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.

The correct answers are 1, 3 and 4. Charles Darwin's work introduced a new focus on Realism, inspired Naturalism in art and ushered in Impressionism. Naturalistic writers and artists were inspired by the evolution theory of Charles Darwin. Naturalism was developed as a new branch of Realism. Its basic theory is that one's heredity and social environment determine one's character and influence the action of its subjects. Naturalism was a novel and stricter realism. Degas, Monet and Cezanne, three of the most important impressionist artists, were deeply influenced by the Darwinian theories.
