GRE RC: How to Solve Inference-Based Questions

The video below and the theory that follows give you a focused recap of our Mind Map Approach for attempting RC, show you how to apply it to inference-based GRE Reading Comprehension questions, and then demonstrate its use on GRE-style questions with representative answer choices so you gain direct experience with the method. Take your time, pause the video to apply the approach on your own, study each explanation carefully, and by the end, develop a clear habit of using the Mind Map Approach for inference-based Reading Comprehension across your GRE drills, GRE sectional tests, and GRE full tests.

Recap of the Mind Map Approach for RC

In a previous lesson, we learnt the Mind Map Approach for handling GRE Reading Comprehension questions, and this lesson builds smoothly on that learning. As a part of our GRE preparation course, the Mind Map Approach has supported tens of thousands of students worldwide since 2008. With clear understanding and steady practice, this approach helps you engage with GRE Reading Comprehension in a structured way that supports both accuracy and pace.

Summary: Mind Map Approach (MMA) for attempting all GRE RCs

Before moving ahead, here is a brief refresh of the Mind Map Approach –

Begin by skimming the first byte of the passage, which means one logical unit you can grasp in a single look, without entering details. Ask yourself what this byte does and keep the takeaway short. Move to the next byte, ask the same question, and keep that takeaway short as well. Link the takeaways as you move forward and repeat this process for each new byte to create a clear mental map of the passage. After that, read the question and use a grid to remove incorrect answer choices and each the correct one.

Using the Mind Map Approach for Solving Inference Based GRE RC Questions

The 3 broad categories of GRE RC questions

GRE Reading Comprehension questions broadly fall into three types: structure-based, fact-based, and inference-based. The Mind Map Approach supports all three. In this lesson, the focus is on applying the Mind Map Approach to inference-based Reading Comprehension questions. These questions require you to go beyond what is directly stated and draw deductions that logically follow from the passage. The mind map you build helps you track ideas, relationships, and progression in the passage, while also making it clear where specific information sits, so you know exactly which part of the passage to return to when drawing inferences that stay fully supported by the text, without drifting away from what the text supports.

GRE-Style Inference-Based RC Practice Question

Below is a snapshot of the GRE style Inference based Reading Comprehension question discussed in the video, along with the Mind Map approach used to solve it and the Mind Map created for the passage.

GRE RC question

Correct Answer: E

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

Following is a step-wise written explanation, using our Mind Map Approach…

Step 1 and 2: First Byte

Byte: “Can we consider Carl Sagan a remarkable scientist? One’s immediate reaction may be to dismiss this question as superfluous.”
- What it did: It raised a question regarding Carl Sagan’s status as a scientist.

Step 3 and 4: Subsequent Bytes

Second Byte: “A gifted astronomer… key role… search for extraterrestrial life… widely recognized… advocate for science education.”
- What it did: It developed a case for YES by highlighting his accomplishments and fame.
Third Byte: “However… incongruent with his standing among scientists… unwilling to group him alongside… Ghez or Drake… liaison between the sciences.”
- What it did: It developed a case for NO by noting that other scientists are hesitant to rank him as a top specialist.

Step 5: Read the Question

Question: It can be inferred that the “unwillingness” mentioned in the passage is on the part of…

Step 6: Eliminate

the general public (Eliminate: The text says his gifts were “widely recognized,” implying the public liked him, but his “standing among scientists” was the issue).
most astronomers since Sagan (Eliminate: The passage does not specify a timeline or include all astronomers after him).
only Kuiper (Eliminate: Kuiper is used as an example to explain the sentiment, but the text implies a broader “standing among scientists”).
Ghez and Drake (Eliminate: These are names of scientists he is being compared to, not necessarily the people feeling the unwillingness).
scientists in general (Keep: The passage explicitly links this “unwillingness” to his “standing among scientists”).
