"mankind was my business"
Snowball wanted that every animal on the farm be treated the same, no matter the size, or what type they were. He exectued his plans in a way that every animal did their own share of work, and were rewarded for doing such. Napoleon also had this same idea, but was eventually corrupted with the luxuries of the house. Napoleon eventually started to work the animals just like the farmer had done. This reflects their differing goals because it shows the true nature of each character - Snowball, the ready leader. And Napoleon, the corrupted ruler who eventually turned on what was once his views.

The sentence has a vague pronoun problem because it is unclear if the police officer or the criminal tripped and fell. In order to correct this, the sentence needs to be more specific. We can say any of the following sentences:
The police officer chased the criminal through the streets until <u>the officer </u>tripped and fell.
- It is clear that the officer fell.
The police officer chased the criminal through the streets until <u>the criminal </u>tripped and fell.
- It is clear the criminal fell.
This sentence wouldn't necessarily work with the original sentence since we can infer that only one of them fell because the writer used he. However, if both of them fell, it would be correct as well.
The police officer chased the criminal through the streets until <u>they</u> tripped and fell.
