1. Why do you think people in this community don't know the knowledge of science that were already revealed, such as electricity and gravity?
I think the government has concealed the knowledges that were already revealed, so that only they would know it. In other words, they are concealing all knowledge to brainwash the citizens to make them believe that the government knows everything, therefore look up to them and/or fear them. For example, one of my cousins, who is in kindergarten, switched a paper bill of a big value with a small value with his big brother. So, to explain it in Brazilian currency, he switched R$ 100 with R$ 50, because his brother brainwashed him saying that R$ 50 has a bigger value. Likewise, it is easier to brainwash a person if he/she does not have a lot of knowledge, so I think the government is using this fact to brainwash the citizens.
2. Why do you think Ayn Rand made Liberty 5-3000 into a transgressor as well?
In part 4, the author wrote a conversation between Liberty 5-3000 and Equality 7-2521 talking about how they call each other in their minds. Although this is a transgression, both of them gave each other a new name. By doing this, the author somewhat described how the two of them have a similarity that they are different to the other people in the community. Often, when the protagonist of a movie or novel is different to others and is planning to make a change, his/her lover is different, too, and supports the protagonist. I think the author wrote this conversation to give a hint to the readers that Liberty 5-3000 and Equality 7-2521 will make a change together.
3. Do you think Equality 7-2521's discovery will affect the story?
By his discovery, it was told to the readers that Equality 7-2521 is now able to discover new facts of science and he is curious. Also, in the last paragraph, he states that "no single one can possess greater wisdom than the many Scholars who are elected by all men for their wisdom. Yet we can. We do." This describes his curiosity and will to discover more that are hidden. I think he will reveal the facts inside the tunnel that the government is concealing and clearly separate himself from the other people in the community by earning more wisdom than the Scholars.
