Hi Mike and welcome to GoY is this a question for an exam or test paper? The reason that I am asking is the answer you will need depends on why you are asking the question.

Yup we can expect a slew of these questions Pamg. Snag is I'm not sure I even understand this question... what does 'important aspects of access' mean? You've obviously got to be able to get to and into a rock garden but (gosh I wish we had emoticons on GoY, I'd be doing to 'duhh' one)

All we can manage is a smile. :0)

Yup
