问题 　　As he applied sunscreen to his young daughter’s face, Dara O’Rourke,
professor of environmental and labour policy at the University of California,
Berkeley, found him wondering if the lotion was safe. He realized there was【S1】________
no ready available answer. The result—two years, a team of chemists, lots【S2】________
of testing and a chunk of venture capital later—is GoodGuide.com.
Launched in 2008, this is a website and smart phone app that rates 140,000
consumer products (currently only in America) according to their safety,
environmental sustainability and the ethics of the firms that make them.
Now GoodGuide has created a new "purchase analyser" app designed to
inform consumers not just about the values embedding in products, but also【S3】________
about whether they are the virtuous shoppers they say they want to be.
Using the new app requires selecting a series of characteristics, that can【S4】________
range from whether the user favours organic products to buy only from firms【S5】________
with a good human-right record. The consumers then scan the barcode on【S6】________
product with the camera in their smart phone. The app identifies it and【S7】________
checks in a database to score how it shapes in. 【S8】________
　　Much however depends on the quality of the data, which GoodGuide【S9】________
gathers from various sources, including government reports and scientific studies,
and research by its own staff. If the product scores badly, the app will recommend an
alternative item which is rated more highly. The app also tracks a
consumer’s purchases to see how well they fit in with their【S10】________
selected values, giving a sort of personal virtue (or hypocrisy) rating.
【S9】
选项
答案however→therefore
解析 连词误用。该句意为“因此，数据库提供的信息就十分重要了。这些数据库中的资料来源各种各样，包括政府报告、科学研究及其员工所做的调查。”此句与上一段有明显的因果关系而非转折关系，故应将however改为therefore。
