The question involves finding the correct analogy. We are given "spoke : ............ :: word : sentence". To solve this analogy, we need to identify the relationship between a "spoke" and the missing word, similar to how a "word" relates to a "sentence".
A "word" is a part of a "sentence". Similarly, we need to find what a "spoke" is a part of.
Let's analyze the options:
- Speaker: A "speaker" is not a part of a "spoke".
- Paragraph: A "paragraph" is not related to a "spoke" in the way a "word" is to a "sentence".
- Wheel: A "spoke" is a part of a "wheel", much like how a "word" is a part of a "sentence".
- Comma: A "comma" is a punctuation mark, not related to "spoke".
From the analysis, the correct analogy is:
spoke : wheel :: word : sentence
Therefore, the correct answer is:
wheel
