I guess you're talking about Animal Farm. Well, the irony is that the animals came together and fought to overthrow the farmers who, they believed, were their greatest enemies, but in fact the greatest enemy of animals was "power." Once the farmers were defeated, the animals achieved their dreamed freedom, until "power" fell on the pigs, they began another kind of exploration and the animals lost their freedom again. That is, as much as there is a fight against an enemy, another will arise, once he has power to concentrate in the hands of a single person, or a single group.
When I talk about this "power", I am referring to being able to be superior and oppressing others, because I think it is more certain, stronger, smarter, etc.
I hope it helps.
The mood of the poem is sad and dark, describing where the bones of someone's father are laying (at the bottom of the ocean.). Alliteration helps convey this mood because the repetition of sounds, especially the 'f' and 's' sounds, make a sound that resembles the rush of waves or the sound you hear if you're underwater.
The first example is in the first line, the 'f' sound is repeated in "Full Fathom Five thy Father lies". Then, for a second example, in lines 4-7, the 's' sound is repeated in "Suffer a Sea-change / Into Something rich and Strange. / Sea-nymphS". Again, those two sounds represent the sound and feeling of being underwater where the body is resting.
I think it's "Pictures display information when written instructions are more complicated". Personally I believe it's just a majorly confusing way of saying: when the written instructions are too complicated they use pictures as well.
