GRE TC: Cause-Effect Based Questions

GRE Text Completion questions often shape meaning through a logical connection between an action and its result, or between a reason and its outcome. In cause and effect based Text Completion questions, the sentence quietly guides you by showing what triggers a situation, what follows from it, or how one idea unfolds into another. Your role is to follow this flow carefully, recognize the signals that reveal the relationship, and choose a word that completes the logic without disturbing the sentence direction. Sometimes the link appears immediately and sometimes it develops across multiple ideas, yet the core task stays consistent: understand the relationship first and let that understanding drive your choice. When you read the sentence as a sequence of linked ideas, the blank feels purposeful rather than uncertain.

The set of videos below presents cause and effect patterns in Text Completion through short, focused lessons. Each lesson shows you how to identify the source of the action, understand its outcome, and decide what the blank must communicate to keep the reasoning intact. The same approach then plays out on GRE style Text Completion examples designed to help you practice this skill in a clear and structured way. The explanation that follows the videos strengthens the same ideas. Take in the reasoning, internalize the approach, and apply it steadily while practicing GRE questions so that cause and effect relationships begin to feel natural and rewarding to work with.

Overview of Cause-Effect Based GRE TC Questions

In GRE Text Completion questions, a present participle often works as a meaning connector that explains how one idea leads to another. When a sentence includes a phrase ending in “ing,” that phrase frequently clarifies the reason behind an action or highlights the result that follows from it. Your task is to treat this phrase as a meaning guide, understand how it shapes the logic of the sentence, and then use that understanding to anticipate what belongs in the blank or blanks. This way of reading keeps the sentence coherent and purposeful rather than fragmented. The video below walks you through a clear and approachable method for spotting this pattern, shows how to interpret the role of the “ing” phrase correctly, and then applies the approach directly to GRE style Text Completion questions with carefully designed answer choices that reinforce this idea.

Understanding Cause-Effect Based Sentences | GRE TC

Many GRE Text Completion and Sentence Equivalence sentences rely on cause and effect, and these appear in about twenty five percent of the questions. You solve these sentences by identifying how one event or action directly leads to another. One idea functions as the cause, and the blank often completes the effect or reinforces that causal link.

Sentences involving cause-effect in meaning

Example

Because of its supposedly __________ properties, the blueberry has become popular among the health-conscious.

Step 1: Identify the effect Look at the second part of the sentence: “the blueberry has become popular among the health-conscious”. The “effect” is that people who care about their health are buying and eating blueberries.
Step 2: Identify the cause The sentence begins with the word “Because,” which introduces the reason for this popularity. The cause must be related to health because the people interested in the fruit are “health-conscious”.
Step 3: Evaluate the answer choices
- Healthy means conducive to or promoting good health. This fits the context because health-conscious people look for healthy things.
- Salubrious is a more formal word that also means health-giving or healthy. This also fits the context perfectly.

Step 4: Select the correct words In this specific sentence, both words provide the necessary logical link between the cause and the effect. Therefore, both words are correct choices to complete the sentence.
Final Answer: ~ healthy; a GRE-like word for ‘healthy’: ‘salubrious’

GRE-style TC Question: Cause-effect Relationship

A GRE-like TC example: Cause-effect relationship

Correct answers: protracted

For a detailed explanation of this question, please refer the last ~2 minutes of the video featured earlier on this page. Following is a step-by-step written solution:

Solution

Many historians who specialize in the study of the ancient societies assert that the gulf between the ancient and modern epochs is so ______ that the average person living today would find it impossible to fully understand the psychology of the average ancient human.

imperceivable
inconspicuous
protracted
trifling
abhorrent

1. Core Meaning

The sentence describes a cause-effect relationship. The “gulf” (gap) between ancient and modern times is so large or significant that it causes a specific effect: modern people find it “impossible” to understand ancient psychology.

2. Broad Expectation

I expect a word meaning deep, vast, or immense to describe a gap that is too wide to bridge.

3. Eliminate

- imperceivable: Impossible to perceive or notice. This is the opposite of a gap that causes a major problem.
- inconspicuous: Not clearly visible or attracting attention. Similar to imperceivable; it implies the gap is small or hidden.
- protracted: Lasting for a long time or longer than expected. While the time period is long, “protracted” usually describes events or processes, not a “gulf” or gap.
- trifling: Unimportant or trivial. If the gap were trifling, understanding ancient psychology would be easy, not impossible.
- abhorrent: Inspiring disgust and loathing. This is a moral judgment and does not logically explain why a gap makes understanding impossible.

4. Cross-check

The question likely contains a typo in its options, as none of the provided words perfectly match “vast.” However, in a GRE context, protracted is the only word that relates to the length of time separating the two eras, even if it is a secondary fit for “gulf.” If we assume the gap is defined by the “long-lasting” stretch of time, it is the only viable choice among the negatives and irrelevancies.

Correct answer: protracted

Use of Present Participle for Cause-effect Relationship | GRE TC

In this lesson, you will learn how the present participle is used to show a cause and effect relationship in a sentence. This is a very helpful tool for understanding sentence structure and logic.

Use of present participation for cause-effect relationship

What is a Present Participle?

The present participle is simply the verb + ing form of a word. Here are some common examples:

studying
eating
sleeping

How it Creates a Cause-effect Relationship

When you introduce a present participle after a comma, it generally leads to a cause and effect relationship. This means that the first action in the sentence is the reason why the second action happens.

Example 1: Action followed by effect

Scientists discovered a vaccine, putting an end to the epidemic.

Identify the cause: Scientists discovered a vaccine.
Identify the present participle: The word is “putting,” which follows a comma.
Identify the effect: The discovery of the vaccine caused the end of the epidemic.

Example 2: Effect starting with the participle

Discovering a vaccine, scientists put an end to the epidemic.

- Identify the present participle: The sentence begins with the “ing” word “Discovering”.
- Identify the cause: The act of discovering a vaccine.
- Identify the effect: Because they discovered the vaccine, the scientists were able to end the epidemic.

GRE-style TC Question: Present Participle for Cause-Effect Relationship

A GRE-like Example

Correct answers: necessitating

For a detailed explanation of this question, please refer the last ~2 minutes of the video featured earlier on this page. Following is a step-by-step written solution:

Solution

As a source of nutrition, celery is calorie-negative, since it is rich in water and cellulose – the tough, fibrous material that lines plant cells, __________ a greater expenditure of energy in its digestion than it provides the body.

procuring
manifesting
necessitating
pretending
accumulating

1. Core Meaning

The sentence defines celery as calorie-negative. This is because the plant’s tough, fibrous structure requires the body to use more energy during digestion than the celery actually provides.

2. Broad Expectation

I expect a word meaning requiring, demanding, or resulting in. The word must link the nature of cellulose to the high energy cost of digesting it.

3. Eliminate

- procuring: To obtain or get something. Celery does not “obtain” an expenditure of energy. Eliminate.
- manifesting: To show or display. While the energy use happens, this word does not capture the cause-and-effect relationship well. Eliminate.
- necessitating: To make something necessary or unavoidable. This fits perfectly because the tough material forces the body to spend energy. Keep.
- pretending: To speak or act so as to make it appear that something is the case when it is not. This is illogical in a biological context. Eliminate.
- accumulating: To gather or build up. The body is spending energy, not building it up during this process. Eliminate.

4. Cross-check

Necessitating correctly reflects the logical flow. Because cellulose is “tough” and “fibrous,” it makes a “greater expenditure of energy” a necessary requirement for digestion.

Correct answer: necessitating
