Final answer:
The statement "Your body is an engine and water is its oil" is an example of a simile, using a comparison to describe the role of water in the human body in comparison to oil in an engine, which makes the correct option a) True.
Step-by-step explanation:
The statement "Your body is an engine and water is its oil" is indeed an example of a simile. In English, a simile is a figure of speech that compares two different things using the word 'like' or 'as'. This comparison helps emphasize certain qualities of the things being compared by highlighting their similarities. In the case of the human body, the comparison to a well-tuned machine emphasizes the importance of water for our bodily functions, comparable to how oil is essential for an engine's operation.
Similar to machines, which have many interacting parts that work together to perform a function, the human body has various organs and systems that collaborate to sustain life. The idea of the body as a machine is often used to conceptualize how complex and efficient it is. For example, the circulatory system can be likened to a distribution network, and the brain could be compared to a computer's processor. Therefore, the correct option for whether this statement is an example of a simile is: True.
