Article: The first institute of madrasa education was at the estate of Hazrat Zaid bin Arkam near a hill called Safa, where Hazrat Muhammad was the teacher and the students were some of his followers.[citation needed] After Hijrah (migration) the madrasa of "Suffa" was established in Madina on the east side of the Al-Masjid an-Nabawi mosque. Hazrat 'Ubada bin Samit was appointed there by Hazrat Muhammad as teacher and among the students.[citation needed] In the curriculum of the madrasa, there were teachings of The Qur'an,The Hadith, fara'iz, tajweed, genealogy, treatises of first aid, etc. There were also trainings of horse-riding, art of war, handwriting and calligraphy, athletics and martial arts. The first part of madrasa based education is estimated from the first day of "nabuwwat" to the first portion of the "Umaiya" caliphate.[citation needed]

Question: Who was named as a teacher at the second madrasa, housed in a mosque?
Ans: Hazrat 'Ubada bin Samit

Article: One of the ways to prevent or slow down the transmission of infectious diseases is to recognize the different characteristics of various diseases. Some critical disease characteristics that should be evaluated include virulence, distance traveled by victims, and level of contagiousness. The human strains of Ebola virus, for example, incapacitate their victims extremely quickly and kill them soon after. As a result, the victims of this disease do not have the opportunity to travel very far from the initial infection zone. Also, this virus must spread through skin lesions or permeable membranes such as the eye. Thus, the initial stage of Ebola is not very contagious since its victims experience only internal hemorrhaging. As a result of the above features, the spread of Ebola is very rapid and usually stays within a relatively confined geographical area. In contrast, the Human Immunodeficiency Virus (HIV) kills its victims very slowly by attacking their immune system. As a result, many of its victims transmit the virus to other individuals before even realizing that they are carrying the disease. Also, the relatively low virulence allows its victims to travel long distances, increasing the likelihood of an epidemic.

Question: Why is the initial stage of Ebola not very contagious?
Ans: victims experience only internal hemorrhaging

Article: His next relationship was with Herta Haas, whom he married in 1940. Broz left for Belgrade after the April War, leaving Haas pregnant. In May 1941, she gave birth to their son, Aleksandar "Miso" Broz. All throughout his relationship with Haas, Tito had maintained a promiscuous life and had a parallel relationship with Davorjanka Paunovic, who, under the codename "Zdenka", served as a courier in the resistance and subsequently became his personal secretary. Haas and Tito suddenly parted company in 1943 in Jajce during the second meeting of AVNOJ after she reportedly walked in on him and Davorjanka. The last time Haas saw Broz was in 1946. Davorjanka died of tuberculosis in 1946 and Tito insisted that she be buried in the backyard of the Beli Dvor, his Belgrade residence.

Question: Who did Tito marry in 1940?
Ans: Herta Haas

Article: Canadian bitumen does not differ substantially from oils such as Venezuelan extra-heavy and Mexican heavy oil in chemical composition, and the real difficulty is moving the extremely viscous bitumen through oil pipelines to the refinery. Many modern oil refineries are extremely sophisticated and can process non-upgraded bitumen directly into products such as gasoline, diesel fuel, and refined asphalt without any preprocessing. This is particularly common in areas such as the US Gulf coast, where refineries were designed to process Venezuelan and Mexican oil, and in areas such as the US Midwest where refineries were rebuilt to process heavy oil as domestic light oil production declined. Given the choice, such heavy oil refineries usually prefer to buy bitumen rather than synthetic oil because the cost is lower, and in some cases because they prefer to produce more diesel fuel and less gasoline. By 2015 Canadian production and exports of non-upgraded bitumen exceeded that of synthetic crude oil at over 1.3 million barrels (21010^3 m3) per day, of which about 65% was exported to the United States.

Question: What industry is capable of refining bitumen directly into gasoline without preprocessing?
Ans:
modern oil refineries
