Given the exponential growth of scientific knowledge, medicine is far less (C) vulnerable to unsubstantiated fads than it used to be; its record of folly, however, remains an undeniable embarrassment.

<h3>What is scientific knowledge?</h3>
  • Knowledge can be defined as factual awareness or practical skills, but it can also refer to familiarity with objects or situations.
  • Knowledge of facts, also known as propositional knowledge, is frequently defined as the true belief that differs from opinion or guesswork due to justification.
  • Scientific knowledge is a generalized body of laws and theories developed through the scientific method to explain a phenomenon or behavior of interest.
  • Theories are systematic explanations of the underlying phenomenon or behavior, whereas laws are observed patterns of phenomena or behaviors.

To find the correct option:

  • Option (C) is the correct option because, according to the sentence comparison of medical sciences to scientific knowledge growth, its foolish researches lead to embarrassment.
  • As a result, option (C) is the correct answer.
  • Other options do not correspond to the meaning of the given sentence.

Therefore, given the exponential growth of scientific knowledge, medicine is far less (C) vulnerable to unsubstantiated fads than it used to be; its record of folly, however, remains an undeniable embarrassment.

Hi!
