Thanks. We'll let you know when a new response is added.

Before
we would want to give an answer to this, we would like to know do you have
a business case for asking this question or is it a homework question.

If you have a good business
case for it, please let us know. It is really not right for us to be doing
homework for people. It deprives them of the extra knowledge they get when
doing the research themselves.

    This captcha is basically for security reason. They try to check either the person who sits in front of the computer/ does the transacts are really a human being. This is also a user identification procedure, to determine whether or not the user is human.
