One of the pieces of music you studied was requiem in d minor, k. 626, written by wolfgang amadeus mozart. it is considered an intense piece of music because: a) it is very long and very loud
b) it has complex rhythms
c) it has complex melodies
d) all of the above

it is D. all of the above.  if you listen to the song it is verry loud after a few second, the song is about 40 mins or so, if you look at the sheet music it is very complex.

"the idea of humanism is mostly adeptly reflected in renaissance art by a focus on the body itself, especially with sculpture, where many detailed portraits of the human body (such as the david) were created."

i'm not too sure - if you could attach the picture
