Read the following article and select the best answer. Article: A patient on the brink of death has received the world's first self--contained artificial heart--a battery--powered device about the size of a softball that runs without the need for wires,tubes sticking out of the chest.It is powered by a small battery pack worn outside the body that transmits current through the skin. Two surgeons from the University of Louisville implanted the titanium and plastic pump during a seven-hour operation at Jewish Hospital Monday.The hospital said the patient was''awake and responsive''Tuesday and resting comibrtably.It refused to eve personal details. The patient had been expected to die within a month without the operation, and doctors said they expected the artificial heart to extend the person's life by only a month.But the device is considered a major step toward inlproving the patient's quality of life. The new pump,called AbioCor,is also a technological leap from the mechanical hearts used in the l980s, which were attached by wires and tubes to large machinery outside the body.The most famous of those, the Jarvic-7,used air as a pumping device and was attached to an apparatus about the size of a washing machine. ''I think it's potentially a major step forward in the artificial heart development,''said Dr.David Faxon,president of the American heart Association.However,he said the dream of an implantable,permanent artificial heart is not yet a reality:''This is obviously an experimental device whose long--term success has to be demonstrated."Only about half of the 4,200 Americans on a waiting list for donor hearts received them last year,and most of the rest died. Some doctors,including Robert Higgins,chairman of cardiology at the Medical College of Virginia in Richmond,said artificial hearts are unlikely to replace donor hearts."A donor heart in a good transplant can last l5 to 30 years.''he said.''It's going be hard replace that with a machine.'' Question: What can we learn about the Jarvic-7? - It is a technological leap today. - It could be used most widely in the l 980s. - It is as advanced as AbioCor. - It must be attached to a washing machine.
It could be used most widely in the l 980s.

Until last year, Lee had been _ .To kill a Mockingbirdsold more than 40 million copies around the world and earned her a Pulitzer prize, remaining a towering presence in American literature. Another novel,Go Set A Watchman, was controversially published in July 2015 as a "sequel" to Mockingbird, though it was later confirmed to be Mockingbird's first draft. But from the moment Mockingbird was published to almost instant success, the author consistently avoided public attention. Lee had lived for several years in a nursing home near the house in which she had grown up in Monroeville, Alabama--the setting for _ of her famous book. Her neighbor for 40 years, Sue Sellers, said, "She was such a private person. All she wanted was privacy, but she didn't get much. There was always somebody following her around." James Naughtie, BBC Books Editor, commented on the novels of Harper Lee: "I think she stands, particularly among American readers, as someone who shone a light into a very dark place. She was writing at a time when people were beginning to lift the lid on everything in the South which they'd chosen not to understand. That all changed in the 1960s. So I think her status for writing that book in its extraordinarily direct way will remain. Question: Which best describes Americans' attitude towards racial troubles before the 1960s? - Tolerant. - Unconcerned. - Sympathetic. - Dissatisfied
Unconcerned.
