I. Parallelism


Parallel questions involve finding the answer choice that mostly resembles the idea or principle behind the question. You can spot parallel questions by looking at language cues that tell you to compare reasoning structures such as:

  • Most similar
  • Most closely resemble
  • Most parallels

Solving parallel questions

  1. Find the conclusion of the argument.
  2. Find pieces of evidence that are used to support the conclusion.
  3. Find the relation between the conclusion and the evidence and evaluate the reasoning behind them.

Anticipate what the correct answer would look like, and avoid falling into answer choice traps.

II. Principle Questions

Principle Questions

Principle questions ask you to identify the principles behind arguments and choose which of the answer choices similarly conforms to those principles. A principle is a general rule that can be applied to many instances including the case presented in the passage. Some language cues that can help you identify principle questions are ‘principle,’ ‘proposition,’ and ‘generalization.’

III. Parallel Flaw

Parallel Flaw

Parallel flaw questions are similar to principle questions but instead of identifying similar principles, you will identify similar flaws between the question and one of the answer choices. This type of question is easier to spot because it will explicitly ask you to identify which of the choices most closely resembles the flawed pattern of reasoning in the question.

IV. Agree/Disagree


This type of question involves two arguments from two different characters. Your task is to identify what the point of  issue is or what the characters in the passage are agreeing or disagreeing about. The key to answering agree/disagree questions is to find overlapping statements and anticipate the correct answer from there. Also, beware of answer choices that may seem tempting but are not actually relevant to the dispute.

The correct answers to most LSAT questions will have a middle focus. Don’t choose overly broad answers that the passage can’t support, and don’t choose overly narrow choices because passages usually aren’t that focused. Take a look at this example.

The author is primarily concerned with:

A. Penguin mating patterns
B. Antarctic Penguins
Birds of the world
D. Penguin behavior and life cycle
E. Animals of the Southern Hemisphere

B is likely to be correct as it is closest to the middle scope. It deals with an animal and its habitat. It is not too narrow, but it’s also not too broad. It fits nicely in between:

Animals of the Southern Hemisphere
Birds of the world
Penguin behavior and life cycle
Penguin mating patterns

Watch out for words like all, never, always, and only. These qualifiers are strong and are usually outside a passage’s scope. Just think how hard it would be to write a short passage that argued:

  • Every new medical treatment improves the quality of medical care. (No failures at all?)
  • Only the federal government can improve public school education. (What about states? Individuals?)

Look for answers that use some, most, or many. These qualifiers indicate a limited scope.

Does every reading comprehension question have one correct answer and four incorrect answers?

Yes, you say? Well . . . not exactly. Rather, there is one best answer and four not-so-good answers.

For example, Main Idea questions generally have one or two answers that are partly correct but flawed in some way. A wrong answer to the question “What is the main idea?” might summarize the main idea of only part of the passage.

Your goal is to pick the best answer to the question, not hunt for the One True Answer.

Unless you are highly pressed for time, always read all answer choices before making a decision. An answer that seems basically right could be rendered incomplete by a better choice. Do not ask yourself if an answer is correct. Ask yourself if it is better than the other choices.

Which of the following assertions in the passage is supported by an example?

Now, turn it on its head:

Which of the following assertions in the passage is NOT supported by an example?

What can you do? Practice! You have to learn to reverse your thinking. Practice assists in acquiring that skill. One pitfall is to overlook the critical reversal word and then wonder why all the choices seem correct. NOT, LEAST, and EXCEPT will be used in caps to indicate you’re looking for the reverse answer. Rephrasing the question before you answer is helpful.
