Step-by-step explanation:
The statement of the question is not properly organized. The passage and options are scattered. So, I assume all the options are for one same question (and one passage)
"The Animal Farm" is an allegorical novel written by and English writer George Orwel (1903-1950). It parodies Soviet government mainly during 1920's under Joseph Stalin. Napoleon, the villain is portrayed as Stalin) and Squealer as Vyacheslav Mikhailovich Molotov serving as a diplomat and politician.
The options of "deflecting blames" and "economic gain" are not mentioned in this passage but in other parts of the novella. The dogs don't speak in the novella, they just threaten the animals.
