Based upon this very short excerpt, I'd say it develops an atmosphere of chaos.
Answer:
1. Obliterate
2. Old
3. Cleft
4. Decadent
5. Tear
6. Clamorous
Explanation:
1. To annihilate is to destroy something, kill completely. To Annihilate is to get rid of something completely. For example: genocide has the purpose to annihilate (get rid of) human beings who are different, belong to a certain religion or sect. It came from the Late Latin word: "annihilatus" meaning "reduced to nothing", While obliterate means to in Latin to: "struck out", meaning "Trying something with multiple attempt but fail". Anihialate is the action of destroying completely, while obliterate is the action to attempt in annihilation, but, failing multiple times. [Have to try till you get rid of]
2. Antiquity is the past, usually referring before the Middle Ages. While old is something in particular that has aged, has much age.
3. Fissure is an opening on the Earth, it can happen during earthquakes or volcano eruptions. A crack. While cleft is when something is partially divided in two.
4. Dissolution is to have lack of morals referring in a religious manner or society. For example: Having a child before being married is something of great shame in the religious community, in society its normal. Even so, people who are not religious can also have these morals and look bad upon children who are a "bas-ta-rd", a child that was produced out of wed-lock. While decadent is someone who shows a decline in morals, the person is aware of the morals but they themselves "choose" to decline the moral and cultural norms and rules. For example: The U.S prohibits marriage of two or more people. Those who do it disobey the law.
5. Rending is to tear something into two or more pieces. Rending is not done in force, you can tear a piece of paper calmly. To tear is to rip something with force, for example: "He tore with his teeth the flesh upon her skin into two pieces".
6. Tumultuous is to make a loud and confusing noise while clamorous is a racket, its a noise made to be heard or to cause confusion. In Latin it means to "cry out".
Prions are a type of defective proteins, that can cause normal proteins to turn into defective, infectious ones: prion, word that comes from the term "proteinaceous infectious particle"; prions can cause neurodegenerative diseases. Unfortunately, even after scientists identified prions as the causal agents of the "mad cow" disease and others like the "kuru" (discovered in New Guinea, amongst a tribe that practiced cannibalism) and the "scrapie", the authorities tried to hide the epidemic, they took too long to ban the feeding of animals with mixes that included proteins from infected animals, so if authorities had implemented more actions since at least 1993 perhaps the epidemic could have been controlled earlier, instead of almost 25 years after the disease was identified.
In this sense, the author takes us step by step in the process (over time) and illustrates how people got frustrated because of the reaction of the government: nothing was done about the disease until over ten years after its discovery.
I think the answer is OC because in variable line poetry, the intention is to produce this contrast consciously and to produce a rhythm of shorter and longer lines, like the rhythm of shorter and longer sentences.
