State.Her son,Terry,went through school records and found that she'd been the first black student to ever apply to the college.Today,four percent of the Southwest Missouri State College body is African American--including Terry. Although it's too late for Missouri State to change the past,the school is awarding Walls with an honorary degree from the school.While she knows it's too late for herto change the course of her own life with the degree,it's a chance for her to show her family that Missouri State has changed in the last 60 years,and there's not a single door closed to them anymore.
