Questions 46 to 50 are based on the followingpassage.

Open data sharers are still in the minority in manyfields. Although many researchers broadly agree thatpublic access to raw data would accelerate science, most are reluctant to post the results of their ownlabors online.

Some communities have agreed to share online—geneticists, for example, post DNA sequencesat the GenBank repository (库) , and astronomers are accustomed to accessing images ofgalaxies and stars from, say, the Sloan Digital Sky Survey, a telescope that has observed some500 million objects—but these remain the exception, not the rule. Historically, scientists haveobjected to sharing for many reasons: it is a lot of work; until recently, good databases did notexist; grant funders were not pushing for sharing; it has been difficult to agree on standardsfor formatting data; and there is no agreed way to assign credit for data.

But the barriers are disappearing, in part because journals and funding agencies worldwide areencouraging scientists to make their data public. Last year, the Royal Society in London said inits report that scientists need to "shift away from a research culture where data is viewed as aprivate preserve". Funding agencies note that data paid for with public money should be publicinformation, and the scientific community is recognizing that data can now be shared digitallyin ways that were not possible before. To match the growing demand, services are springing upto make it easier to publish research products online and enable other researchers to discoverand cite them.

Although calls to share data often concentrate on the moral advantages of sharing, thepractice is not purely altruistic (利他的). Researchers who share get plenty of personalbenefits, including more connections with colleagues, improved visibility and increasedcitations. The most successful sharers—those whose data are downloaded and cited the mostoften---get noticed, and their work gets used. For example, one of the most popular data setson multidisciplinary repository Dryad is about wood density around the world; it has beendownloaded 5,700 times. Co-author Amy Zanne thinks that users probably range from climate-change researchers wanting to estimate how much carbon is stored in biomass, to foresterslooking for information on different grades of timber. "I'd much prefer to have my data usedby the maximum number of people to ask their own questions," she says. "It's important toallow readers and reviewers to see exactly how you arrive at your results. Publishing data andcode allows your science to be reproducible."

Even people whose data are less popular can benefit. By making the effort to organize andlabel files so others can understand them, scientists become more organized and betterdisciplined themselves, thus avoiding confusion later on.
