Read the following article and select the best answer. Article: Drawings of human colonies on other planets often picture the entire community under a glass or plastic bubble. The bubble is intended to create an atmosphere with adequate oxygen and other essential elements. But similar bubble-like structures have also been constructed on earth. One of the most famous, and controversial, is a site in the Arizona desert. Biosphere 2, as it is called, was built not far from Tucson in 1984 and is now run by Columbia University. This huge(7,200,000-cubic-foot)glass and steel construction contains several separate ecosystems, including a desert, a rain forest, and a 900,000-gallon "ocean." The climatic conditions-humidity, temperature, air quality-are regulated by sensors and can be adjusted as needed or desired. For example, a rainstorm can be created to increase the humidity. The adjustable features of Biosphere 2 make it an ideal location to perform experiments to help determine the effects of such climatic changes as global warming. The current conditions at Biosphere 2 are vastly different from those in 1993, when eight people who had moved into the environment with great fanfare two years earlier moved out in failure. Though promising to be self-sufficient , these "colonists" had so much trouble regulating the environment that they reportedly had food smuggled into them. Oxygen levels became dangerously low; most plants and animals died. In taking over the unsuccessful site, Columbia hopes to erase its notorious past by focusing on small research projects that gradually answer some of Biosphere 1's -- that is, Earth's most basic environment questions. Question: This passage primarily deals with _ . - conditions of life in Biosphere 2 - building controlled environments on other planets - why Biosphere 2 failed in the past - what makes a good biosphere colonist
conditions of life in Biosphere 2

*Question*
Read the following article and select the best answer. Article: For as long as they can remember Jynne Martin and April Surgent had both dreamed of going to Antarctica.This winter,they each made it to the icy continent as guests of the National Science Foundation(NSF).Bm they didn't go as scientists.Martin is a poet and Surgent is an artist.They went to Antarctica as participants.in the NSF's Artists and Writers program.The NSF is thegovernment agency that funds scientific research in Antarctica.But it also makes it possible for artists,including filmmakers and musicians,to experience Antarctica and contribute their own points of view to our understanding of the continent. The mixing of science and art in Antarctica isn't new.Some of the earliest explorersbrought along painters and photographers.Edward Wilson was a British painter,doctor,and bird expert who journeyed with RobertFalcon Soott on two separate Antamtic expeditionsmore than 100 years ago.Herbert Ponting was a photographer who also accompanied Scott on one of those expeditions.In hundreds of photos,Pontingcaptured the beauty of the continentand recorded the daily lives and heroic struggles of the explorers. Today's scientists write articles forscientificjournals.Unlike theearly explorers'journals,scientific papers can now be very difficult for non-scientists to understand.Writers in Antarctica workto explain the research to the public.Peter Rejcek is editor,writer,and photographer for the Antarctic Sun,an onlinemagazine devoted to news about the U.S.Antarctic Program.Rejeck began his career in the Antarctic in 2003 by spending a year at the South Pole.He has returned everyyear since,interviewing,scientists about research at Palmer,McMurdo,and South Pole stations. There are also scientists in Antarctica who work hardto explain their research to the public.Scientist Diane McKnight wrote The Lost Seal,a children's book that explains the research she and others are doing in an unusual ice-free area in Antarctica called the Dry Valleys. Antarctica is full of stories and wonders that are scientific,historic.and...
