Difficulty: MediumValue vs. Yes/No Data Sufficiency Decision Logic

In a GMAT Data Sufficiency 'Value' question asking for the specific numerical value of a variable xx, a statement that narrows xx down to exactly two distinct numerical solutions provides sufficient information.

Answer: Answer

Answer

False
The statement is False. GMAT Data Sufficiency questions are divided into two structural categories: Value questions and Yes/No questions. For a 'Value' question, a statement is sufficient only if it allows you to determine one single, unambiguous numerical value. If a statement results in two or more distinct possible values, the exact value of the target cannot be determined, so the statement is insufficient.

Step-by-Step Solution

1
Identify the standard for sufficiency in a GMAT Data Sufficiency 'Value' question.
A statement must produce a single, unique numerical value for the target variable or expression.
Value questions require determinacy; if more than one value is possible from the statement alone, the specific value is unknown.
2
Evaluate the condition where a statement yields exactly two distinct numerical solutions.
Since two distinct values exist, the statement fails to provide a unique value, rendering it insufficient.
Having a finite set of two solutions (e.g., x=2x = 2 or x=−2x = -2) does not satisfy the unique value requirement of Value Data Sufficiency questions.
