Part A
The principal values the consistency of the robot students.
Part B
The two excerpts that best support the answer are:
- "Of course, it was possible to switch subjects around somewhat to take arithmetic before history, or, in place of one rule of grammar, to take another." (paragraph 11)
- "Indeed, the principal was so content with this state of affairs that he not only praised the teacher highly, but even gave her a promotion." (paragraph 11)
These excerpts suggest that the principal appreciated the structured, consistent nature of the robot students' education and was satisfied with the current system.
