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: Possible Duplicates: Gender neutral pronoun Is it correct to use "their" instead of "his or her"? I am writing software documentation. I have this issue: I am talking about a generic user of the software. Should I say "his preferences", "his/her preferences" or "its preferences"? 
Answer: Do not use the passive voice in documentation addressed to the user. Address all instructions to the person who will follow them. The second person is appropriate, and (as this paragraph demonstrates) does not incur excessive use of the informal "you" if one sticks to the imperative tense. If addressing an administrator who himself has users, refer to the users with male gender as it is the grammatical convention. The problem is easily avoided by referring to them collectively, and using the phrase "the user" often.
