When the alloy cools and solidifies (crystallizes), its mechanical properties will often be quite different from those of its individual constituents. A metal that is normally very soft and malleable, such as aluminium, can be altered by alloying it with another soft metal, like copper. Although both metals are very soft and ductile, the resulting aluminium alloy will be much harder and stronger. Adding a small amount of non-metallic carbon to iron produces an alloy called steel. Due to its very-high strength and toughness (which is much higher than pure iron), and its ability to be greatly altered by heat treatment, steel is one of the most common alloys in modern use. By adding chromium to steel, its resistance to corrosion can be enhanced, creating stainless steel, while adding silicon will alter its electrical characteristics, producing silicon steel.
What is superior to pure iron?
steel

Input: Eritrea
Eritrea is a one-party state in which national legislative elections have been repeatedly postponed. According to Human Rights Watch, the government's human rights record is considered among the worst in the world. Most Western countries have accused the Eritrean authorities of arbitrary arrest and detentions, and of detaining an unknown number of people without charge for their political activism. However, the Eritrean government has continually dismissed the accusations as politically motivated. In June 2015, a 500-page United Nations Human Rights Council report accused Eritrea's government of extrajudicial executions, torture, indefinitely prolonged national service and forced labour, and indicated that sexual harassment, rape and sexual servitude by state officials are also widespread.

According to Human Rights Watch, how do the human rights in Eritrea compare to the rest of the world?
Output: among the worst

Input: Article: By the 2000 census, demographic changes including the end to slavery, immigration from Europe and Asia, assimilation of multiracial persons, and other factors resulted in a population in which 6.2% of the population identified as black, 40% as pardo, and 55% as white. Essentially most of the black population was absorbed into the multi-racial category by intermixing. A 2007 genetic study found that at least 29% of the middle-class, white Brazilian population had some recent (since 1822 and the end of the colonial period) African ancestry.

Now answer this question: How much of the Brazilian population identified as black in 2000?

Output: 6.2%

Article: Regular flights to most villages and towns within the state that are commercially viable are challenging to provide, so they are heavily subsidized by the federal government through the Essential Air Service program. Alaska Airlines is the only major airline offering in-state travel with jet service (sometimes in combination cargo and passenger Boeing 737-400s) from Anchorage and Fairbanks to regional hubs like Bethel, Nome, Kotzebue, Dillingham, Kodiak, and other larger communities as well as to major Southeast and Alaska Peninsula communities.

Question: Which airline offers in-state travel with jet-service?
Ans: Alaska Airlines

Here is a question about this article: The Marshall Islands, officially the Republic of the Marshall Islands (Marshallese: Aolepan Aorokin Majel),[note 1] is an island country located near the equator in the Pacific Ocean, slightly west of the International Date Line. Geographically, the country is part of the larger island group of Micronesia. The country's population of 53,158 people (at the 2011 Census) is spread out over 29 coral atolls, comprising 1,156 individual islands and islets. The islands share maritime boundaries with the Federated States of Micronesia to the west, Wake Island to the north,[note 2] Kiribati to the south-east, and Nauru to the south. About 27,797 of the islanders (at the 2011 Census) live on Majuro, which contains the capital.
What is the answer to this question: Near what major line of latitutde are the Marshall Islands located?
****
So... the equator

Article: Nasser's nationalization of the Suez Canal and his emergence as the political victor from the subsequent Suez Crisis substantially elevated his popularity in Egypt and the Arab world. Calls for pan-Arab unity under his leadership increased, culminating with the formation of the United Arab Republic with Syria (19581961). In 1962, Nasser began a series of major socialist measures and modernization reforms in Egypt. Despite setbacks to his pan-Arabist cause, by 1963 Nasser's supporters gained power in several Arab countries and he became embroiled in the North Yemen Civil War. He began his second presidential term in March 1965 after his political opponents were banned from running. Following Egypt's defeat by Israel in the 1967 Six-Day War, Nasser resigned, but he returned to office after popular demonstrations called for his reinstatement. By 1968, Nasser had appointed himself prime minister, launched the War of Attrition to regain lost territory, began a process of depoliticizing the military, and issued a set of political liberalization reforms. After the conclusion of the 1970 Arab League summit, Nasser suffered a heart attack and died. His funeral in Cairo drew five million mourners and an outpouring of grief across the Arab world.

Question: How many mourners attended Nasser's funeral?
Ans:
five million
