Zorluk: KolayStatement Independence Evaluation and Statement Combination

When evaluating Statement (2) in a GMAT Data Sufficiency question, information introduced solely in Statement (1) may be used to analyze Statement (2) as long as Statement (1) is independently insufficient.

Cevap: Cevap

Cevap

The statement is false. Statement (2) must always be evaluated in complete isolation from Statement (1).
The statement is false because GMAT Data Sufficiency rules require that Statement (2) be evaluated completely independently of Statement (1). Information from Statement (1) cannot be used to help evaluate Statement (2) alone; the two statements are only combined during a joint evaluation stage if both statements have already been proven insufficient on their own.

Adım Adım Çözüm

1
Recall the fundamental rule of statement evaluation in GMAT Data Sufficiency.
Statement (1) and Statement (2) must each be evaluated independently of one another.
This determines whether either statement alone is sufficient to answer the question before any combination is attempted.
2
Analyze whether information from Statement (1) can be carried over when evaluating Statement (2).
No information, variables, or constraints given in Statement (1) may carry over into the evaluation of Statement (2).
Statement (2) must be tested on its own merits as if Statement (1) did not exist.
3
Identify when statement combination is allowed.
Combining Statement (1) and Statement (2) occurs only after both Statement (1) alone and Statement (2) alone have been determined to be insufficient.
Combining prematurely leads to false sufficiency conclusions.
