GMAT Two Part Analysis : (TPA) Questions
Archaeologists excavating an ancient Chi-Xua site found a small statue along with white-and-red striped pottery fragments and small bits of cloth in a one-room building approximately 6 meters by 5 meters. The building had a single entrance, opening to a narrow exterior porch. The building's walls were made of local sandstone.
Select the proposition that, if true, would provide the strongest evidence For the hypothesis that the room had a residential function and select the proposition that, if true, would provide the strongest evidence Against the hypothesis. Make only two selections, one in each column.

Argument Structure
- Main hypothesis: The room had a residential function
- Supporting evidence: Contains various artifacts (statue, pottery, cloth)
- Physical characteristics: One room, single entrance, porch, sandstone walls
- What we need to determine: Which facts support or oppose residential use
Phase 2: Question Analysis & Prethinking
Understanding What Each Part Asks
- Part 1 (For): What evidence would most strongly suggest this was someone's home?
- Part 2 (Against): What evidence would most strongly suggest this was NOT someone's home?
- Relationship: We need to find the strongest evidence on both sides of the residential hypothesis
Prethinking for Each Part
For residential function, we'd want evidence showing:
- Daily living activities (cooking, eating, sleeping)
- Personal belongings
- Domestic artifacts
- Layout suitable for living
Against residential function, we'd want evidence showing:
- The building served another purpose (ceremonial, storage, commercial)
- Characteristics inconsistent with Chi-Xua residential patterns
- Artifacts suggesting non-residential use
Phase 3: Answer Choice Evaluation
Evaluating Each Choice
Choice 1: "Local sandstone was rarely used for building in ancient Chi-Xua sites."
- This makes the building unusual but doesn't specifically indicate residential vs. non-residential
- For residential: Weak (doesn't support)
- Against residential: Weak (unusual material doesn't mean non-residential)
Choice 2: "Nearly all Chi-Xua residential buildings had multiple rooms."
- This building has only ONE room
- If residential buildings typically had multiple rooms, this single-room structure likely isn't residential
- For residential: Doesn't support
- Against residential: VERY STRONG - directly contradicts typical residential pattern
Choice 3: "Some Chi-Xua buildings included multiple storage rooms measuring approximately 30 square meters."
- This building is 30 square meters total
- Mentions storage rooms, not particularly relevant to residential function
- For residential: Weak
- Against residential: Weak
Choice 4: "The cloth fragments did not contain the pigments commonly used in Chi-Xua ceremonial robes."
- Suggests the cloth was ordinary, not ceremonial
- Everyday cloth = more likely residential
- For residential: Moderate support (rules out ceremonial use)
- Against residential: Doesn't support
Choice 5: "Red-and-white striped pottery was used in Chi-Xua almost exclusively for personal food storage."
- Personal food storage = strong indicator of residential use
- People store food where they live
- For residential: VERY STRONG - directly indicates domestic activity
- Against residential: Doesn't support
The Correct Answers
For Part 1 (For residential): Choice 5 - The pottery being used "almost exclusively for personal food storage" provides the strongest evidence that this was a residence. Personal food storage is a quintessential residential activity.
For Part 2 (Against residential): Choice 2 - The fact that "nearly all Chi-Xua residential buildings had multiple rooms" while this building has only one room provides the strongest evidence against residential function. It shows this building doesn't match the typical residential pattern.
Common Traps to Highlight
Choice 4 might seem like good evidence FOR residential function since it rules out ceremonial use. However, it's weaker than Choice 5 because:
- It only tells us what the building wasn't (ceremonial)
- It doesn't positively indicate residential use
- Choice 5 directly points to a residential activity (personal food storage)
Choice 1 might seem like evidence AGAINST any typical function, but:
- Unusual building material doesn't specifically oppose residential use
- It could make any type of building unusual, not just residential ones
- Choice 2 specifically contradicts residential patterns, making it much stronger
