3.2 Two-Part Analysis

Introduction to Two-Part Analysis

Two-Part Analysis (TPA) is perhaps the most versatile and unique question type on the Executive Assessment. These questions can be heavily quantitative, purely verbal, or a complex hybrid of both disciplines. The defining feature of a TPA question is its unique format: you are presented with a single scenario or problem, followed by a question that asks you to determine two distinct but related pieces of information. Your answers are selected from a single, unified list of options presented in a two-column table.

Because the two answers are almost always interdependent, TPA questions test your ability to track multiple variables simultaneously and understand the logical or mathematical relationship between them. Like all Integrated Reasoning questions, there is no partial credit on the Executive Assessment; you must select the correct answer in both columns to earn the point for the question.

The Two-Part Analysis Format

The interface for a Two-Part Analysis question consists of a text prompt—sometimes accompanied by a brief table, a short set of rules, or an algebraic equation—and a unique answer grid.

The grid contains:

• Column 1: Represents the first task or variable you need to identify (e.g., "Company A's Profit," "Assumption," "Numerator").
• Column 2: Represents the second task or variable (e.g., "Company B's Profit," "Conclusion," "Denominator").
• Rows: A shared list of 5-6 possible answer choices.

You must select exactly one bubble in Column 1 and exactly one bubble in Column 2. It is mathematically possible, depending entirely on the nature of the specific question, for the same row to be the correct answer for both columns, though this is relatively rare.

Solving Quantitative TPA Tasks

Quantitative TPA questions often test algebra, word problems, statistics, and financial math, but with an added layer of complexity because you are solving for two interconnected variables at once rather than a single solution.

Common quantitative scenarios include:

• Simultaneous Equations: The prompt provides a word problem that translates into a system of two algebraic equations. You must solve for both variables (e.g., the price of a widget and the price of a gadget).
• Ratios and Proportions: You are given the ratio of mixtures, ingredients, or population demographics and must determine the actual quantities involved or a new ratio after a specific change is applied.
• Rate Trade-offs: Problems involving distance, rate, and time, or collaborative work rates, where changing one variable directly affects the outcome of another.
• Financial Metrics: Calculating interconnected business metrics like Revenue, Cost, and Profit, where determining the answer for Column 1 provides the missing numerical piece needed to calculate Column 2.

Strategy for Quant TPAs:

1. Translate to Algebra: Immediately convert the text of the prompt into algebraic equations on your scratchpad.
2. Isolate and Substitute: If the variables are interdependent, isolate one variable and substitute it into the second equation to solve the system.
3. Test the Answers (Backsolving): Because the final answers are provided in the list, you can often plug the numbers directly back into the constraints of the prompt. If you pick a number for Column 1, does it yield a valid number in Column 2 that is also available in the answer choices? If not, your initial choice is wrong.

Solving Verbal and Logical TPA Tasks

Verbal TPA questions require you to analyze arguments, evaluate logical structures, or follow complex rule sets. They are essentially advanced, multi-step Critical Reasoning questions.

Common verbal scenarios include:

• Assumption and Conclusion: You are given an argument and must identify both an underlying unstated assumption (Column 1) and a logical, supported conclusion (Column 2).
• Cause and Effect: The prompt describes a complex phenomenon or chain of events, and you must identify the primary catalyst or cause and the ultimate resulting effect from the list of options.
• Compatible Roles: You are given a strict set of constraints (e.g., scheduling a meeting across time zones, assigning project roles based on skill sets) and must find two individuals or times that satisfy all rules simultaneously without generating a conflict.
• Strengthen and Weaken: Identifying one statement that reinforces an argument and another statement that undermines it.

Strategy for Verbal TPAs:

1. Read the Column Headers First: Before reading the prompt, look directly at the column headers. Knowing that you are looking for a "Cause" and an "Effect" fundamentally changes how you read the text, allowing you to filter out irrelevant background information.
2. Deconstruct the Argument: Identify the core premise, the conclusion, and the logical gap between them.
3. Evaluate Independently, then Together: Find a strong candidate for Column 1. Then, ask yourself: "If this is the answer for Column 1, does my choice for Column 2 still make logical sense within the same framework?"

Managing Inter-Dependent Variable Constraints

The defining challenge of Two-Part Analysis is interdependence. Often, you absolutely cannot solve for Column 2 without first solving for Column 1, or the relationship between the two columns is the entire key to unlocking the problem.

Consider this simplified quantitative example: Prompt: A small business sells standard and premium subscriptions. The total number of subscriptions sold in Q1 is 100. The business generated exactly $1,500 in total revenue. Standard subscriptions cost $10 each, and premium subscriptions cost $20 each. Question: Determine the exact number of standard subscriptions (Column 1) and premium subscriptions (Column 2) sold.

Step 1: Translate to equations. Let S = standard subscriptions, P = premium subscriptions. Equation 1 (Total Volume): S + P = 100 Equation 2 (Total Revenue): 10S + 20P = 1500

Step 2: Solve the system using substitution. From Equation 1: S = 100 - P Substitute this into Equation 2: 10(100 - P) + 20P = 1500 1000 - 10P + 20P = 1500 10P = 500 P = 50 (Premium subscriptions)

Step 3: Find the dependent variable. If P = 50, then returning to Equation 1: S = 100 - 50 = 50.

In the answer grid, you would select the row indicating "50" in both Column 1 and Column 2.

Common Pitfalls in Two-Part Analysis

1. Column Confusion: The most tragic and frustrating error in TPA is solving the mathematical or logical problem perfectly, but bubbling the answers in the wrong columns (e.g., bubbling the "Premium" quantity in the "Standard" column). Always take five seconds to double-check the column headers before finalizing your choice.
2. Ignoring Constraints: Missing a key modifier word like "integer," "positive," "consecutive," or "mutually exclusive" in the prompt can lead you to an incorrect pair of answers that mathematically works but violates the specific rules of the scenario.
3. Over-Calculating: In quantitative TPAs, candidates sometimes spend three minutes calculating complex fractional values when estimating or testing the provided answer choices would yield the correct pair in thirty seconds.

Mastering Two-Part Analysis requires mental agility and flexibility. You must be prepared to seamlessly shift from solving a system of linear equations in one question to untangling a philosophical argument in the next, all while carefully managing the interdependent nature of the two-column grid.
