Question

Difficulty: MediumStatement Independence Evaluation and Statement Combination

In GMAT Data Sufficiency, when evaluating whether Statement (2) alone is sufficient to answer the question stem, any information or numeric constraints introduced solely within Statement (1) must be completely disregarded.

Answer: Answer

Answer

True
The statement is true because standard GMAT Data Sufficiency procedure requires testing Statement (1) alone, then testing Statement (2) alone in complete isolation, and only combining their information if neither statement alone is sufficient.

Step-by-Step Solution

1
Recall the structural rule for evaluating individual statements in GMAT Data Sufficiency.
Statement (1) and Statement (2) must each be evaluated in complete isolation before any combining phase.
The standard evaluation protocol requires testing whether each statement independently provides sufficient information to answer the question.
2
Analyze whether Statement (1) constraints can be active during Statement (2) standalone analysis.
Statement (1) constraints must be erased from memory when evaluating Statement (2).
Allowing Statement (1) facts to persist during the standalone assessment of Statement (2) causes statement carryover error, leading to incorrect sufficiency conclusions.
