What this topic is asking

Topic 9.2 (skill REO-1.J) covers the heart of synthesis: putting sources in genuine conversation. It asks you to show how the sources relate, agreeing, qualifying, opposing, and to use the tension among them to sharpen your own position. This is the difference between a synthesis essay that lists sources beside one another and one that makes them speak to each other. It builds directly on Unit 3's "how arguments relate" and is a primary route to sophistication.

What "in conversation" means

A synthesis essay where each source appears alone, never touching the others, is parallel summary. A conversation is when one source answers, limits, or complicates another inside your reasoning.

Tension, not stacked agreement

The biggest single failing in synthesis is stacking agreement: choosing only sources that support your view and lining them up. This feels safe but forfeits the tension the rubric rewards. The strongest essays seek out a genuine disagreement or qualification among the sources and engage it, because the conversation sharpens the position.

Using tension to sharpen your position

The payoff of holding tension is a sharper argument. When you concede what an opposing source gets right, then show why your position survives, your position is stronger for having been tested. The conversation does work for you: it surfaces the strongest objection (from a source, ready-made) and lets you answer it, which is exactly the counterargument move that earns sophistication.

Why this matters for the exam

The conversation among sources is what distinguishes upper-band synthesis essays (Question 1) and is a direct route to the sophistication point, which rewards holding genuine tension. The skill is the synthesis-essay form of the counterargument and "how arguments relate" skills from earlier units, now applied to supplied sources. The multiple choice section tests recognition of how a writer uses sources that disagree. Mastering the conversation is the capstone of the whole synthesis strand.

Try this

Q1. Why does stacking agreeing sources stall a synthesis essay? [Recall]

  • Cue. Because it avoids the genuine tension the rubric rewards; lining up only sources that agree shows no engagement with opposition, so the essay cannot reach the upper evidence-and-commentary band or the sophistication point, however many sources it uses.

Q2. A synthesis set on zoos includes a conservationist defending them and an animal-welfare writer opposing them. How would you put these two in conversation to sharpen a position? [Short explanation]

  • Cue. Rather than summarizing each, set them against one another in your reasoning: concede the welfare writer's genuine point that captivity harms some animals, then bring in the conservationist's evidence that zoos sustain endangered species and educate the public, and use the tension to sharpen a qualified position ("zoos are justified only where they prioritize conservation and welfare standards"). The opposing source supplies the strongest objection, your commentary answers it, and the conversation makes your position stronger for having been tested, which earns the upper band and supports sophistication.

AP 2024 (multiple choice, style)1 marksOn the synthesis essay, putting sources in conversation most distinguishes a high score because it (A) increases the word count (B) shows the writer using tension and qualification among sources to develop a position (C) avoids citing sources (D) proves one source right (E) replaces the writer's commentary.

Answer: (B). The skill is making sources interact.

Putting sources in conversation, one qualifying or opposing another, and using that tension to develop a position is what lifts a synthesis essay into the upper band.

Why not the others: (A) length is not the point; (C) sources are still cited; (D) the task is not to vindicate one source; (E) the writer's commentary drives the conversation.

Markers reward genuine interaction among sources, not parallel summaries.

AP 2023 (synthesis, style)6 marksThe sources below present competing views on whether zoos serve a useful purpose. Write an essay developing your position by putting the sources in genuine conversation, using their tensions to sharpen your argument.

Free Response Question 1 (synthesis), 6-point rubric (1 thesis, 4 evidence and commentary, 1 sophistication).

The prompt explicitly asks for conversation and tension.

Thesis (1 point): take a defensible position on zoos.

Evidence and commentary (4 points): set sources against one another, where one qualifies or opposes another, and use the tension within your reasoning.

Sophistication (1 point): hold genuine tension rather than stacking agreement, and show how the conversation refines your position.

The essay rewards real interaction among sources.
