问题       A famous US climate scientist at the centre of the "climategate’ has been virtually cleared of professional misconduct by an internal university inquiry. Michael Mann of Penn State University featured regularly in the more than 1 000 emails that were hacked from the University of East Anglia (UEA) in the UK last November. His emails and comments have since then featured in countless blogs and news articles. Some have claimed the emails reveal that many climate scientists have changed data in order to demonstrate that climate change is caused by human activities. The scientists in the emails, including Mann, have also been accused of seeking to prevent the publication of doubting research in academic journals.
      Penn State University opened an inquiry into Mann’s behavior in November, shortly after the emails were leaked into the public attention. After going through 1 075 emails and focusing on that were believed relevant to public idea of misconduct by Mann, the inquiry has, by and large, cleared his name. The internal inquiry has found that Mann did not participate in, directly or indirectly, any actions to hide or change data, nor did he remove or otherwise destroy emails, information and/or data relating to Climate Change’s 2007 report. One email that has received much media attention was sent to Mann by Phil Jones, then director of the UEA’s Climatic Research Unit. It asked Mann to delete some emails regarding the 2007 IPCC report.
      The report is not clear about whether Mann’s behavior has harmed the public trust in science, it cites Penn State’s official ethical standards, which says faculty have an obligation to maintain high moral standards in order to raise public trust in science. It then goes on to discuss the fallout from the email leak which, it says, may have driven the public into two camps: one that believes the leak harms climate science and another that does not. "After careful consideration of all the evidence and relevant materials, the inquiry committee could not make a definitive finding whether there exists any evidence to prove that Dr. Mann did engage in, or participate in, directly or indirectly, any actions against accepted academic practices," reads the report. This final point will now be at the centre of a further investigation.
      "This is very much the proof I expected since I am confident I have done nothing wrong," Mana told New Scientist. "I fully support the additional inquiry which may be the best way to remove any remaining doubts."
Mann’s emails and comments was claimed to show that many climate scientists ______.

选项

答案have changed data

解析 细节辨认题。本题考查一些博客和新闻对某些气象学家学术不端的怀疑。原文指明,有人声称这些电邮表明,很多气象学家篡改了数据以说明气候变化是由人类活动造成的,故答案为have changed data。
