This is a MULTIPLE ANSWER question, which means you are able to select one or more answers as being correct. Note that this does not necessarily mean that there are multiple correct answers. In any case, select all the answers you believe are correct. (NB: There are no part marks awarded for multiple answer questions.)

In your workshop exercises and assignment tasks you have also learned that to successfully solve a problem using a computer language we must express the right semantics, i.e., what we say must make sense. To do so you must understand precisely what each language statement does.

Which of the following claims about a computer language statements semantics is/are correct?

		Given a pattern described by regular expression X, then regular expression X* will match the text sequence 'XXXX' .
		The return statement is used in Python to return a variable to its previous value.
		The Python statement 'new = numbers[3]' puts the value of variable new in position 3 of the sequence.
		In HTML the markup notation text is used to link (also called hyperlink) the bracketed text to another web page.
		The assignment statement apple = melon in Python moves the value of variable melon into variable apple, leaving variable melon equal to null.
