Problem: With the introduction of the blast furnace to Europe in the Middle Ages, pig iron was able to be produced in much higher volumes than wrought iron. Because pig iron could be melted, people began to develop processes of reducing the carbon in the liquid pig iron to create steel. Puddling was introduced during the 1700s, where molten pig iron was stirred while exposed to the air, to remove the carbon by oxidation. In 1858, Sir Henry Bessemer developed a process of steel-making by blowing hot air through liquid pig iron to reduce the carbon content. The Bessemer process was able to produce the first large scale manufacture of steel. Once the Bessemer process began to gain widespread use, other alloys of steel began to follow. Mangalloy, an alloy of steel and manganese exhibiting extreme hardness and toughness, was one of the first alloy steels, and was created by Robert Hadfield in 1882.
When did puddling start occurring?
The answer is the following: 1700s

Problem: General Bonaparte and his expedition eluded pursuit by the Royal Navy and landed at Alexandria on 1 July. He fought the Battle of Shubra Khit against the Mamluks, Egypt's ruling military caste. This helped the French practice their defensive tactic for the Battle of the Pyramids, fought on 21 July, about 24 km (15 mi) from the pyramids. General Bonaparte's forces of 25,000 roughly equalled those of the Mamluks' Egyptian cavalry. Twenty-nine French and approximately 2,000 Egyptians were killed. The victory boosted the morale of the French army.
What battle did Napoleon fight against the Mamluks?
The answer is the following: the Battle of Shubra Khit

Problem: The foundation has donated billions of dollars to help sufferers of AIDS, tuberculosis and malaria, protecting millions of children from death at the hands of preventable diseases. However, a 2007 investigation by The Los Angeles Times claimed there are three major unintended consequences with the foundation's allocation of aid. First, sub-Saharan Africa already suffered from a shortage of primary doctors before the arrival of the Gates Foundation, but "by pouring most contributions into the fight against such high-profile killers as AIDS, Gates grantees have increased the demand for specially trained, higher-paid clinicians, diverting staff from basic care" in sub-Saharan Africa. This "brain drain" adds to the existing doctor shortage and pulls away additional trained staff from children and those suffering from other common killers. Second, "the focus on a few diseases has shortchanged basic needs such as nutrition and transportation". Third, "Gates-funded vaccination programs have instructed caregivers to ignore even discourage patients from discussing ailments that the vaccinations cannot prevent".
How many children were protected from death
The answer is the following: protecting millions of children from death at the hands of preventable diseases

Problem: Early Asian immigrants experienced prejudice and discrimination in the forms of not having the ability to become naturalized citizens. They also struggled with many of the same school segregation laws that African Americans faced. Particularly, during World War II, Japanese Americans were interned in camps and lost their property, homes, and businesses. Discrimination against Asians began with the Chinese Exclusion Act of 1882 and then continued with the Scott Act of 1888 and the Geary Act of 1892. At the beginning of the 20th century, the United States passed the Immigration Act of 1924 to prevent Asian immigration out of fear that Asians were stealing white jobs and lowering the standard for wages. In addition, whites and non-Asians do not differentiate among the different Asian groups and perpetuate the "model minority" stereotype. According to a 2010 article by Professor Qin Zhang of Fairfield University, Asians are characterized as one dimensional in having great work ethic and valuing education, but lacking in communication skills and personality. A negative outcome of this stereotype is that Asians have been portrayed as having poor leadership and interpersonal skills. This has contributing to the "glass ceiling" phenomenon in which although there are many qualified Asian Americans, they occupy a disproportionately small number of executive positions in businesses. Furthermore, the model minority stereotype has led to resentment of Asian success and several universities and colleges have limited or have been accused of limiting Asian matriculation.
What form of discrimination did early Asian immigrants experience?
The answer is the following:
not having the ability to become naturalized citizens
