Question

when the author writes that whoever develops a plan to make children useful should \have his statue set up for a preserver of the nation,\ he means that the person who solves this problem __________. must pose for a sculptor deserves fame and admiration should be shamed and vilified should be elected to public office

Explanation:

In literature and language - related contexts, setting up a statue is a symbolic act of honoring someone. It is not about literally posing for a sculptor (eliminating the first option). Shaming and vilifying would be the opposite of setting up a statue (eliminating the third option). And there is no indication that it relates to being elected to public office (eliminating the fourth option). Fame and admiration are in line with the idea of being honored with a statue.

Answer:

deserves fame and admiration
