Article: The Niger Delta Nembe Creek Oil field was discovered in 1973 and produces from middle Miocene deltaic sandstone-shale in an anticline structural trap at a depth of 24 km. In June 2013, the company announced a strategic review of its operations in Nigeria, hinting that assets could be divested. While many international oil companies have operated there for decades, by 2014 most were making moves to divest their interests, citing a range of issues including oil theft. In August 2014, Shell Oil Company said it was finalising its interests in four Nigerian oil fields.

Question: What type of geology is the Niger Delta Nembe Creek Oil field?
Ans: middle Miocene deltaic sandstone-shale in an anticline structural trap

Here is a question about this article: Peasant society is much less documented than the nobility. Most of the surviving information available to historians comes from archaeology; few detailed written records documenting peasant life remain from before the 9th century. Most the descriptions of the lower classes come from either law codes or writers from the upper classes. Landholding patterns in the West were not uniform; some areas had greatly fragmented landholding patterns, but in other areas large contiguous blocks of land were the norm. These differences allowed for a wide variety of peasant societies, some dominated by aristocratic landholders and others having a great deal of autonomy. Land settlement also varied greatly. Some peasants lived in large settlements that numbered as many as 700 inhabitants. Others lived in small groups of a few families and still others lived on isolated farms spread over the countryside. There were also areas where the pattern was a mix of two or more of those systems. Unlike in the late Roman period, there was no sharp break between the legal status of the free peasant and the aristocrat, and it was possible for a free peasant's family to rise into the aristocracy over several generations through military service to a powerful lord.
What is the answer to this question: What was a way in which a free peasant might become an aristocrat?
****
So... military service

In 1911 arsphenamine, the first synthetic anti-infective drug, was developed by Paul Ehrlich and chemist Alfred Bertheim of the Institute of Experimental Therapy in Berlin. The drug was given the commercial name Salvarsan. Ehrlich, noting both the general toxicity of arsenic and the selective absorption of certain dyes by bacteria, hypothesized that an arsenic-containing dye with similar selective absorption properties could be used to treat bacterial infections. Arsphenamine was prepared as part of a campaign to synthesize a series of such compounds, and found to exhibit partially selective toxicity. Arsphenamine proved to be the first effective treatment for syphilis, a disease which prior to that time was incurable and led inexorably to severe skin ulceration, neurological damage, and death.[citation needed]
What was the first effective treatment for Syphilis?
****
The answer: Arsphenamine

Problem: Please answer a question about the following article about Light-emitting diode:
A new style of wafers composed of gallium-nitride-on-silicon (GaN-on-Si) is being used to produce white LEDs using 200-mm silicon wafers. This avoids the typical costly sapphire substrate in relatively small 100- or 150-mm wafer sizes. The sapphire apparatus must be coupled with a mirror-like collector to reflect light that would otherwise be wasted. It is predicted that by 2020, 40% of all GaN LEDs will be made with GaN-on-Si. Manufacturing large sapphire material is difficult, while large silicon material is cheaper and more abundant. LED companies shifting from using sapphire to silicon should be a minimal investment.
By using silicon wafers, what is being avoided?
A: costly sapphire substrate

The remaining band members recorded "Independent Women Part I", which appeared on the soundtrack to the 2000 film, Charlie's Angels. It became their best-charting single, topping the U.S. Billboard Hot 100 chart for eleven consecutive weeks. In early 2001, while Destiny's Child was completing their third album, Beyonce landed a major role in the MTV made-for-television film, Carmen: A Hip Hopera, starring alongside American actor Mekhi Phifer. Set in Philadelphia, the film is a modern interpretation of the 19th century opera Carmen by French composer Georges Bizet. When the third album Survivor was released in May 2001, Luckett and Roberson filed a lawsuit claiming that the songs were aimed at them. The album debuted at number one on the U.S. Billboard 200, with first-week sales of 663,000 copies sold. The album spawned other number-one hits, "Bootylicious" and the title track, "Survivor", the latter of which earned the group a Grammy Award for Best R&B Performance by a Duo or Group with Vocals. After releasing their holiday album 8 Days of Christmas in October 2001, the group announced a hiatus to further pursue solo careers.

Their third album, Survivor, sold how many during its first week?
Answer: 663,000 copies

In Southeast Asia, Muslim students have a choice of attending a secular government or an Islamic school. Madaris or Islamic schools are known as Sekolah Agama (Malay: religious school) in Malaysia and Indonesia, (Thai: school of Islam) in Thailand and madaris in the Philippines. In countries where Islam is not the majority or state religion, Islamic schools are found in regions such as southern Thailand (near the Thai-Malaysian border) and the southern Philippines in Mindanao, where a significant Muslim population can be found.
What region of the Philippines has a large Muslim population?
Mindanao
