Question 19 is based on the passage you have just heard.

        Despite smartphones and social media, young people today are as socially competent as those from the previous generation. At least, this is what a new study suggests. For the study, researchers compared teacher and parent evaluations of American children who started kindergarten in 1998 with those who began school in 2010. The former group entered kindergarten when mobile phones were luxuries. The latter group started school when mobile devices were widespread. (19) [Results showed both groups of children were rated similarly on important social skills.] These included the ability to form and maintain friendships and get along with people who are different. They were also rated similarly on self-control, such as the ability to regulate their temper. In virtually every comparison made, ratings of social skills either remain constant or improved for the children born later. There was one exception: (20) [social skills were slightly lower for children who accessed online games and social networking sites many times a day.] (21) [Adults are worried when technological change starts to undermine traditional relationships, particularly the parent-child relationship.] The introduction of telephones, automobiles and radio all led to moral panic among adults of the time, because the technology allow children to enjoy more freedom. Fears over screen-based technology represent the most recent panic in response to technological change. But overall, the study found little evidence that time spent on screens was hurting social skills for most children.

19. What does the new study suggest about young people today and those from the previous generation?（对于今天的年轻人和上一代的年轻人，这项新研究表明了什么？）

解析：D。录音中间提到，研究结果显示，两组儿童在重要社交技能方面的评分相近。D项与此内容相符，其中的are similar对应录音中的were rated similarly，social skills原词复现，故为正确答案。

错项排除：录音中提到，上一代在开始上幼儿园时，手机仍是一种奢侈。而当今一代人开始上学时，移动设备已经普及，因此并不是两个群体都花了很多时间在移动设备上，故A项排除。录音中没有提到两个群体对社会关系的重视程度以及使用新技术的能力，故排除B项和C项。
