Lesson 7.4: Efficiency Strategy for Parallel Questions

Introduction

In this lesson, we will explore efficient strategies for tackling parallel reasoning questions on the LSAT. These questions require you to identify a conclusion that mirrors the logic of a given argument, regardless of the topic or subject matter involved. We will focus on how to triage, eliminate, and effectively manage your time when faced with such questions. By the end of this lesson, you will be equipped to handle parallel reasoning questions quickly and effectively, ensuring that you maintain a pace throughout the LSAT section.

Objectives

• Understand triage and elimination order to control time on long parallel sets.
• Make decisions about when to skip and return to a parallel question.
• Apply a fast elimination sequence to parallel questions.
• Make sound skip-and-return decisions to protect section pacing.
• Explain the main ideas and terminology behind Efficiency Strategy for Parallel Questions.

Understanding Parallel Reasoning Questions

What is Parallel Reasoning?

Parallel reasoning questions require you to look beyond the content of an argument and analyze its structure. The goal is to find an answer choice that reflects the same logical pattern. This often involves identifying flawed reasoning or drawing conclusions in a manner consistent with the argument presented in the stimulus.

Example of Parallel Reasoning

Consider the following argument:

1. Stimulus: Most birds can fly. Penguins are birds. Therefore, penguins can fly.

This argument is logically flawed because it makes an inaccurate assumption about a specific subset.

1. Correct Structure Identification:

To find a parallel reasoning question, we identify the flaw and conclusion:

• Major premise: Most X (birds) have characteristic Y (can fly).
• Minor premise: Z (penguin) is an X (bird).
• Flaw: Incorrectly applies Y to Z.

When faced with answer choices, we look for one that uses the same logical structure, even if the subjects are different.

Strategies for Triage and Elimination

Time Management Techniques

When confronted with a set of parallel reasoning questions, it is crucial to manage your time wisely. You could encounter lengthy passages; hence, efficient triage will be vital. Here, we discuss various strategies:

1. Prioritize Questions: Quickly read each question and determine if you can logically solve it at that moment. If it seems too complex or time-consuming, mark it and move on, planning to return if time permits.

1. Eliminate Distractors: As you consider an answer, quickly rule out choices that clearly do not share the same structure or logical flaws as the stimulus. For example, if the stimulus deals with birds, eliminate answers referring to unrelated subjects like plants or vehicles.

Worked Example

Let’s analyze a practical example regarding effective elimination:

• Stimulus: “All artists are creative. Some athletes are not creative. Therefore, some athletes are not artists.”

When searching for a parallel reasoning question, imagine the choices given:

1. All musicians are artists. Thus, no musicians are athletes.
2. Some dancers are not aggressive. Therefore, some aggressive individuals are not dancers.
3. All designers are innovative, while some engineers are not innovative. Therefore, some engineers cannot be designers.

Analysis of Options:

• Option 1 introduces a completely new structure that does not align with the stimulus.
• Option 2 presents a new conclusion without mirroring the structure we are seeking.
• Option 3, however, maintains the proper logical structure of drawing improper conclusions from a subset.

Thus, we can conclude option 3 parallels the reasoning used in the stimulus and would be the correct answer.

Determining When to Skip Questions

One critical efficiency strategy is understanding when to skip a question. Here’s how you can make informed decisions about when to return to a question:

1. Under Time Pressure: If you have only a few minutes left and you've spent more than one minute on a question without substantial progress, mark it and move on. Prioritize ensuring you can answer as many questions as possible.
2. Recognizing Complexity: If the structure of an argument is convoluted or if the answer choices are significantly complex, don’t hesitate to skip it initially. The time you save here can be utilized on questions you can answer with clarity.

Example of Skip Decision

For instance, if you encounter this complex reasoning:

• Stimulus: In some regions, the water is abundant, yet crop failures occur because of poor irrigation. Thus, high water doesn’t guarantee high crop yields.

If the answer choices are similarly abstract, and time is running out, it makes sense to defer this question and conduct quick analyses for others.

Quick Elimination Sequence for Parallel Questions

Here's a fast method for eliminating choices that might not parallel the reasoning structure:

1. Check the Conclusion First: Read the conclusion of each answer choice immediately. If the conclusion is incorrect or unrelated, eliminate it.
2. Identify Flaw: Determine quickly if the reasoning follows logically or if it contains flawed reasoning similar to the original argument. Eliminate any that do not follow.
3. Parallels in Structure: Finally, ensure that any remaining choices mirror the structure and flaw of the original argument before making your selection.

Example of Quick Elimination

Let’s say your original argument centers on economic stability leading to happiness:

• Stimulus: A stable economy leads to better living conditions, which results in increased happiness.

Possible answer choices:

1. A healthy lifestyle leads to happiness exclusively.
2. Sustained economic growth results in greater job satisfaction.
3. Stable environments lead to living conditions favorable for health, hence improved well-being.

Elimination Process:

• Option 1 does not correlate logically with the stimulus.
• Option 2 introduces a valid point; however, it doesn’t present a complete parallel structure.
• Option 3 correctly mirrors the structure, making it the strongest choice.

Conclusion

Efficiency strategies for parallel reasoning questions hinge on your ability to manage time effectively and make quick eliminations. By recognizing when to skip questions and understanding how to analyze the structure of arguments critically, you will become adept at handling even the most challenging parallel reasoning questions presented on the LSAT. This skill not only boosts your confidence but also your overall performance on the exam.

Study Notes

• Parallel reasoning questions focus on the structure, not content.
• Employ triage techniques to prioritize time management.
• Eliminate distractors by checking conclusion relevance.
• Skip complex questions under time pressure and return if time permits.
• Use a quick elimination sequence to resolve parallel questions efficiently.
