Question 22

Comprehension
JAMB 2002 Passage IV: Defining words
If our thought is to be clear and we are to succeed in communicating it to other people, we must have some method of fixing the meaning of the words we use. When we use a word whose meaning is not certain, we may well be asked to define it. There is a useful traditional device for doing this by indicating the class to which whatever is indicated by the term belongs, and also other particular property which distinguishes it from all other members of the same class. Thus we may define a whale as a 'marine animal that spouts.' 'Marine animal' in this definition indicates the general class to which the whale belongs, and 'spouts' indicates the particular property that distinguishes whales from other such marine animals as fishes, seals, jellyfish and lobsters. In the same way, we can define an even number as a finite integer divisible by two, or a democracy as a system [about two lines unreadable in the book] … find it hard to make a suitable definition of the word 'animal', so we say that an animal is such a thing as a rabbit, dog, fish or goat. Similarly we may say that religion is such a system as Christianity, Islam, Judaism and Buddhism. This way of indicating the meaning of a term by enumerating examples of what it includes is obviously of limited usefulness. If we indicated our use of the word 'animal' as above, our hearers might, for example, be doubtful whether a sea-anemone or a slug was to be included in the class of animals. It is, however, a useful way of supplementing a definition if the definition itself is definite without being easily understandable. Failure of an attempt at definition to serve its purpose may result from giving as distinguishing mark one which either does not belong to all the things the definition is intended to include, or does belong to some members of the same general class which the definition is intended to exclude.

Adapted from Straight and Crooked Thinking, by R. H. Thouless

One of these summarizes the approaches to definition discussed in the passage

  1. A.Mentioning the class of a word or object with its specific property
  2. B.Indicating the class of a word and mentioning its general property with examples
  3. C.Specifying clearly what distinguishes a particular word or object from its traditional groups
  4. D.Giving general and specific features followed by examples of what the object or word includes
Show the answer and explanation

Answer: D (Giving general and specific features followed by examples of what the object or word includes)

Explanation

The passage describes defining by general class plus a distinguishing property, and then defining by listing examples, which D combines.
