Write a multi-choice question for the following article, with the given choices and answer: Article: London-Lazy students can now give up on work altogether as two Oxford University students have made scores of A-grade essays on the website for students to copy. The essays are on the new website, "revise.it" The website includes an "EssayLab" designed to make cheating as effective and effortless as possible. Its homepage announces to surfers : "The revise.it EssayLab is a bank of hundreds of A-Level essays covering popular topics." "Next time you are asked to write an essay, why not see what we have on the subject-if you are in a lazy state of mind you can even use our guide to writing the essays and then just hand them in." Nick Rose and Jordan Mayo, both 19 and first from Manchester, spent much of their first year as students at the university setting up the website. There is no charge for downloading the essays. "I have never been very good at essay writing," Rose admitted. "We don't see essay bank as a cheating way. It's a surprising valuable resource. You can learn a lot by reading other people's work on the subject." Among other tips, the website suggests inventing important speeches to give essays extra weight: "Popular people to quote are Douglass Hurd or Disraeli." Hurd was a foreign secretary in the 1980s and Disraeli was a 19 century prime minister. Teachers are expressing their opinions by e-mail that they are angry about the website that "encourages students to cheat", but students disagree. According to Rose: "Exams are a fight. It's us against them." Options: A it is difficult for students to pass their exams B it is difficult for teachers to finish their teaching C students are not satisfied with the education system D students are too lazy to learn anything Answer: C students are not satisfied with the education system Question:

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Scientists have devised a way to determine roughly where a person has lived using a strand ( ) of hair, a technique that could help track the movements of criminal suspects or unidentified murder victims. The method relies on measuring how chemical variations in drinking water show up in people's hair. "You're what you eat and drink, and that's recorded in your hair," said Thure Cerling, a geologist at the University of Utah. While U.S. diet is ly identical, water supplies vary. The differences result from weather patterns. The chemical composition of rainfall changes slightly as rain clouds move. Most hydrogen and oxygen atoms in water are stable, but traces of both elements are also present as heavier isotopes ( ). The heaviest rain falls first. As a result, storms that form over the Pacific deliver heavier water to California than to Utah. Similar patterns exist throughout the U.S. By measuring the proportion of heavier hydrogen and oxygen isotopes along a strand of hair, scientists can construct a geographic timeline. Each inch of hair corresponds to about two months. Cerling's team collected tap water samples from 600 cities and constructed a map of the regional difference. They checked the accuracy of the map by testing 200 hair samples collected from 65 barber shops. They were able to accurately place the hair samples in broad region roughly corresponding to the movement of rain systems. "It's not good for pinpointing ( )," Cerling said. "It's good for eliminating many possibilities." Todd Park, a local detective, said the method has helped him learn more about an unidentified woman whose skeleton was found near Great Salt Lake. The woman was 5 feet tall. Police recovered 26 bones, a T-shirt and several strands of hair. When Park heard about the research, he gave the hair samples to the researches. Chemical testing showed that over the two years before her death, she moved about every two months. She stayed in the Northwest, although the test could not be more specific than... Options: A A map showing the regional difference of tap water. B A collection of hair samples from various barber shops. C A method to measure the amount of water in human hair. D A chart illustrating the movement of the rain system. Answer: A A map showing the regional difference of tap water. Question:
