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 Two Thinking small, being engaging, and having a sense of humor don’t hurt. Those are a few of the traits of successful science crow d funding efforts that emerge from a recent study that examined nearly 400 campaigns. But having a large network and some promotional skills may be more crucial. Crow d funding, raising money for a project through online appeals, has taken off in recent years for everything from making movies to producing water-saving gadgets. Scientists have tried to tap Internet donors, too, with mixed success. Some raised more than twice their goals, but others have fallen short of reaching even modest targets. To determine what separates science crowdfunding triumphs from failures, a team led by science communications scholar Mike Schäfer of the University of Zurich examined the content of the webpages for 371 recent campaigns. Four traits stood out for those that achieved their goals, the researchers report in Public Understanding of Science . For one, they use a crowdfunding platform that specializes in raising money for science, and not just any kind of project. Although sites like Kickstarter take all comers, platforms such as Experiment.com and Petridish.org only present scientific projects. For another, they present the project with a funny video because good visuals and a sense of humor improved success. Most of them engage with potential donors, since projects that answered questions from interested donors fared better. And they target a small amount of money. The projects included in the study raised $4000 on average, with 30% receiving less than $1000. The more money a project sought , the lower the chance it reached its goal, the researchers found. Other factors may also significantly influence a project’s success, most notably, the size of a scientist’s personal and professional networks, and how much a researcher promotes a project on their own. Those two factors are by far more critical than the content on the page. Crowdfunding can be part of researchers’ efforts to reach the public, and people give because “they feel a connection to the person” who is doing the fundraising — not necessarily to the science.
