The correct answer is B.
When producers develop an absolute advantage, they are able to manufacture products or services more efficiently that the competitors. This means they are able to produce a larger quantity of output with the same amount of inputs than the competitors, or the same level of output with fewer inputs.
When a production process becomes more efficient, there is a <u>cost reduction and manufacturers are able to decrease the market prices of the products </u>and, in consequence, to increase their sales and profits. <u>Hence. due to the price reduction, competitiveness constitutes a benefit for consumers too, as they can purchase the same products at a cheaper price. </u>
The correct answer is C. Sending Polish Jews to a concentration map
Explanation:
During the Second World War from 1939 to 1945, the German forces led by Adolf Hitler and the Nazi Party invaded and controlled other countries of Europe including Poland. Considering the Nazis do only aimed at attacking the opposing military forces or the allies, but were guided by the idea of considering certain persons in the society had undesirable racial features and should be exterminated, this included Jews, Gypsies, Poles, and disabled people. Because of this, when the German forces invaded Poland most of the Polish people, especially Jews were forced to leave their houses and were taken to concentration camps where most of them died.
Bearing in mind the photo was taken in 1943 when all the situation described before was taking place then and that the people in the picture are not returning home but going out of them with German soldiers supervising all the process and that the body language of people suggest they are surrendering and feel scared it can be concluded the photograph shows how the German forces were sending Polish Jews to a concentration map; as during this historical period the German forces aimed at extermining Jews but never protecting, liberating or accompanying them.
Malaria
Dr. John Gorrie practiced medicine in Florida. He experimented with ways to prevent the spread of malaria. The summer of 1841 was a particularly bad summer for malaria infection. People had not yet realized that malaria was spread by mosquitoes. (That discovery didn't occur till the 1890s.) Dr. Gorrie, noting that malaria was unlikely to occur in colder climates, thought that perhaps cooling the air in the sick rooms of his patients could help them. He started with the idea of using a fan to blow air across a bucket of ice. A rudimentary beginning to air cooling and refrigeration ... but as they say, the rest is history!
