55. What motivates people to donate in a crowdfunding campaign?
- A. The ease of access to the content of the webpage.
- B. Their desire to contribute to the cause of science.
- C. The significance and influence of the project itself.
- D. Their feeling of connection to the scientists themselves.
答案：D
答案句：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.
参考译文：众筹可以是研究人员接触公众努力的一部分，人们捐款是因为“他们感觉与筹款人本人有联系”——不一定是与科学有联系。
定位线索：题干“motivates people to donate”→答案句“people give because”；文中“feel a connection to the person”对应选项D“feeling of connection to the scientists themselves”；文中“not necessarily to the science”排除选项B和C。
解析：题干问捐款动机，答案句明确说“people give because they feel a connection to the person”，即与科学家本人的联系，对应选项D。选项B“为科学事业做贡献”和选项C“项目本身的意义和影响”都被“not necessarily to the science”否定；选项A“网页内容易获取”无中生有。
