Explain why the Republic gave Dave a failing score. What was the motivation for such a cover-up (what did they want from him)? Is this similar to the reasons Eden is being experimented on?

When June reviews Day's case file, she notices that his Trial score of 674 out of 1500 is extremely low. Even children who fail usually score above 800, and June knows Day is extremely smart. She hacks into the database where copies of everyone’s exams are kept. She realizes that all the answers are correct; like June, Day got a perfect score. However, one word is written on his exam: “Attention” (187).

Day's situation might be seen as similar to Eden's because of the way they answered the test questions... meaning they didn't answer the way should have... they were seen as uncompliant.
