Which place would be the best example of a Gothic setting? A. A meadow filled with flowers B. A beautiful enchanted forest C. A
marin [14]
When I think of Gothic, I don't think of anything positive, so A would definitely not be it. The same thing with B. Anything with beautiful, sparkling, bright and colourful things just doesn't scream goth.

For C, I could see where it would be going with using a jail yard as a setting, but since the answer specifically says on a sunny afternoon, then I don't think that would be correct either. When people think sunny, they usually think happy.

I think D would be most accurate. It doesn't seem like it would have any positive attributes, and it would probably even make some people uneasy.

So yeah, I'm not 100% sure, but this is the best I can do to figure it out. I think D would be the best choice! :)

In at least 150 words, discuss the significance iron plays in Jack Agueros’s story “'Agua Viva,' A Sculpture by Alfred Gonzalez.
mart [117]

Jacks Agueros's “'Agua Viva,' A Sculpture by Alfred Gonzalez" tells the story of Filthy Fredo, a hermit that collects scrap iron to build creations in his workshop. Filthy Fredo, is mentally unstable, hasn't shave or take a bath in five years, and the only human interaction that he had during the story is with some neighborhood boys which resulted to be violent at first glance. The author uses iron as a metaphor to Fredo's obsessive world, which is impenetrable as the iron creations that he builds for defense against the real world. One excerpt of the story that implies this conclusion is "His house had become the lair of the iron woodchuck, the hive of the iron bee, the storeroom of the iron squirrel, the complex of chambers of the iron ant". The iron served as the metaphoric armor of Fredo, and the only thing he enjoyed to do as a hermit. However, he eventually had to deal with the consequences of the life he decided to live and his inevitable return to society.
