Statement–Assumption — “Many historians have done more harm than good by distorting truth.” Assumptions: I) People believe what historians report. II) Historians are seldom expected to depict the truth. Choose the implicit assumption(s).

Introduction / Context:
The charge that distorted history does “harm” presupposes influence: the public or institutions accept and act upon historians’ accounts.

Given Data / Assumptions:

• Claimed effect: net harm due to distortion.
• Mechanism: acceptance of accounts by readers/students/policymakers.

Concept / Approach:
Assumption I is necessary: without public belief, distortion would have little impact. Assumption II is not required and is likely false—the profession’s norm is to seek truth; the statement criticises deviations, not expectations.

Step-by-Step Solution:

Verification / Alternative check:
If no one trusted historians, distortion would be harmless noise—contradicting the statement.

Why Other Options Are Wrong:
“Only II/Both/Neither” either add a needless (and contrary) premise or ignore the influence channel.

Common Pitfalls:
Confusing professional norms with observed misconduct.

Final Answer:
Only assumption I is implicit.
