GMAT Multi Source Reasoning

Multi-Source Reasoning questions begin with two or three sources of information, each labelled with a tab, which appear on the left side of a split computer screen. One or more of the sources will contain a written passage. The other sources may be tables, graphs, diagrams, or other types of visual information. Only one source of information will be displayed at a time. To view a different source, select its tab from those that appear above the source currently displayed.

The sources of information are accompanied by questions that will ask you to synthesize, compare, interpret, or apply the information presented. As each question associated with the sources appears in turn on the right side of the screen, the initial source will appear again on the left side. You can click on the tabs to view any of the sources as many times as needed. However, you will see only one question at a time and cannot go back to earlier questions.

Question Formats

There are two question formats for Multi-Source Reasoning:

  1. Multiple-choice questions
  2. Multiple-dichotomous choice questions

For multiple-choice questions, select the best of the five answer choices given. 

Multiple-dichotomous choice questions provide three phrases, statements, numerical values, or algebraic expressions that require an indication as to whether each meets a certain condition. For example, you may be asked whether

  • Each statement is true, according to the sources
  • Each statement or numerical value is consistent with the sources
  • Each statement or algebraic expression would solve a problem described in the sources
  • Value of each algebraic expression can be determined on the basis of the sources


The multi-source reasoning questions appear in one of two formats: three part table (similar to table-analysis questions) or standard five-answer multiple-choice. You have to answer all three parts of the first format to get credit for the one question.
