Default Re: LSAT CR Questions

Some questions for preparation of Law School Admission Test (LSAT) CR or Critical Reasoning/Logical Reasoning section are as follows:

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. After you have chosen the best answer, blacken the corresponding space on your answer sheet.
Question 1
Laird: Pure research provides us with new technologies that contribute to saving lives. Even more worthwhile than this, however, is its role in expanding our knowledge and providing new, unexplored ideas.
Kim: Your priorities are mistaken. Saving lives is what counts most of all. Without pure research, medicine would not be as advanced as it is.
Laird and Kim disagree on whether pure research
derives its significance in part from its providing new technologies
expands the boundaries of our knowledge of medicine
should have the saving of human lives as an important goal
has its most valuable achievements in medical applications
has any value apart from its role in providing new technologies to save lives

Question 2
Executive: We recently ran a set of advertisements in the print version of a travel magazine and on that magazine’s website. We were unable to get any direct information about consumer response to the print ads. However, we found that consumer response to the ads on the website was much more limited than is typical for website ads. We concluded that consumer response to the print ads was probably below par as well.
The executive’s reasoning does which one of the following?
bases a prediction of the intensity of a phenomenon on information about the intensity of that phenomenon’s cause
uses information about the typical frequency of events of a general kind to draw a conclusion about the probability of a particular event of that kind
infers a statistical generalization from claims about a large number of specific instances
uses a case in which direct evidence is available to draw a conclusion about an analogous case in which direct evidence is unavailable
bases a prediction about future events on facts about recent comparable events

Question 3
During the construction of the Quebec Bridge in 1907, the bridge’s designer, Theodore Cooper, received word that the suspended span being built out from the bridge’s cantilever was deflecting downward by a fraction of an inch (2.54 centimeters). Before he could telegraph to freeze the project, the whole cantilever arm broke off and plunged, along with seven dozen workers, into the St. Lawrence River. It was the worst bridge construction disaster in history. As a direct result of the inquiry that followed, the engineering “rules of thumb” by which thousands of bridges had been built around the world went down with the Quebec Bridge. Twentieth-century bridge engineers would thereafter depend on far more rigorous applications of mathematical analysis.
Which one of the following statements can be properly inferred from the passage?
Bridges built before about 1907 were built without thorough mathematical analysis and, therefore, were unsafe for the public to use.
Cooper’s absence from the Quebec Bridge construction site resulted in the breaking off of the cantilever.
Nineteenth-century bridge engineers relied on their rules of thumb because analytical methods were inadequate to solve their design problems.
Only a more rigorous application of mathematical analysis to the design of the Quebec Bridge could have prevented its collapse.
Prior to 1907 the mathematical analysis incorporated in engineering rules of thumb was insufficient to completely assure the safety of bridges under construction.

Question 4
The supernova event of 1987 is interesting in that there is still no evidence of the neutron star that current theory says should have remained after a supernova of that size. This is in spite of the fact that many of the most sensitive instruments ever developed have searched for the tell-tale pulse of radiation that neutron stars emit. Thus, current theory is wrong in claiming that supernovas of a certain size always produce neutron stars.
Which one of the following, if true, most strengthens the argument?
Most supernova remnants that astronomers have detected have a neutron star nearby.
Sensitive astronomical instruments have detected neutron stars much farther away than the location of the 1987 supernova.
The supernova of 1987 was the first that scientists were able to observe in progress.
Several important features of the 1987 supernova are correctly predicted by the current theory.
Some neutron stars are known to have come into existence by a cause other than a supernova explosion.
