Article: Forty-two of the fifty American states offered some kind of public online learning this past school year.One state,Michigan,now requires all students to have an online learning experience before they finish high school.Even the idea of a school has changed since the rise ofthe Internet in the 1990s. A new report from the Center for Evaluation and Education Policy at Indiana University says eighteen states have full-time virtual schools.There are no buildings.All classes are online. Florida started the first statewide public virtual school in the United States in 1997.Today,the Florida Virtual School offers more man ninety courses.56,000 students were enrolled as of December.Almost sixty percent were female.The school's website says each student was enrolled in an average of two classes. Florida Virtual School has now opened the Florida Virtual Global School.Students in other countries pay for classes.Janet Heiking teaches an English class.She lives in Indianapolis, Indiana.Her students live as far away as Africa and Japan.She says they are taking her Advanced Placement class to prepare for attending an American college.They can earn college credits by passing the AP test. So how good are virtual schools? Studies have shown mixed results, as a new report from Indiana University notes.For example, students at Florida Virtual School earned higher grades than those taking the same courses the traditional way.And they scored higher on a statewide test.But virtual school students in Kansas and Colorado had lower test scores or performed at a lower level than traditional learners.Studies also find that virtual schools may not save much in operating costs. Education experts say the mixed results suggest the need for more research to find the best ways to teach in virtual schools.A1so, they say schools of education need to train more teachers to work in both real and virtual classrooms. Question: Florida Virtual School is open to _ . Yes or no, is the answer "students across the world"?
Yes

One of his legs was broken and he had to be in hospital. He said to the nurse, "I'm a poor man, madam. Arrange a third-class ward for me, please." "Can't anybody help you?"

Article: Scientists in Canada say big ocean fish have almost disappeared from the world since the start of industrial fishing in the nineteen-fifties. The scientists found that population of large fish like tuna; swordfish and cod have dropped by ninety percent in the past fifty years. The study took ten years. The researchers gathered records from fishing businesses and governments around the world. The magazineNaturepublished the findings. The scientists say the common method called longline fishing is especially damaging to populations of large fish. This method involves many fishing lines connected to one boat. These wires can be close to one-hundred kilometers long. They hold thousands of sharp metal hooks to catch fish. Longline fishing is especially common in the Japanese fishing industry. Records showed that Japanese boats used to catch about ten fish for every one-hundred hooks. The study says longline fishing boats now might catch one fish per hundred hooks. The scientists say industrial fishing can destroy groups of fish much faster than in the past. The study suggests that whole populations can disappear almost completely from new fishing areas within ten to fifteen years. Ransom Myers of Dalhousie University in Nova Scotia led the study with Boris Worm of Dalhousie and the University of Kiel in Germany. Mister Worm says the destruction could lead to a complete re-organization of ocean life systems. Mister Meyers says the decreased number of large fish is not the only worry. He says even populations that are able to reproduce do not get the chance to live long enough to grow as big as their ancestors . He says not only are there fewer big fish, they are smaller than those of the past. American government scientists say even with the best efforts to protect fish populations, decreases are to be expected. Question: Big fish have gradually been disappearing especially because _ . Yes or no, is the answer "longline fishing method is used"?
No
