Arrange the following in order of increasing connotation:
A. Domestic Animal
B. Animal
C. Horse
D. Beast of burden
Choose the correct answer from the options given below:

The correct answer is B, A, C, D.

To understand why this is the correct order, we must understand the relationship between connotation (intension) and denotation (extension) of terms:
1. Connotation refers to the set of attributes, qualities, or characteristics that define a term.
2. Denotation refers to the actual class of objects or members that the term applies to.
3. There is an inverse relationship between the two. As a term becomes more specific, its denotation (the number of objects it applies to) decreases, while its connotation (the number of defining attributes) increases.

Let's analyze the connotation of each term from the least specific (fewest attributes) to the most specific (most attributes):

1. B. Animal:
This is the most general term in the list. It applies to all living organisms in the kingdom Animalia. Because it is extremely broad, it has the widest denotation but the lowest connotation (fewest defining attributes).

2. A. Domestic Animal:
This term adds a specific attribute to "Animal"—namely, being tamed or kept by humans. Since it requires this additional characteristic, its connotation is greater than that of "Animal", while its denotation is smaller (excluding wild animals).

3. C. Horse:
This refers to a specific species. A horse has all the attributes of an animal, plus numerous specific biological characteristics (such as hooves, a mane, and a specific skeletal structure). This increases the connotation further.

4. D. Beast of burden:
This term adds the highly specific functional attribute of being used by humans for carrying heavy loads or performing manual labor. In this sequence, it represents the most specialized classification with the narrowest class of applicable animals, thus having the highest connotation.

Therefore, arranging the terms in order of increasing connotation (from the most general to the most specific) gives us: B, A, C, D.
