Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: Bai Yansong, a famous TV host, expressed his support for students wearing green scarves at a primary school in Xi'an. He wore a green tie on a TV program on October 19, 2011. "I just want the students to know that I'm also wearing green. And we are all great people and are as good as those wearing red scarves." The First Experimental Primary School in Xi'an made children with poor schoolwork and behavior wear green scarves. Parents whose children wore green scarves were angry. "The children still need their self-esteem even though they are very young, and they know the green scarf means something is not quite right," said one mother. Now, the school has stopped the practice. Educational expert Li Zhenxi said that primary and junior high school students have strong self-esteem. They are eager to be respected and understood. Punishment will hurt them. "It's better to encourage them rather than separating some 'bad' students," he said. A survey made by the Ministry of Education shows that 75 percent of students feel nervous and scared when the teacher is about to announce their grades. Some schools have done better in protecting students' privacy and encouraging them. In American schools, teachers post test results on the wall. Instead of using student names, they use secret numbers. This way, students know their secret numbers and can check their own grades only. Some teachers might call the students up to the desk and tell them their scores one at a time. But test scores are not the only measures of a student's ability. Everyone has his own strengths and everyone can make great progress by working hard. Options: A Primary school students are too young to know what self-esteem is. B Separating some "bad" students helps create good learning environment. C Most "good" students like their teachers to announce their scores. D Using secret numbers instead of students' names can protect their privacy better. Answer: D Using secret numbers instead of students' names can protect their privacy better. Question:

A: According to the article, which of the following is TRUE?

But when bad weather gives you trouble, can you still make it before the bell rings? In northern China during spring, big sandstorms often make trouble for students and everyone else. When the sky is dark with sand, buses and cars all move much more slowly. Sometimes, people can't even see for 20 metres. Sandstorms usually happen in spring. This year, sandstorms started in late March. They have happened in more than 10 provinces in northern China this year. More than 70 million people have had problems in those places because of the sandstorms. People in southern China don't have to worry about this kind of bad weather. Most of the sand comes from Gansu and Inner Mongolia . In northern China, lots of places have few trees and don't get much rain. People there have been cutting down too many trees.

Strong winds take the loose sand into the sky. Sandstorms are bad for people's health. If people breathe too much sand, they could cough or have asthma . Sandstorms also give farmers lots of problems. Sometimes their sheep get lost in the storms and never get back home. The winds also tear down farmers' houses. What can you do to stop sandstorms? Here's an idea: Ask you parents to help you plant some trees this spring. If you see people cutting down too many trees, tell them about the dangers of sandstorms, and ask your government to stop them from cutting. Options: A In spring. B In summer. C In autumn. D In winter. Answer: A In spring. Question:???
