Difficulty: Very hardIdentifying Necessary Assumptions

Read the argument below and evaluate whether the provided statement functions as a necessary assumption.

Historian: The invention of writing must have been driven by the need to manage the increasingly complex trade networks of early agricultural surpluses, not by the administrative demands of large-scale monumental building projects. The traditional theory favoring monumental architecture as the primary catalyst is decisively refuted by recent excavations at Oruk, which reveal that complex record-keeping systems were fully established centuries before the construction of any such monuments.

Statement: The administrative demands associated with large-scale monumental building projects did not arise centuries before the actual physical construction of such monuments began.

Answer: Answer

Answer

True. The statement is a necessary assumption.
The correct answer is True because the statement is a necessary assumption required for the argument's logic to hold. The historian concludes that trade networks, rather than monument building, catalyzed the invention of writing. The sole evidence provided is chronological: writing systems were established centuries before any monuments were physically constructed. For this evidence to successfully refute the traditional theory, the historian must assume that the administrative demands of monument building did not precede the actual construction by centuries. We can prove this is necessary using the Negation Technique. If we negate the statement—assuming that the administrative demands did arise centuries before actual construction began, perhaps for long-term resource gathering or site planning—then it is entirely possible that these early administrative demands drove the invention of writing. This destroys the historian's premise that the timeline refutes the traditional theory, which in turn causes the main conclusion to collapse.

Step-by-Step Solution

1
Analyze the structure of the argument.
Conclusion: Trade networks, not monument building, caused the invention of writing. Premise: Writing existed centuries before monument construction began.
Identifying the core logic and identifying any leaps in reasoning is the first step.
2
Identify the logical gap.
The historian assumes that the timeline of physical construction directly mirrors the timeline of its administrative demands.
To refute a causal relationship based on a timeline, the cause itself must not predate the effect.
3
Apply the Negation Technique to the statement.
Negated statement: The administrative demands of monument building DID arise centuries before actual construction began.
The Negation Technique is the definitive test for a necessary assumption.
4
Evaluate the impact of the negated statement.
If the demands arose centuries earlier, they could have caused the invention of writing. The traditional theory survives, destroying the argument's conclusion.
If the logical negation destroys the argument, the original statement is a strictly necessary assumption.
