Which of the following is correct? ( )

参考解析：

根据倒数第二段，Rogeberg notes that humans will still need to process information, even as technology and artificial intelligence become a bigger part of people's lives.可知A错误。B项说法过于绝对，排除。C项定位第三段，The men were given tests around age 18 to measure IQ—or intelligence quotient—as part of required military service in Norway.可知正确。第九段，the genes that the first born and the second born and the third born get, they will be relatively similar.可知是基因相似，并不能替换为智商相似，D项错误。故本题正确答案选C。
