<p>ya i got like 4 wrong already cause of such silly mistakes.. that was an easy sencom right?;</p>
<p>I do not think there was such an option as "common practices" for that question. There was "established practices" or something of that sort; that is what I selected.</p>
<p>Ah yes I remember now, "established practices" was the answer. It was neither "common practices" nor "established rules" but a combination of the two. Interesting how that worked out.</p>
