What does the social studies class debate in book speak?

That depends entirely on the book! There's no single answer. A social studies class debate could cover any number of topics, including:

* Current events: A debate might focus on a recent political event, a social issue, or an economic trend.

* Historical events: Students might debate the causes and consequences of a significant historical event, the merits of different historical figures, or the interpretation of historical evidence.

* Government and politics: Topics could include different political systems, the role of government, specific policies, or the rights and responsibilities of citizens.

* Economics: Debates might revolve around economic systems, economic policies, or the distribution of wealth.

* Social issues: Students might debate topics such as inequality, discrimination, environmental issues, or human rights.

To know what *a specific book* depicts as the subject of a social studies class debate, you need to specify the book.
