Data Insights: Multi-Source Reasoning Flashcards

In a GMAT Multi-Source Reasoning prompt, sources are typically arranged across two or three tabs. What is the most efficient first step before answering?

Answer: Skim all tabs to map what each contains, then return as questions demand

Mapping the content of each tab first lets you locate and combine the right data quickly for each question.

An MSR set shows an email (Tab 1) and a budget table (Tab 2). A question asks whether a proposed expense is approvable. Which approach is correct?

Answer: Combine the email's approval rule with the table's figures

MSR rewards synthesizing a rule from one source with quantitative data from another.

MSR yes/no (Inference) questions usually present three statements. How are they scored?

Answer: All three must be answered correctly for the item to count

These multi-part items award credit only when all sub-statements are answered correctly.

A tab states a project starts on March 1 and lasts 6 weeks; another tab lists a hard deadline of April 10. Can the project finish on time?

Answer: No, it runs past April 10

Six weeks (42 days) from March 1 reaches roughly April 12, which is after the April 10 deadline.

When an MSR question gives a condition not directly stated in any tab, what should you do?

Answer: Apply the new condition to the existing data to test the outcome

Hypothetical conditions must be applied logically to the provided data, not found word-for-word.

Two tabs report a metric using different units (one in thousands, one in actual dollars). Before comparing, you must:

Answer: Convert to a common unit

Unit mismatches are a common MSR trap—always reconcile units before computing.

Which behavior best describes effective MSR time management?

Answer: Reading the question first, then targeting the relevant tab(s)

Question-driven reading keeps you from over-investing time in irrelevant source details.
