Answer: What were Elizabeth Cady Stanton’s contributions to the women’s suffrage movement? Select three options.

proposed the Declaration of Sentiments

co-founded the National Woman Suffrage Association

lectured in support of suffrage, temperance, and abolition

Explanation:     Major Accomplishments

Elizabeth Cady Stanton was an American social activist, abolitionist, and an important figure in the women's rights movement. She was good friends with Susan B. Anthony, another women's rights activists and together with the help of others arranged the Seneca Falls Convention in Seneca Falls, New York. Her speech, The Declaration of Sentiments, presented at the Seneca Falls Convention in 1848 is often called one of the first steps towards women's rights. Stanton not only addressed voting issues but went beyond that. She talked about divorce, property rights, birth control, employment, custody rights, any many other issues. Stanton was also the 1st president of the National American Woman Suffrage Association (NAWSA). She resigned at the age of 77, and her speech," The Solitude of Self" talked about the issues of women's rights that she had spent her life working on. Elizabeth died in 1902 because of heart failure, and 18 years later in 1820 her goal was reached. The 19th Amendment which granted women the right to vote was passed. She always wanted men and women to be treated the same, and on that day her wish came true. Elizabeth Cady Stanton's legacy was that rights mattered, throughout one's life no matter the size of the issue. She will always be remembered for that.

Elizabeth Cady Stanton was a well-known suffragist in American history, publicly speaking and writing about the inequalities that women faced. Stanton was the first woman to organize the first Woman's Rights Convention, which launched the women's suffrage movement.

Who was Elizabeth Cady Stanton?

Elizabeth Cady Stanton was an American writer and activist who led the women's rights movement in the United States from the mid- to late-nineteenth century. Her demand for women's suffrage sparked debate at the convention, but it quickly became a central tenet of the women's movement.

Stanton contributed significantly to the First Wave of feminism and in particular, the women’s suffrage movement. She also contributed significantly by being the first woman to point out the absence of women’s voting rights by controversially adding the grievance into the Declaration of Sentiments.

Elizabeth Cady Stanton will be remembered as one of the most divisive leaders of the First Wave of feminism and as the founder of the women's suffrage movement.

During the 1850s to 1950s, the primary focus of the public health effort in the united states was to

Answers

Control infectious diseases because in the early 1900s in the United States, many major health threats were infectious diseases associated with poor hygiene and poor sanitation (e.g., typhoid), diseases associated with poor nutrition (e.g., pellagra and goiter), poor maternal and infant health, and diseases or injuries associated with unsafe workplaces or hazardous occupations.

Final answer:

From the 1850s to the 1950s, public health in the U.S. focused on preventing disease through better sanitation, clean water, waste disposal, hygiene education, immunizations, and the introduction of antibiotics. The improvement in public health was part of wider social reforms, including free education and merit-based government employment.

Explanation:

During the period from the 1850s to the 1950s, the primary focus of public health efforts in the United States was the prevention of disease and the promotion of sanitary conditions. Nineteenth-century governments and reformers concentrated on improving sanitation in rapidly industrializing cities to prevent the spread of diseases.

Key public health achievements included the development of systems for providing clean water and the disposal of human waste to help prevent the transmission of diseases. Significant educational campaigns taught the public about the importance of basic hygiene practices such as boiling baby bottles, washing hands, and protecting food from contamination.

In addition to promoting better hygiene practices, scientific advances played a crucial role in increasing life expectancy. Innovations in medicine led to the development of immunizations for diseases like diphtheria, cholera, pertussis, tuberculosis, tetanus, and yellow fever. The discovery of penicillin in 1941 further revolutionized the treatment of infectious diseases, paving the way for other antibiotic drugs which brought many infectious diseases under control.

These efforts were further complemented by social reforms that sought to improve living conditions and public health, such as free education for elementary children and legislation that secured government jobs based on qualifications rather than family background or wealth.

About five thousand years ago, the rains over the Sahara began to decline and grasslands gave way to desert. The population of this region began to migrate east and south. Describe how the landforms and climate of Africa influenced how these people lived as they settled in new areas.


Answers

Over the course of 5000 years, the amount of rain falling over the Sahara drastically decreased. As most of the Sahara is towards the North and mostly inland, it means that less water falls there. The Sahara is huge, covering ~9,000,000 square kilometers. It is called Sahara, because that is translated into desert. The Sahara is mainly stone plateaus, sand seas, and mostly sand dunes. Wind and little rain shapes most of the desert features. Because of this, the area has little suitable places to farm, has little vegetation, and the little vegetation it has consists of shrubs and little grasslands. The place is extremely hot during the days, and has a dramatic contrast during the night. Because of all this, many people that saw that the desert is a harsh area to live in, try to move closer to plains and forests that are still inside Africa. This led to a spread of people from Northern Africa to other parts of the land.
