Wikipedia:Teahouse host training

What this training is about
Note: This is a draft for discussion, and not a completed page

The Teahouse is a place for new editors to ask any question related to Wikipedia. Editors who answer questions there are referred to as "hosts".

You want to become a host? That is great! There are no formal requirements to start answering questions, so you could start doing that right away.

Unfortunately, practice has shown that new Teahouse hosts often answer questions incorrectly. That is a bad thing.

This page proposes a simple training for new hosts. You will be given questions inspired by or copied from real-case Teahouse questions. You should attempt to answer them in the same manner as you would if you came across those questions for real. Once you have done so, check out the answer page and see how many you have right.

Please keep in mind that
 * 1) The training is entirely optional. You can decide to start answering real questions right away if you feel competent enough.
 * 2) You do not need to submit your answers to Teahouse hosts for judgement. You do not even need to write them out (but make sure to know exactly what you would write before reading the answers page).
 * 3) Even if you answer most or all questions correctly, you might decide that this kind of thing is not for you. That is okay; becoming a host is entirely voluntary, as all of Wikipedia.
 * 4) Even if you answer most or all questions incorrectly, you can still become a host. Read the answers, understand where you went wrong. Ask questions at the Teahouse to clarify if needed. If you are confident you can do well after that, go for it.

The questions
All of the test questions (except the last one) were actually asked at the Teahouse. Try to answer them without looking at answers given by Teahouse hosts or anything the user posted after asking the initial question.

Article rejected although I used almost same wording as another that is accepted
I have written an entry "Elevenish" which was rejected although I used almost the same wording as Matches Fashion as it was deemed by the reviewer as not "neutral". How come the other page is public?
