Section C Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are .four choices marked A), B) , C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre. Passage One Questions 56 to 60 are based on the following passage. 3D glasses help doctors perform invasive surgery when their hands are obscured from view. Moviegoers arent the only ones wearing 3D glasses nowadaysdoctors could benefit from them, too, a new study suggests. In the past, doctors have been skeptical of using 3D technology in their work, preferring to rely on their own experience. But that may change, thanks to improved 3D glasses and even glasses-free systems .Funded by industry sponsors, the study of 50 surgeons using the new technology showed improvements in surgical precision and speed. While the technology still requires some free-tuning, technology without the need to wear special glasses will increase the popularity of 3D systems in operating rooms, study leader Ulrich Leiner of the Fratmhofer Heinrich Hertz Institute in Berlin said in a statement. Improvements to screens are driving developments in 3D technology. High-definition screens are already available. The next step is ultra-high definition, with a sixteen fold improvement in resolution, according to study co-author Michael Witte of HHI. |
