Which sentence most clearly functions as a thesis in an argumentative essay?

• A. This essay will discuss several topics.
• B. We should implement stricter recycling programs to reduce waste in our city.
• C. The purpose of this paper is unclear.
• D. In this essay, we will consider recycling.

Answer: (B)

In an argumentative essay, a thesis should present a clear, debatable claim that states the writer’s position and provides a direction for the argument. The sentence arguing for implementing stricter recycling programs to reduce waste in our city does that. It makes a concrete policy recommendation and ties it to a specific outcome, giving the writer a claim to defend with evidence and reasoning. This clarity lets readers know exactly what the essay will argue and why, which is what a strong thesis does.

The other options don’t establish a claim the essay will argue. One merely says the essay will discuss topics, which is neutral and unfocused. Another states the purpose is unclear, which provides no position to defend. The last simply indicates the topic will be considered, without asserting a specific stance or course of action.
