Answer:
- "This was not what they had aimed at when they had set themselves years ago to work for the overthrow of the human race."
- "... they were far better off than they had been in the days of Jones, and that before all else it was needful to prevent the return of the human beings."
Explanation:
1. This statement support the theme especially looking at the ending part which says, "they had set themselves years ago to work for the overthrow of the human race". We note that the perceived oppression they experienced prompted them to act, but despite acting they were still struggling with the alternative course of action.
2. The statement "they were far better off" indicates that they experienced oppression "in the days of Jones".
Thus, after their ordeal they were determined more than ever to avoid the alternative of not preventing the return of the human beings.
