What is the survey or questionnaire of the two articles by Andreea Popescu, all animals are equal and mikhail bishop, Effectives of orwell's time period and cultural situations in Animal Farm?

Instead, their research methods involve:

• Textual analysis: A close reading and interpretation of George Orwell's Animal Farm itself.
• Historical research: Examining historical events (like the Russian Revolution) and the cultural/political climate of Orwell's time.
• Literary theory: Applying critical frameworks to understand the themes, characters, and author's intent within the novel.

Popescu's article likely analyzes how the theme of "all animals are equal" is presented and subverted in the text, while Bishop's article would draw connections between the novel's narrative and the specific historical and cultural situations of Orwell's era.
