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 algebraic conditions or variable constraints introduced exclusively within Statement (1) must be completely disregarded.

Answer: Answer

Answer

True. Statement (2) must be evaluated in strict isolation from Statement (1).
Each statement in a Data Sufficiency question must be evaluated independently first. Statement (1) constraints cannot be referenced or assumed during the standalone evaluation of Statement (2).

Step-by-Step Solution

1
Recall the fundamental procedural rules of GMAT Data Sufficiency.
Statement (1) and Statement (2) must be evaluated independently before any combining step is attempted.
Independent evaluation determines whether either statement alone answers the question stem.
2
Apply the rule of independence specifically to the evaluation phase of Statement (2).
When evaluating Statement (2), Statement (1) is treated as non-existent.
Carrying over constraints from Statement (1) creates a false sense of sufficiency for Statement (2) alone.
