Read the passage and choose the correct answer to each of the following questions.

1. In China, there are reports that many older people still believe in rumors and pseudoscience. Pseudoscience means things that are said, like facts, but are not proven by science. Recently, more scientists and people discussing science have been using the internet to fight against pseudoscience. However, it's hard for younger people to tell older people about it.

2. For example, last year, Dingxiang Doctor, a digital platform that revealed medical rumors online, released 101 articles that disproved common, inaccurate claims. However, many netizens said that when they forwarded the articles to family chat groups, they were questioned, scolded, and even removed from the group by older family members. An online survey last year by Tencent, one of China's biggest online businesses, indicated that nearly 40 percent of middle-aged and senior people had experienced online fraud, mainly related to healthcare products.

3. Yun Wuxin, who knows a lot about food and has been teaching about it for over ten years, thinks that older people didn't get training in thinking critically when they were young. So, they trust personal experiences, tradition, or superstition a lot. Young people today, though, have better training and question things more. Yun Wuxin says using new media like short videos, video blogs, and animations is excellent for young people. But older people still find traditional ways like TV, visits by scientists, neighborhood shows, and science columns in newspapers essential to understand science.
