LSAT Logical Reasoning Sample Questions

Directions: The questions in this section are based on the reasoning contained in brief statements or passages. For some questions, more than one of the choices could conceivably answer the question. However, you are to choose the best answer; that is, the response that most accurately and completely answers the question. You should not make assumptions that are by commonsense standards implausible, superfluous, or incompatible with the passage.

1. When teaching art students about the use of color, teachers should use colored paper rather than paint in their demonstrations. Colored paper is preferable because it readily permits a repeated use of exactly the same color in different compositions, which allows for a precise comparison of that color’s impact in varying contexts. With paint, however, it is difficult to mix exactly the same color twice, and the varying textures of the applied paint can interfere with the pure effect of the color itself.

Which one of the following is an assumption required by the argument?

A. Two pieces of paper of exactly the same color will have the same effect in a given context, even if they are of different textures.

B. A slight difference in the color of two pieces of paper is more difficult to notice than a similar difference in the color of two samples of paint.

C. Changing light conditions have less of an effect on the apparent color of a piece of paper than on the apparent color of a sample of paint.

D. Observing the impacts of colors across varying contexts helps students to learn about the use of color.

E. It is important that art students understand how the effects of using colored paper in various compositions differ from those of using paint in those compositions.

2. Copyright was originally the grant of a temporary government-supported monopoly on copying a work. Its sole purpose was to encourage the circulation of ideas by giving authors the opportunity to derive a reasonable financial reward from their works.

The conclusion of the argument is most strongly supported if which one of the following completes the passage?

A. publication of copyrighted works is not the only way to circulate ideas

3. Union member: Some members of our labor union are calling for an immediate strike. But a strike would cut into our strike fund and would in addition lead to a steep fine, causing us to suffer a major financial loss. Therefore, we must not strike now.

The union member’s argument is most vulnerable to criticism on the grounds that it

A. fails to consider that a strike might cause the union to suffer a financial loss even if no fine were imposed

B. fails to define adequately what constitutes a major financial loss

C. fails to consider that the benefits to be gained from a strike might outweigh the costs

D. takes for granted that the most important factor in the labor union’s bargaining position is the union’s financial strength

E. fails to establish that there will be a better opportunity to strike at a later time

4. In trying to reduce the amount of fat in their diet, on average people have decreased their consumption of red meat by one-half in the last two decades. However, on average those who have reduced their consumption of red meat actually consume substantially more fat than those who have not.

Which one of the following, if true, most helps to resolve the apparent discrepancy described above?

A. Many more people have reduced their consumption of red meat over the last two decades than have not.

B. Higher prices over the last two decades have done as much to decrease the consumption of red meat as health concerns have.

C. People who reduce their consumption of red meat tend to consume as much of other foods that are high in fat as do those who have not reduced their consumption of red meat.

D. People who reduce their consumption of red meat tend to replace it with cheese and baked goods, which are richer in fat than red meat.

E. Studies have shown that red meat contains slightly less fat than previously thought.

5. Watching music videos from the 1970s would give the viewer the impression that the music of the time was dominated by synthesizer pop and punk rock. But this would be a misleading impression. Because music videos were a new art form at the time, they attracted primarily cutting-edge musicians.

Which one of the following arguments is most similar in its reasoning to that of the argument above?

A. Our view of pre-printing-press literature can never be accurate, because the surviving works of ancient authors are those that were deemed by copyists most likely to be of interest to future readers.

B. Our memory of 1960s TV shows could hardly be improved, because so many of the television programs of the era are still rerun today.

C. Future generations’ understanding of today’s publishing trends will be distorted if they judge by works published in CD-ROM format, since it is primarily publishers interested in computer games that are using CD-ROM.

D. Our understanding of silent films is incomplete, because few filmmakers of the time realized that the film stock they were using would disintegrate over time.

E. Our notion of fashion trends will probably be accurate if we rely on TV fashion programs, despite the fact that these programs deliberately select the most outrageous outfits in order to get the viewers’ attention.
