1) Natural behavior, that is to say irrational and unrestrained, was considered good in contrast wt rational behavior.
2) Humble people were considered unspoilt by civilization.
The term "Victorian" comes from the (is the necessary?) queen Victoria, who ruled over England from 1837 to 1901.
3)The depiction of Sissy and Bitzer is reached through their description (what does it mean?)
4)Childhood was the nearest to God and the purest part of society.

1) Natural behavior - that is, irrational and unrestrained behavior - was considered good in contrast with rational behavior.

2) Humble people were considered unspoiled by civilization.
The term "Victorian" comes from the era when Queen Victoria ruled over England from 1837 to 1901.

3) The characterization of Sissy and Bitzer is accomplished mainly by the author's description of them. (characterization = the way in which an author develops a character)

4) Childhood was the nearest to God, and children were considered the purest part of society.
