Corroborate a claim across three documents that do not agree
Three steps, the way the exam actually works: work through the lab, write down your own observations, then answer a 8-point free response. What you recorded goes to the grader with your writing, so a conclusion that does not follow from your own evidence will cost you the point — exactly as it would with a real reader.
Predict before you look
- Two documents saying the same thing is not automatically corroboration. Explain in one sentence what else has to be true — think about whether they are independent of each other.
- A document-based question rewards grouping sources rather than listing them. State what makes a grouping analytical rather than a list.
Nothing to submit here — these are to think through, so the prediction below is an informed one rather than a guess.
Commit to an answer now. It is not graded and being wrong costs nothing — the point is to have something specific to reconcile against once you have the data.
Answer every prediction to unlock the lab. A sentence is enough.
Run the investigation
Predictions first
The procedure and the simulation unlock once you have committed above. Observing before predicting is how a wrong intuition survives a lab intact.
Record what you found
This is your reading of the source, not ours. The grader sees them, so your conclusions have to follow from what you actually recorded.

Answer the free response
You have recorded two documents on the survival of popular government, 76 years apart. (a) State the danger each identifies and quote the language that shows it. (b) Explain why Lincoln reaches back to 1776 rather than to 1787, and what that choice tells you about his purpose. (c) Decide whether these two documents corroborate, complicate, or contradict one another on the question of whether popular government can survive, and defend your choice with your own recorded data. (d) Write the grouping sentence you would use in a document-based question that placed both documents together, and explain what makes it analytical rather than a list.
