Question 268

Maria: Thomas Edison was one of the most productive inventors of his time, perhaps of all time. His contributions significantly shaped the development of modern lighting and communication systems. Yet he had only a few months of formal schooling. Therefore, you do not need a formal education to make crucial contributions to technological advancement.

Frank: That is definitely not true anymore. Since Edison's day there have been many new developments in technology; to make crucial contributions today you need much more extensive technical knowledge than was needed then.

Frank's reasoning in his response to Maria is most vulnerable to criticism on the grounds that it

Select an option, then click Submit answer.

  • fails to address the possibility that technical knowledge may be acquired without formal education

Question 269

In some countries, there is a free flow of information about infrastructure, agriculture, and industry, whereas in other countries, this information is controlled by a small elite.

  • Economic crises become more frequent as the amount of information available to the population about factors determining its welfare decreases.

  • In nations in which the government controls access to information about infrastructure, agriculture, and industry, economic crises are common.

  • A small elite that controls information about infrastructure, agriculture, and industry is likely to manipulate that information for its own benefit.
