The problem: Answer a question about this article:
Homo sapiens reached the region by around 45,000 years ago, having moved eastwards from the Indian subcontinent. Homo floresiensis also lived in the area up until 12,000 years ago, when they became extinct. Austronesian people, who form the majority of the modern population in Indonesia, Malaysia, Brunei, East Timor, and the Philippines, may have migrated to Southeast Asia from Taiwan. They arrived in Indonesia around 2000 BC,and as they spread through the archipelago, they often settled along coastal areas and confined indigenous peoples such as Negritos of the Philippines or Papuans of New Guinea to inland regions.
Which people became extinct after the Homosapiens arrived?
****
The answer: Homo floresiensis

The problem: Answer a question about this article:
After 1857, the colonial government strengthened and expanded its infrastructure via the court system, legal procedures, and statutes. The Indian Penal Code came into being. In education, Thomas Babington Macaulay had made schooling a priority for the Raj in his famous minute of February 1835 and succeeded in implementing the use of English as the medium of instruction. By 1890 some 60,000 Indians had matriculated. The Indian economy grew at about 1% per year from 1880 to 1920, and the population also grew at 1%. However, from 1910s Indian private industry began to grow significantly. India built a modern railway system in the late 19th century which was the fourth largest in the world. The British Raj invested heavily in infrastructure, including canals and irrigation systems in addition to railways, telegraphy, roads and ports. However, historians have been bitterly divided on issues of economic history, with the Nationalist school arguing that India was poorer at the end of British rule than at the beginning and that impoverishment occurred because of the British.
Who insisted that schooling be a priority in India?
****
The answer: Thomas Babington Macaulay

The problem: Answer a question about this article:
Because sexual orientation is complex and multi-dimensional, some academics and researchers, especially in queer studies, have argued that it is a historical and social construction. In 1976, philosopher and historian Michel Foucault argued in The History of Sexuality that homosexuality as an identity did not exist in the eighteenth century; that people instead spoke of "sodomy," which referred to sexual acts. Sodomy was a crime that was often ignored, but sometimes punished severely (see sodomy law). He wrote, "'Sexuality' is an invention of the modern state, the industrial revolution, and capitalism."
Why do researches in homosexual studies argued that it is a social and historical constuction?
****
The answer: Because sexual orientation is complex and multi-dimensional

The problem: Answer a question about this article:
Because the electron mobility is higher than the hole mobility for all semiconductor materials, a given bipolar npn transistor tends to be swifter than an equivalent pnp transistor. GaAs has the highest electron mobility of the three semiconductors. It is for this reason that GaAs is used in high-frequency applications. A relatively recent FET development, the high-electron-mobility transistor (HEMT), has a heterostructure (junction between different semiconductor materials) of aluminium gallium arsenide (AlGaAs)-gallium arsenide (GaAs) which has twice the electron mobility of a GaAs-metal barrier junction. Because of their high speed and low noise, HEMTs are used in satellite receivers working at frequencies around 12 GHz. HEMTs based on gallium nitride and aluminium gallium nitride (AlGaN/GaN HEMTs) provide a still higher electron mobility and are being developed for various applications.
What is quicker, a bipolar n-p-n transistor or a p-n-p transistor?
****
The answer:
a given bipolar npn transistor
