(1) skyscrapers were made possible by two innovations in technology: structural steel (steel shaped for use in construction) and the elevator. (2) previously, buildings were supported by their walls. (3) large buildings had to be built with walls of heavy masonry (stonework or brickwork). (4) masonry walls made it difficult to put up structures higher than a hundred feet because the upper walls would weigh too much for the lower stories to bear. (5) steel changed all that completely. (6) the weight of the building could now be borne entirely by a light steel skeleton frame. (7) the outside walls, completely relieved from the duty of supporting weight, were now a mere “skin” and could be made of anything: tiles, metal panels, and glass. (8) and with the elevator, buildings could climb until they scraped the sky.

depends on your school

when i was in high school i took ap biology my senior year and it was the hardest one for me because my teacher finished the material within the first month of school and then went on to doing advanced college level it was horrible. but at a nearby school ap biology was one of the easier aps. also, it depends on what you are interested i like math a lot so ap calculus was easier for me than most but i hate history so ap us government was harder for me than most.

wordsworth tends to see nature as 'out there'; a presence which surrounds humans, and contributes to human life, but is different from humans. if you look at a typical wordsworth poem (there was a boy, ye knew him well ye rocks) - wordsworth talks about nature as something that needs to be learned about and understood, nature is different from us.  

if you look at a byron poem (the isles of greece is a good one) - byron looks at nature mainly for what it already means to man. wordsworth will look at a landscape and see the mountains, trees, valleys, and rivers as almost spiritual presences - wordsworth wants to get to know nature.  

byron will look at the same landscape and he will want to know who lives there, what are the villages? are there any farms or mines, is there some history?  

wordsworth looks at nature for what it is; byron is forever asking what it means.  

wordsworth thinks that humans are part of nature; byron thinks that nature is part of being human
