Part 1:

Contaminated water and poor sanitation are linked to transmission of diseases such as cholera, diarrhoea, dysentery, hepatitis A, typhoid, and polio. Absent, inadequate, or inappropriately managed water and sanitation services expose individuals to preventable health risks. This is particularly the case in health care facilities where both patients and staff are placed at additional risk of infection and disease when water, sanitation, and hygiene services are lacking. Globally, 15% of patients develop an infection during a hospital stay, with the proportion much greater in low-income countries.

Inadequate management of urban, industrial, and agricultural wastewater means the drinking-water of hundreds of millions of people is dangerously contaminated or chemically polluted.

Some 829 000 people are estimated to die each year from diarrhoea as a result of unsafe drinking-water, sanitation, and hand hygiene. Yet diarrhoea is largely preventable, and the deaths of 297 000 children aged under 5 years could be avoided each year if these risk factors were addressed. Where water is not readily available, people may decide handwashing is not a priority, thereby adding to the likelihood of diarrhoea and other diseases.

Diarrhoea is the most widely known disease linked to contaminated food and water but there are other hazards. In 2017, over 220 million people required preventative treatment for schistosomiasis – an acute and chronic disease caused by parasitic worms contracted through exposure to infested water.

In many parts of the world, insects that live or breed in water carry and transmit diseases such as dengue fever. Some of these insects, known as vectors, breed in clean, rather than dirty water, and household drinking water containers can serve as breeding grounds. The simple intervention of covering water storage containers can reduce vector breeding and may also reduce faecal contamination of water at the household level.

Part 2:

Although a small minority of people might mention something that happened in therapy, a classroom, or a formal learning experience, the vast majority of cases occurred after recovering from a challenging or even traumatic event—the death of a loved one, a major failure or disappointment, a crisis or catastrophe, a relationship or job ending, a threatening illness, or something similar. We know now from research on this topic that traumatic or difficult events don’t necessarily lead to incapacitating problems but also can spark tremendous growth and learning. In fact, they do so just as often as they may lead to trauma.

Another surprise is that so often change occurs from stories that we read, hear, or see, whether they include family legends, myths, fairy tales, novels, films, television shows, plays, song lyrics, or even blogs such as this. It turns out that because of mirror neurons we can experience vicarious life events as if they really happened to us. As far as your brain is concerned, the people you “meet” in stories really are your friends and loved ones. And the adventures you enjoy through fiction and stories really do teach you important lessons as if you were the one who defeated the zombies, aliens, or serial killer. The strong emotions you feel during a well-told story further cement memories and help you to retrieve information in the future, all without leaving the safety and comfort of a chair.

the correct answer is: reveal gregor as an untidy individual.

in metamorphosis by franz kafka, gregor samsa is the main character, who one day wakes up as a bug, and the attitude he takes upon his transformation forces him to go deeper on his existence and the new features of his body.

in this excerpt the writer mentions a table full of collection textile samples, which gives us a hint about gregor being messy. later on the book we discover how he is a really untidy individual.
