The electronics company has unveiled what it claims to be the world's smallest network digital camcorder, the length of which is that of a handheld computer, and it weights less than 11 ounces.

Key: to be the smallest network digital camcorder in the wrld, which is as long as a handheld computer, weighting

对于此题，我可以看的出原句的定语从句有误，且weighting 用来表示补充说明，可是to be the smallest network digital camcorder in the wrld 与 be the world's smallest network digital camcorder 有什么区别吗？ the与最高级中间可以加别的东西吗？

望大家指教！

是可以的，如"The World's Smallest Political Quiz。
