From an apprentices view, there is nothing on that list that would be hard to identify.
We work with alot of that stuff daily so it is common knowledge.

But, as said before, It would not be wise to think that a "green" apprentice would know what any of that stuff is. If given time anyone can learn those things though.

Just my .02 cents.
