Question Task Patterns

Last week, in response to the news that the ABA approved a proposal that formally removes the requirement that the LSAT be used for admissions purposes we discussed overall structural similarities between GRE and LSAT Reading Comprehension. This week we will compare in more detail similar question tasks on the GRE and the LSAT, specifically on GRE short and medium passage reading comp questions and LSAT Logical Reasoning question tasks. 

While we still strongly advise you to consider the LSAT first for law school admissions, you may find that there is some overlap between preparation you do for the LSAT and the GRE. Equipped with this knowledge, you will be able to make an informed choice between preparing for the LSAT or the GRE, especially if you are considering dual degree, MBA, or other graduate programs.


Overview of Families and Question Types

At PowerScore, we group LSAT Logical Reasoning questions and GRE short form reading comprehension questions into four families based on task and flow of information. 

Four Question Families (2)

Within these categories, LSAT questions can be further divided into thirteen common question tasks. The majority of these questions are drawn from the Prove and Help families.

In contrast, GRE short passage questions are far more limited in scope, drawing primarily from the "Prove" family. On more difficult short passage questions, the GRE introduces concepts derived from the "Help" and "Hurt" families.

In the previous post on LSAT vs GRE Reading Comprehension, we discussed the overall number of questions on each exam that test reading comprehension skills. More narrowly with respect to these questions, we may note that GRE questions that test principles of argumentation will be far less common than they are on the LSAT. Further, these GRE questions are less likely to test sophisticated fallacies or formal logic than are Logical Reasoning questions on the LSAT. 

However, there is one area in which the GRE goes more in depth than does the LSAT in critical thinking: the Argument Task essay, half of the Analytical Writing Measure. In this essay, students must evaluate an argument and write a thorough analysis of its reasoning, including a discussion of its flaws and suggestions for improvement. Nevertheless, the flaws in the stimuli for these Argument essays are usually both numerous and easy to spot with practice. The vast majority of fallacies on the GRE are causal. Hence, you do not need an in-depth knowledge of argumentation to write a compelling Argument essay.


LSAT Question Stems and their GRE Analogs

Let's compare and contrast LSAT Logical Reasoning question stems with their equivalents on the GRE:

Must Be True (Family #1)

  • LSAT
    • "If the above statements are true, which of the following must also be true on the basis of them?"
    • "Based on the information in the passage above, which of the following statements is most strongly supported?"
  • GRE
    • "It can be inferred from the passage that the beneficial nematodes perform which of the following functions? Select all that apply."
    • "The passage suggests which of the following about the effects of cardiovascular exercise?"

Main Point (Family #1)

  • LSAT
    • "Which one of the following best expresses the main conclusion of the argument above?"
    • "Which of the following most accurately expresses the main point of the critic's argument?"
  • GRE
    • "Which of the following best expresses the main point of the passage?"
    • "Which one of the following best expresses the main conclusion of the author's argument?"

Resolve the Paradox (Family #2)

  • LSAT
    • "Which one of the following, if true, would most effectively resolve the apparent paradox above?"
  • GRE
    • "Which of the following would best contribute to an explanation of the difficulty proponents of a more activist judiciary encounter when campaigning for office?"

Strengthen (Family #2)

  • LSAT
    • "Which one of the following, if true, most strengthens the argument?"
    • "Which of the following, if true, would do most to strengthen the reasoning in the statements above?"
  • GRE
    • "Which one of the following, if true, most strengthens the argument?"
    • "Which of the following would be most helpful to bolstering the author's predictions about the future of neuroscience?"

Weaken (Family #3)

  • LSAT
    • "Which one of the following, if true, most seriously weakens the argument?"
    • "Which one of the following, if true, would most serve to undermine the author's conclusion?"
  • GRE
    • "Which one of the following, if true, most undermines the argument?"

Method of Reasoning (Family #1)

  • LSAT
    • "Which one of the following describes the technique of reasoning used above?"
    • "In the argument above, the statement about the effects of caffeine plays which of the following roles?"
  • GRE
    • "In the passage, the two highlighted statements serve which of the following purposes?"
    • "Select the sentence that serves to bolster a claim made in the passage."

There is significant overlap between these tasks on both tests. Notice that on the GRE there is no mention of "above" because all the questions are in a browser frame adjacent to the passage. On a more substantive level, GRE questions tend to feature more concrete language and more direct references to topics within the passages. Further, even though the GRE short passages may only be linked to one question, these passages are on average longer than comparable Logical Reasoning stimuli on the LSAT. In fact, the majority of GRE questions that test principles of argumentation will be drawn from medium-length passages (around 300 words) that are accompanied by two or three questions.

Finally, note that GRE questions sometimes instruct students to highlight a portion of the passage or to select multiple credited answer choices (these are the questions with square boxes instead of ovals for answer choices). 


Preparation is Test-Specific

While a student studying for either the GRE or LSAT may notice similarities in questions on the other test, it remains highly advisable that students consider each of these similar concepts in the context in which they appear on their respective tests. Essentially, a strong foundation in principles of argumentation and critical reasoning skills will serve students well on both tests, but distinctions both in task frequency and question structure mean preparation for one test is not by itself sufficient preparation for the other.

In addition to the differences in nuance between the tests, GRE students must be prepared for the multiple choice-select one-or-more and select-in-passage question types, not to mention the computer-based interface; similarly, LSAT students must prepare for vastly more questions that test logical reasoning and for the more sophisticated concepts tested therein.
