Yes, the floor, any floor, may be described as 'flooded' if there is a large amount of water on it. In the case of the bathroom, the pipe may be broken or the drainage system may be bad. Either of these situations may lead to flooding of not only the bathroom but also the whole floor of the building.

First, signs often don't follow grammatical rules. Second, you propose a narrow definition of the word flood to prove your point. Using the reasoning that an excess amount of water on the floor is a flood, then the sign is correct and provides the warning needed. The source of the flood is not important, the hazard (flooded floor) is important to the warning.

I like to explain the purpose of citations this way:

1. Citations benefit the reader. When you cite all your sources, you make it possible for your readers to locate the same information and do further research.

2. Citations benefit the original authors. The authors you use or quote in your research deserve recognition for their original work (their intellectual property), so you should give them proper credit through citations and bibliographies.

3. Citations benefit you, the writer, by building your credibility as a researcher. When you cite others' research, you're showing that you're familiar with the relevant scholarship and can therefore be trusted to draw valid conclusions. You increase your authority on that subject and join the "discourse community."

--Maradee Kern, University of Houston-Clear Lake

Citations and bibliographies underscore the amount and quality of research that a writer has done on a topic.

--John Riley, U. of Arkansas

The underlying meaning of using of bibliographies and citations is to give credit to the people of which you got your information from. Even if you put the information in your own words, you still have to cite where you got the information from to give credit to that person. If you don't cite your sources, then you are considered to be plagiarizing the work. The use of bibliographies ties your citations to the original work of which you got your information from. If someone wanted to read further into a particular topic of your work they could get sources from your bibliography to do so. The citations in your paper would give the person an idea of what the sources in your bibliography are about.

"At" refers to the address or location and could include inside the location.

"In" implies inside, only.

"The" is necessary when you refer to a particular object - "the hospital," "the railway station," "the school." If you are using "school" as a generality, the you do not need the article.
