1. Which of the following best describes a conclusion in an argument?

Correct Answer: Correct answer is: (A) The statement that is being argued for.

Exam Relevance: GRE, LSAT, GMAT, SAT

Difficulty: Easy

Concept notes: In an argument, the conclusion is the main point or claim that the argument is trying to establish. It is the statement that the premises are intended to support.

Common Mistakes: A common misunderstanding is to confuse the conclusion with the premises or evidence. The conclusion is the final assertion that the argument aims to prove, not the supporting details.

Explanations: The conclusion is the statement that the argument is trying to prove. It is the main point that the premises are designed to support. The other options describe different components of an argument but do not represent the conclusion itself.

Option Analysis:

Option A: This is the correct answer because the conclusion is the statement that the argument is trying to prove.
Option B: This describes the premises or evidence, not the conclusion.
Option C: This describes the logical structure, not the conclusion.
Option D: This describes the emotional appeal, not the conclusion.

2. In the statement:If you go to gym regularly and have a proper diet, you will achieve your weight goal. What is q?

Correct Answer: Correct answer is: (B) You will achieve your weight goal.

Exam Relevance: GRE, GMAT, LSAT, SAT

Difficulty: Easy

Concept notes: In logical statements, the conclusion is the part that follows from the premises. Here, the conclusion is "You will achieve your weight goal."

Common Mistakes: A common mistake is to confuse the premise with the conclusion. The premise is the condition that leads to the conclusion, not the conclusion itself.

Explanations: The statement "If you go to gym regularly and have a proper diet, you will achieve your weight goal" is a conditional statement. In such statements, the part that follows "if" is the premise, and the part that follows "you will" is the conclusion. Therefore, "You will achieve your weight goal" is the conclusion.

Option Analysis:

Option A: This is the premise of the statement, not the conclusion.
Option B: This is the conclusion of the statement.

3. Describe the significance of a conclusion in an argument.

Correct Answer: Correct answer is: (B) The conclusion in an argument is significant as it summarizes the main points and provides a final decision or resolution based on the evidence presented.

Exam Relevance: GRE, LSAT, GMAT, SAT

Difficulty: Moderate

Concept notes: The conclusion in an argument is crucial as it ties together the main points and provides a final resolution or decision based on the evidence presented.

Common Mistakes: A common misunderstanding is that the conclusion is merely a restatement of the introduction or a weak part of the argument.

Explanations: The conclusion in an argument is significant because it serves to summarize the main points and provide a final decision or resolution based on the evidence presented. It is not irrelevant or weak, nor is it solely a restatement of the writer's opinion. Instead, it synthesizes the evidence and arguments to reach a logical and coherent conclusion.

Option Analysis:

Option A: This option is incorrect because the conclusion is not irrelevant and cannot be omitted without losing the argument's coherence and finality.
Option B: This option is correct because the conclusion is significant as it summarizes the main points and provides a final decision or resolution based on the evidence presented.
Option C: This option is incorrect because the conclusion is not always the weakest part of an argument; it is often the most critical part.
Option D: This option is incorrect because the conclusion is important regardless of whether it supports the writer's opinion or not; it must be based on the evidence presented.

4. What is the conclusion of the following statement? If it rains, the ground will be wet. It is raining.

Correct Answer: Correct answer is: (B) The ground is wet.

Exam Relevance: GRE, GMAT, LSAT, SAT

Difficulty: Easy

Concept notes: The question involves a conditional statement and its logical conclusion. The statement "If it rains, the ground will be wet" sets up a condition where rain leads to a wet ground. Given that it is raining, the conclusion logically follows that the ground will be wet.

Common Mistakes: A common mistake is to assume that the ground might not be wet even if it is raining, possibly due to other factors like a covered area or a very short duration of rain. However, the statement does not account for such exceptions, so the logical conclusion must be based solely on the given condition.

Explanations: The statement "If it rains, the ground will be wet" establishes a direct relationship between rain and a wet ground. Since it is given that it is raining, the logical conclusion is that the ground is wet.

Option Analysis:

Option A: This is incorrect because the statement directly implies that rain leads to a wet ground.
Option B: This is correct because the statement "If it rains, the ground will be wet" and the fact that it is raining logically lead to the conclusion that the ground is wet.
Option C: This is incorrect because the statement does not provide any information about whether it is raining or not; it is given that it is raining.
Option D: This is incorrect because the statement does not provide any information about future rain; it is given that it is currently raining.

5. What is the conclusion of the following statement: "The angles are supplementary, if they add up to 180 degrees."

Correct Answer: Correct answer is: (B) The angles are supplementary.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Easy

Concept notes: In a conditional statement, the conclusion is the part that follows "if" and is the result of the condition being met.

Common Mistakes: A common mistake is to confuse the hypothesis (the "if" part) with the conclusion. The hypothesis is the condition that must be met, while the conclusion is the result of that condition.

Explanations: The statement "The angles are supplementary, if they add up to 180 degrees" is a conditional statement. In such statements, the part that follows "if" is the hypothesis, and the part that follows the comma is the conclusion. Here, "The angles are supplementary" is the conclusion because it is the result of the condition "they add up to 180 degrees."

Option Analysis:

Option A: This is the hypothesis, not the conclusion.
Option B: This is the correct conclusion of the statement.
Option C: This is the hypothesis, not the conclusion.
Option D: This is incorrect as there is a clear conclusion in the statement.

6. The "then" part of the conditional statement is called the .....

Correct Answer: Correct answer is: (A) Conclusion.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Easy

Concept notes: In a conditional statement, the "then" part is known as the conclusion.

Common Mistakes: A common mistake is confusing the "then" part with the hypothesis, which is the "if" part of the statement.

Explanations: In a conditional statement, the structure is typically "if [hypothesis], then [conclusion]." The "then" part directly follows the hypothesis and represents the result or outcome of the hypothesis being true. Therefore, the "then" part is called the conclusion.

Option Analysis:

Option A: Correct. The "then" part of a conditional statement is the conclusion.
Option B: Incorrect. The hypothesis is the "if" part of the statement.
Option C: Incorrect. The entire "if-then" structure is the conditional statement.
Option D: Incorrect. A conjecture is an unproven proposition or theory, not a part of a conditional statement.

7. What is the author's claim in this argument: "School uniforms improve focus because they remove distractions caused by clothing choice s" ?

Correct Answer: Correct answer is: (B) School uniforms improve focus.

Exam Relevance: GRE, LSAT, GMAT, SAT

Difficulty: Easy

Concept notes: The claim in the argument is the main point the author is trying to convey. In this case, the author is asserting that school uniforms improve focus.

Common Mistakes: A common mistake is to confuse the claim with supporting evidence or a related idea. For example, one might incorrectly identify "clothing choices create distractions" as the claim, when it is actually a supporting detail.

Explanations: The author's claim is that school uniforms improve focus. This is the main point being argued, and the rest of the statement provides a reason for this claim, which is that uniforms remove distractions caused by clothing choices.

Option Analysis:

Option A: This is not the claim; it is a potential counter-argument.
Option B: This is the claim, as it directly states the main point of the argument.
Option C: This is a supporting detail, not the main claim.
Option D: This is not mentioned in the argument and is unrelated to the claim.

8. What completes an argument?

Correct Answer: Correct answer is: (C) A conclusion.

Exam Relevance: GRE, LSAT, GMAT

Difficulty: Moderate

Concept notes: A conclusion is the final part of an argument that summarizes the main points and restates the claim in light of the evidence presented. It provides closure to the argument and reinforces the author's position.

Common Mistakes: A common misunderstanding is that an argument ends after presenting the last piece of evidence, but a conclusion is necessary to tie the argument together and provide a clear ending.

Explanations: A conclusion completes an argument by summarizing the key points and restating the claim in a way that reflects the evidence provided. It helps to reinforce the author's position and provides a clear and coherent ending to the argument.

Option Analysis:

Option A: Restating the claim alone does not complete an argument; it lacks the synthesis and closure provided by a conclusion.
Option B: How an author really feels is not a formal component of completing an argument; it may be part of the argument but does not serve as a conclusion.
Option C: A conclusion is the correct answer because it ties together the argument, summarizes the evidence, and restates the claim in a way that provides closure.
Option D: An argument does not end after the last piece of evidence; a conclusion is necessary to provide a coherent and complete argument.

9. The central point of an argument is called the .....

Correct Answer: Correct answer is: (B) Conclusion.

Exam Relevance: GRE, LSAT, GMAT, Critical Reasoning exams

Difficulty: Easy

Concept notes: In an argument, the central point or main idea that the argument aims to support is called the conclusion.

Common Mistakes: A common misunderstanding is confusing the conclusion with the premises, which are the supporting statements that lead to the conclusion.

Explanations: The conclusion is the central point of an argument. It is the main claim or assertion that the argument is trying to prove or support. The premises provide the evidence or reasons that lead to the conclusion. Therefore, the central point of an argument is the conclusion.

Option Analysis:

Option A: A premise is a supporting statement that leads to the conclusion, not the central point of the argument.
Option B: The conclusion is the central point of the argument, which the premises aim to support.
Option C: An argument is the entire structure that includes both the premises and the conclusion, not just the central point.
Option D: This option is incorrect as the conclusion is the correct term for the central point of an argument.

10. "A proposition that is reached from given premises."

Correct Answer: Correct answer is: (B) Conclusion.

Exam Relevance: GRE, LSAT, GMAT, SAT

Difficulty: Easy

Concept notes: A conclusion is the proposition that is derived from given premises in a logical argument.

Common Mistakes: A common misunderstanding is confusing a conclusion with a premise. A premise is a statement that provides support for the conclusion, whereas the conclusion is the result of the logical reasoning based on the premises.

Explanations: In a logical argument, the conclusion is the statement that is reached based on the given premises. It is the final proposition that follows logically from the premises. Therefore, the correct answer is "Conclusion."

Option Analysis:

Option A: A premise is a statement that provides support for the conclusion, not the conclusion itself.
Option B: A conclusion is the proposition that is reached from given premises, which matches the definition provided in the question.
Option C: "Valid" refers to the logical structure of an argument, not the conclusion itself.
Option D: "Sound" refers to an argument that is both valid and has true premises, not the conclusion itself.
