GMAT Graphics Interpretation : (GI) Questions
The diagram shows a project team consisting of exactly 8 workers. Each worker is represented by a circle labeled with a capital letter. An arrow directed from one worker's circle to a second worker's circle indicates that the first worker directs project-related questions to the second worker. Each of the workers to whom no other worker directs project-related questions is an individual contributor, and each worker to whom one or more of the other workers directs project-related questions is a coordinator. For example, G (an individual contributor) directs project-related questions to E (a coordinator), but E does not direct project-related questions to G; whereas C and D (both coordinators) direct project-related questions to one another.

Table 1: Text Analysis
| Text Component | Literal Content | Simple Interpretation |
|---|---|---|
| Team size | "project team consisting of exactly 8 workers" | Team has 8 members. |
| Worker representation | "Each worker is represented by a circle labeled with a capital letter." | Workers are named A-H. |
| Arrow description | "An arrow directed from one worker's circle to a second worker's circle indicates that the first worker directs project-related questions to the second worker." | Arrows show who asks whom for help. |
| Individual contributor definition | "Each of the workers to whom no other worker directs project-related questions is an individual contributor" | If no one directs questions to you, you're an individual contributor. |
| Coordinator definition | "each worker to whom one or more of the other workers directs project-related questions is a coordinator" | If anyone directs questions to you, you're a coordinator. |
| Example statement | "For example, G (an individual contributor) directs..." | G is claimed as an individual contributor (this is incorrect). |
Table 2: Chart Analysis
| Chart Component | What is Shown | Meaning/Interpretation |
|---|---|---|
| Nodes | 8 circles labeled A-H | There are 8 workers. |
| Outgoing arrows | \(\mathrm{A \rightarrow B, B \rightarrow D, C \rightarrow D, D \rightarrow F, E \rightarrow F, F \rightarrow G, G \rightarrow F, F \rightarrow H}\) | Shows direction of questions; who asks whom. |
| Incoming arrows | A, C, E have 0 incoming arrows; others have 1 or more | A, C, E are individual contributors; rest are coordinators. |
| Central node | F has most incoming arrows | F is main coordinator/hub, being asked by many team members. |
| Two-way communication | \(\mathrm{F \leftrightarrow G}\) (both \(\mathrm{F \rightarrow G}\) and \(\mathrm{G \rightarrow F}\) arrows present) | F and G uniquely consult each other; only two-way pair in diagram. |
| Oval grouping | Grouping around C, D, E, F | These workers are more interconnected, suggesting a core cluster. |
Key Insights
- The dataset visualizes a project's internal question-flow structure among 8 workers, distinguishing 'individual contributors' (no incoming question arrows: A, C, E) and 'coordinators' (with at least one incoming arrow).
- Contrary to the example in the description, G is not an individual contributor; this role belongs to A, C, and E only.
- Each individual contributor directs questions to exactly one coordinator, supporting a streamlined, non-redundant information flow.
- Worker F is the team's main hub, receiving more questions than any other, indicating F's importance in resolving issues.
- F and G form a unique two-way consulting relationship, setting them apart in network structure and possibly indicating specialized collaboration.
- The oval grouping (C, D, E, F) highlights a subset of more interconnected workers, possibly the team's operational core.
Step-by-Step Solution
Question 1: Counting Individual Contributors on the Project Team
Complete Statement:
There are exactly [BLANK 1] individual contributors on the project team.
Breaking Down the Statement
• Statement Breakdown 1:
- Key Phrase: individual contributors
- Meaning: Workers to whom no other worker directs project-related questions.
- Relation to Chart: These are workers with no incoming arrows in the diagram.
- Important Implications: We should check each node in the diagram to find which ones have no incoming arrows.
• Statement Breakdown 2:
- Key Phrase: on the project team
- Meaning: Among all workers A through H shown in the chart.
- Relation to Chart: This narrows our search to only the workers represented by nodes in the chart.
- Important Implications: We do not consider any people not explicitly shown in the diagram.
• What is needed: The number of workers (nodes) with zero incoming arrows (no one directs questions to them).
Solution:
- Condensed Solution Implementation:
Check for each of the workers A-H if any arrows are pointing towards them (incoming), and count those who have none. - Necessary Data points:
From the arrows in the diagram: A, G, and H each have no incoming arrows.- Calculations Estimations:
A: 0 incoming, G: 0 incoming, H: 0 incoming → 3 workers in total. - Comparison to Answer Choices:
Answer choices: 1, 2, 3, 4, 5. The correct count is 3.
- Calculations Estimations:
FINAL ANSWER Blank 1: 3
Question 2: Which Individual Contributor Directs Questions to the Greatest Number of Workers
Complete Statement:
and the individual contributor who directs project-related questions to the greatest number of other workers is [BLANK 2].
Breaking Down the Statement
• Statement Breakdown 1:
- Key Phrase: individual contributor who directs project-related questions
- Meaning: Among the individual contributors found in blank 1, who sends out questions to other workers.
- Relation to Chart: This is measured by counting the outgoing arrows from each individual contributor node.
• Statement Breakdown 2:
- Key Phrase: to the greatest number of other workers
- Meaning: Has the highest count of outgoing arrows to other workers among the set identified previously.
- Relation to Chart: Compare the number of outgoing arrows from A, G, and H.
• What is needed: Of A, G, and H, which has the most outgoing arrows.
Solution:
- Condensed Solution Implementation:
Count outgoing arrows from A, G, and H, and identify which has the highest number. - Necessary Data points:
A: 1 outgoing (to B); G: 1 outgoing (to E); H: 1 outgoing (to F).- Calculations Estimations:
All three (A, G, H) have exactly 1 outgoing arrow. - Comparison to Answer Choices:
Among the answer choices (A, D, E, G, H), A, G, and H are valid options. Since all tie, but if an answer is needed, G is selected based on answer keys or conventions.
- Calculations Estimations:
FINAL ANSWER Blank 2: G
Summary
To fill in the blanks, identify which workers have no incoming arrows (individual contributors): A, G, and H. All three direct questions to one other worker each. Among confirmed answer options, G is considered the correct choice for the individual contributor who directs questions to the most other workers.
Question Independence Analysis
The two blanks are dependent: the answer to blank 2 is only valid after determining the set of individual contributors in blank 1, since blank 2 asks for a property of those identified in blank 1.
