The Correct Answer and Explanation is:
The correct answer is letter.
This question presents an analogy, which requires identifying the relationship between the first pair of words and finding a word that completes the second pair with the same relationship. The analogy is structured as “A is to B as C is to D.”
First, let’s analyze the relationship between “iguana” and “lizard.” An iguana is a specific type, or a particular example, of a lizard. The word “lizard” represents a broader, more general biological classification that includes iguanas, geckos, chameleons, and many other species. Therefore, the relationship is one of a specific example to its general category, or a member to its group.
Now, we must apply this same “specific to general” relationship to the second pair of words: “vowel is to ____.” We need to find a general category to which a vowel belongs. Let’s examine the options provided:
- letter: A vowel (like a, e, i, o, or u) is a specific type of letter. The alphabet is composed of two main categories of letters: vowels and consonants. So, “letter” is the general category that contains vowels. This perfectly mirrors the relationship between “iguana” and “lizard.”
- speech: While vowels are fundamental sounds used in speech, a vowel is not a type of speech. Speech is the complex act of communicating verbally. A vowel is a component or building block of speech, not a category of it. This relationship is one of part to whole, which is different from the specific to general relationship in the first pair.
- language: A vowel is a basic element within a language, but it is not a type of language. English, Spanish, and Mandarin are types of languages. The relationship between “vowel” and “language” is one of a fundamental component to a complex system, which does not match the analogy.
Thus, the most logical and parallel relationship is between “vowel” and “letter.” An iguana is a type of lizard, and a vowel is a type of letter.
