Also, I'd consider the use of an anecdote as a soft persuasive device.
2) Seems like an explanation. The use of language appears relatively neutral with the words "favoured", "arguing" and "said". The wording is as if the author is presenting the argument of another individual, neither supporting nor refuting the argument in question.
3) Seems more like a statement, neither an explanation nor an argument. It sounds somewhat similar to an epigram. The author states that a head is filled with rubbish, but gives no support as to how or even why this is the case. We can only take their word for the fact that it is difficult to force something into another person's head.
