Under what circumstances do the following two methods of binding a click event to a paragraph not behave the same:

$("p").live("click", function() { alert("p clicked") })

$("p").click(function(){ alert("p clicked") });

How would you write a selector that selects the following

1. All the elements on a page
2. All the paragraphs with class "big"
3. The first paragraph with the div with id "main"
4. The odd rows of a table
5. The input elements of type "textarea"
