GRE Inference Questions | Critical Reasoning

Inference questions in GRE Critical Reasoning present a dense paragraph, and your task is to select the one answer choice that can be logically inferred from the information given. The correct inference is not stated directly in the paragraph. Instead, it follows clearly from the information already provided when you connect the key points in the right way. A correct inference relies only on the text and does not require assumptions, extrapolations, exaggerations, or outside knowledge.

The correct approach for solving GRE inference questions begins with building a clear mind map of the paragraph so you track the key points and their connections. You then examine each answer choice to see whether it can be deduced from the information presented in the paragraph. Eliminate any choice that requires assumptions, extrapolations, or exaggerations to be made, or that introduces a new idea or goes beyond what the paragraph supports. The following comprehensive video lesson, a part of the Experts’ Global GRE prep course, explains this question type in a structured way and demonstrates the approach on GRE-style examples. Use this resource carefully and apply the same method consistently as you continue your GRE preparation and practice for inference questions.

How Inference Questions Appear on the GRE

What do the CR Inference questions look like?

CR inference questions are based on a short paragraph, usually between 60 and 100 words, which keeps the focus clear. Each question includes a well-defined stem that guides how to think about the information presented. These stems often ask what can be logically inferred from the passage, what the author is most likely to agree with, or what must be true if the statements are true. The questions typically appear in a multiple-choice format where you select one correct answer from five options. In some cases, they ask for one or more correct answers from three options, encouraging deeper thinking. Inference-based questions often use the select-one-or-more format because a single paragraph can support multiple valid inferences. This structure helps build logical reasoning skills with clarity and confidence. Grasp this approach and apply it in your GRE drills, GRE sectional practice tests, and GRE full practice tests.

Virtues of a Valid Inference Statement

Drawing a valid inference

An inference is an idea or conclusion you draw from facts and reasoning. A valid inference builds directly on the information provided in the passage. A strong inference avoids assumption, extrapolation, and exaggeration. It includes clear reasoning that connects ideas within the passage.

A good inference goes beyond repeating a stated fact and adds meaningful insight without stepping outside the given information. The Mind Map provides structure for you to solve inference questions. Recognizing the Missing Link helps you identify traps among the answer choices and supports confident and accurate reasoning.

Strategy for Solving Inference Questions

Approach for solving CR inference questions

Identify the question as an inference task before you begin your analysis. Read the paragraph with focus on specific details and the overall structure to ensure a complete understanding of the text. You organize these ideas into a clear mind map to build a logical train of thought that connects key points. This map leads to a conclusion grounded strictly in the provided passage without the use of assumption, extrapolation, or exaggeration. You remain open to various possibilities because one paragraph often supports multiple valid inferences. To find the correct answer, you use a grid to systematically eliminate choices based only on the facts provided. This method allows you to confirm the accuracy of your selection with confidence.

Correct Answer: E

For a detailed explanation of this question, please refer to the video presented earlier on this page.

Following is a concise, step-wise written explanation, using our Missing-Link Approach (MLA)…

Step 1: Spot the Question Type

The phrase “which of the following must be true” identifies this as an Inference question. The goal is to find an option that is 100% supported by the text without making outside assumptions.

Step 2: Mind-Map the Passage

We will break the passage into three distinct bytes of information:

Byte 1: Plastic packaging produces 2 more ounces of solid pollution per pound than paper packaging.
Byte 2: Fryben Deliveries has steadily reduced the amount of plastic packaging used over the last five years.
Byte 3 (Logical Connection): If the amount of plastic (the higher pollutant) decreases, the total pollution from that specific source must also decrease.

Step 3: Avoid Assumptions

Do not assume total packaging (plastic + paper) has decreased.
Do not assume paper packaging use has increased.
Do not assume anything about the weight of deliveries or biodegradability.

Step 4: Eliminate Answer Choices

We do not know if paper packaging increased to offset the plastic reduction. Total packaging could be higher.
The passage does not provide information regarding the trend of paper packaging use.
The passage mentions solid pollution but does not define it as non-biodegradable.
We have no data on the number of deliveries or the weight of packaging used per delivery.
This is a direct logical consequence. Since plastic produces a set amount of pollution per pound, using less plastic must result in less pollution from plastic.
