What is an example of an "occasion" statement and what words identify it as such? The question is in reference to a writing rubric.

It is best to start with definitions. An occasion
statement introduces the reason for writing. In other words, an occasion statement can
be any event, idea, or anything else that gives a writer a reason to write. The
statement is usually in the form of a complex sentence and is introduced by one of these
words:

If, After, Since, Before, So that, Whenever, As long
as, In order that, Even though, Although, Unless, While, When, Even, As if, As, Until,
Where, Though, Even if, Because.

Here are some
examples:

If you think that it is fine to talk and chew at
the same time, then consider what happened to these
people. 

Even though wearing a helmet and other protective
equipment seem like a hassle, they are meant to protect you in case of an
accident.

As you can see from these two sentences, they are
setting up an argument, that is, the reason for writing.
