Question 166

People ought to take into account a discipline's blemished origins when assessing the scientific value of that discipline. Take, for example, chemistry. It must be considered that many of its landmark results were obtained by alchemists – a group whose superstitions and appeals to magic dominated the early development of chemical theory. The reasoning above is most susceptible to criticism because the author

  • fails to establish that disciplines with unblemished origins are scientifically valuable

  • fails to consider how chemistry's current theories and practices differ from those of the alchemists mentioned

  • uses an example to contradict the principle under consideration

  • does not prove that most disciplines that are not scientifically valuable have origins that are in some way suspect

  • uses the word "discipline" in two different senses

Question 167

Question 168

The current theory about earthquakes holds that they are caused by adjoining plates of rock sliding past each other; the plates are pressed together until powerful forces overcome the resistance. As plausible as this may sound, at least one thing remains mysterious on this theory. The overcoming of such resistance should create enormous amounts of heat. But so far no increases in temperature unrelated to weather have been detected following earthquakes.

Which one of the following most accurately expresses the main point of the argument?

Select an option, then click Submit answer.

  • No increases in temperature have been detected following earthquakes.

  • The current theory does not fully explain earthquake data.

  • No one will ever be sure what the true cause of earthquakes is.

  • Earthquakes produce enormous amounts of heat that have so far gone undetected.

  • Contrary to the current theory, earthquakes are not caused by adjoining plates of rock sliding past one another.
