Compare my reasoning
- Place the issue in the period named by the question.
- Select a specific event, group or policy from the syllabus and explain what it changed or caused.
- Link the evidence back to the question and qualify the conclusion where outcomes differed.

Look for these in your work
- Uses a specific syllabus example
- Explains the link to the question
- Keeps the claim within the evidence
How far had US foreign policy changed by 1917?
Give me a hint
Compare earlier involvement with later regional policy and the decision to enter the European war.
Compare my reasoning
- Choose two relevant syllabus details rather than retelling the whole period.
- Explain how each detail supports or limits the proposed explanation.
- Reach a judgement that compares causes, consequences or experiences across time or groups.
By 1917, US involvement had expanded through overseas action, the Spanish–American War, relations with China and Japan, Hawaii, Central and South America, the Panama Canal and policies such as Dollar Diplomacy and the Roosevelt Corollary. Yet debate about involvement in the European war continued. Policy became more assertive, but change was gradual and contested rather than a simple switch from isolation to intervention.
Look for these in your work
- Selects relevant evidence
- Explains causes, change or consequences
- Reaches a balanced judgement
Original practice claim: 'The Panama Canal was built only for humanitarian reasons.' Evaluate it.
Give me a hint
Consider trade and strategic access, then compare other named policies in the region.
Compare my reasoning
- Treat the prompt as an original StudyForA claim, not a historical source.
- Check it against at least two precise syllabus details and identify what the claim leaves out.
- Explain a balanced conclusion and the evidence that would strengthen it further.
The syllabus asks why the Panama Canal was important to the United States and whether regional involvement brought gains. Its strategic and economic value must be considered alongside other policy tools such as Dollar Diplomacy and the Roosevelt Corollary. A single humanitarian motive does not explain the full policy context.
Look for these in your work
- Checks the claim against historical evidence
- Identifies a missing perspective or limit
- States a reasoned conclusion
Common mistakes
- Treating yellow journalism as the only cause of war
- Calling every overseas action humanitarian without examining interests
- Confusing the Teller and Platt Amendments
