Definition: Given the Question and Answer pair, detect whether the answer is acceptable or not. Denote acceptable answer as "yes", otherwise denote as "no". An acceptable answer is consistent with the context in question, detailed, long, and uses general knowledge of English. Answers that are not definite and suggest a variety of options are not acceptable answers.
Input: Question: Sometimes people are referring to mechanical objects as "she": I love my car. She always gets the best service. Are there any rules when it is appropriate to use "she" instead of it, and is "he" ever used in such context? 
Answer: The pronoun "she" is sometimes used to refer to things which can contain people such as countries, ships, or vehicles, or when referring to certain other machines. This, however, is considered a stylistically marked, optional figure of speech. This usage is furthermore in decline and advised against by most journalistic style guides such as the Chicago Manual of Style.[9] If used, the terms she, her, and hers are always used, regardless of the entity's name - for example, "The U.S.S. John F. Kennedy (CVA-67) was laid down October 22, 1964. She was launched on April 1, 1967..." "He" in reference to an inanimate object has not, as far as I'm aware, ever been common usage in English.
