Read this excerpt from "Mad Cow, Furious Farmer." The disease was first detected in England in 1986, though some scientists think the very first cases started at least ten years before. Cows usually eat only grass and other plants, but farmers had been feeding them a meat and bone mixture that made the cows plumper. But somehow, at least one batch of the mixture had become contaminated with what was then an unknown killer: a prion.

By 1993, British farmers were reporting up to one thousand new cases of BSE a week. Governments all around the world reacted by increasing testing for the disease and not allowing any cows to be eaten if they were at risk of having the disease. As sheep can also get a prion disease called scrapie, they were tested as well. Farmers were angry that they were losing their livestock, and nobody knew how to protect cows and people from the disease.

Consumers were also in a panic when they learned about BSE, and for a very good reason: prions are infectious. If you eat a prion from a "mad cow” or sheep, you are at risk for developing a human version of BSE. The public felt betrayed that their governments had underreacted to the problem or covered it up.

Eventually, in 1997, governments began to ban farmers from feeding their livestock high-risk meat and bone mixtures. With that ban, the epidemic quickly peaked, and by 2010 had largely disappeared. Over the years, half a million cows and two hundred people had been killed by prions.

In the end, the BSE epidemic was a watershed moment, or turning point, in public health. Citizens were enraged at their governments for having kept prions a secret. Governments, who had lost the public trust, struggled to find the best way to communicate health risks without creating unnecessary panic.

How does the author's use of chronology help support the idea that the BSE epidemic was a watershed moment, or turning point, in government use of law to support public health?

The author lays out a timeline to show how scientific discoveries made governments less likely to make laws for public health.
The author makes it clear that prions were always known to be dangerous and that scientists discovered them to be the cause of mad cow disease.
The author discusses how the mad cow disease epidemic ended only about twenty-five years after it first became a problem.
The author shows how frustrated people were that nothing was done about a disease until over ten years after it was discovered.

The answer is: The author shows how frustrated people were that nothing was done about a disease until over ten years after it was discovered.

Explanation:

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.

A.Mad cow disease ended because of government bans on feeding cows certain foods, but people were angry that governments did not act sooner.

Explanation:

The text explains that the disease was identified in 1986.  Seven years later, in 1993, the disease had reached an epidemic level and was causing huge losses to the farmers and panic among the consumers.

In 1997, governments banned some food for the bovines and the epidemic was quickly controlled afterwards.  By 2010, the disease had largely disappeared.

The farmers are angry that the governments didn't help them earlier and the consumers are angry they were put at risk.

Mad cow disease ended because of government bans on feeding cows certain foods, but people were angry that governments did not act sooner.

The excerpt describes why mad cow disease occurred, and how it developed. It began when farmers fed a contaminated mixture of meat and bone to their cows. Although the epidemic ended due to government regulation (which banned those contaminated mixtures), the public was extremely angry at the government. They felt that the government did not act soon enough, and felt betrayed.

The main idea of this excerpt is Mad cow disease ended because of government bans on feeding cows certain foods, but people were angry that governments did not act sooner.  

Explanation:

The disease was first detected in 1986 but it was until 1997 that governments began to ban farmers from feeding their livestock high-risk meat, in the year 2010 the disease had largely disappeared. but a lot of people were killed by it.

Answer:

Step-by-step explanation:

Early photography and Daguerreotype Medium.

Louis Daguerre invented a new process he dubbed a daguerrotype in 1839, which significantly reduced exposure time and created a lasting result, but only produced a single image.

Louis Daguerre called his invention "daguerreotype." His method, which he disclosed to the public late in the summer of 1839, consisted of treating silver-plated copper sheets with iodine to make them sensitive to light, then exposing them in a camera and "developing" the images with warm mercury vapor.

Daguerreotypes became an equalizer among classes. No longer were likenesses only created for the super rich. An average person could walk into a portrait studio, sit for an image, and have the same product as the millionaire down the street. The popularity gave rise to picture factories

Views of modernity and capitalism heavily influenced Daguerre’s discovery because his main goal was to improve and modernize the process previously used to capture images and to upgrade what he saw using camera obscura.

People could start to develop a visual history, not only the rich could afford to have a portrait made, and people could collect images of their friends and family.
