Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: Monarch butterflies from eastern Canada make the most amazing journey in the insect world. Each year, this butterfly travels about 3000miles to its winter home in central Mexico . How can it fly so far? And why does it make this long and dangerous trip? Scientists still don't have an answer. For many years, people in Mexico wondered where the orange-and-black butterflies came from every winter. Then, in 1937, a scientist started to follow and study the butterflies. For the next 20 years, he discovered that one butterfly started its journey in Canada. Four months later, it arrived in Mexico. The length of the butterflies find their way back to the same place? Another amazing thing is that the butterflies always return to the same area in central Mexico. How do the butterflies find their way back to the same place? This is an interesting question because only every fourth generation makes the trip south. In other words, the butterfly that travels to Mexico this year is the great-great-grandchild of the butterfly that traveled there last year. Each year, four generations of a Monarch butterfly family are born. Each generation of the family has a very different life. The first generation is born in the south in late April. It slowly moves north, reproduces , and then dies. On the trip north,two more generations are born, reproduce, and die. Each of these generations of butterflies is born. This generation has a much longer life. It lives for about eight months. This generation of butterflies makes the amazing journey back to the winter home of its great-great-grandparents. The butterflies spend the winter there, and in the spring they reproduce and then die. Their offspring will be the first generation of the next circle of life. Today, people are still studying the Monarch butterfly. But they are not clear about everything. Options: A 20 years B four months C five weeks D eight months Answer: A 20 years Question:

A: It took the scientist _ to find out that monarch butterflies came from Canada.

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: A recent research shows that physical activity may help students do better in their classes. The research comes because educators in some countries are reducing time for activities like P.E. class. Researchers go over the results of fourteen studies. Twelve were from the United States, one from Canada and one from South Africa. The studies appeared between 2009 and 2013. They included more than 55,000 children, aged six to eighteen. Thomas Singh, one of the researchers, says the studies showed a relationship between physical activity and scores on subjects such as math, English and reading. Ms. Singh offers some possible explanations : " There are, first, physiological explanations, like more blood flow, and so more oxygen to the brain. Being physically active means there are more hormones( ) produced like endorphins ( ). And endorphins make your stress level lower and your mood improved, which means you will perform better in class. Also, students who take part in organized sports learn rules and how to follow them. This could improve their classroom behavior and help them know what they should do. All in all, the finding tells us that physically active kids are more likely to do better in school. Ms. Singh says schools should consider the finding before they cut physical education programs. Options: A Schools'cutting physical activity. B Their interest in physical activity. C The tests including about 55,000 children. D Kids'unsatisfying schooling performance. Answer: A Schools'cutting physical activity. Question:

A:
What led the researchers to do the studies?
