Problem: Geography of the United States:

These areas contain some spectacular scenery as well, as evidenced by such national parks as Yosemite and Mount Rainier. West of the Cascades and Sierra Nevada is a series of valleys, such as the Central Valley in California and the Willamette Valley in Oregon. Along the coast is a series of low mountain ranges known as the Pacific Coast Ranges. Much of the Pacific Northwest coast is inhabited by some of the densest vegetation outside of the Tropics, and also the tallest trees in the world (the Redwoods).

What are the low mountain ranges that are located along the pacific coast called?

A: Pacific Coast Ranges

Problem: By the 1890s the profound effect of adrenal extracts on many different tissue types had been discovered, setting off a search both for the mechanism of chemical signalling and efforts to exploit these observations for the development of new drugs. The blood pressure raising and vasoconstrictive effects of adrenal extracts were of particular interest to surgeons as hemostatic agents and as treatment for shock, and a number of companies developed products based on adrenal extracts containing varying purities of the active substance. In 1897 John Abel of Johns Hopkins University identified the active principle as epinephrine, which he isolated in an impure state as the sulfate salt. Industrial chemist Jokichi Takamine later developed a method for obtaining epinephrine in a pure state, and licensed the technology to Parke Davis. Parke Davis marketed epinephrine under the trade name Adrenalin. Injected epinephrine proved to be especially efficacious for the acute treatment of asthma attacks, and an inhaled version was sold in the United States until 2011 (Primatene Mist). By 1929 epinephrine had been formulated into an inhaler for use in the treatment of nasal congestion.
Who identified the active substance?

Answer: John Abel

Although the number of base-pairs of DNA in the human genome has been known since the 1960s, the estimated number of genes has changed over time as definitions of genes, and methods of detecting them have been refined. Initial theoretical predictions of the number of human genes were as high as 2,000,000. Early experimental measures indicated there to be 50,000100,000 transcribed genes (expressed sequence tags). Subsequently, the sequencing in the Human Genome Project indicated that many of these transcripts were alternative variants of the same genes, and the total number of protein-coding genes was revised down to ~20,000 with 13 genes encoded on the mitochondrial genome. Of the human genome, only 12% consists of protein-coding genes, with the remainder being 'noncoding' DNA such as introns, retrotransposons, and noncoding RNAs.
What percentage of the human genome consists of protein coding genes?
A: 12%

Context and question: Referred to as "Hyderabadi", the residents of Hyderabad are predominantly Telugu and Urdu speaking people, with minority Bengali, Gujarati (including Memon), Kannada (including Nawayathi), Malayalam, Marathi, Marwari, Odia, Punjabi, Tamil and Uttar Pradeshi communities. Hyderabad is home to a unique dialect of Urdu called Hyderabadi Urdu, which is a type of Dakhini, and is the mother tongue of most Hyderabadi Muslims, a unique community who owe much of their history, language, cuisine, and culture to Hyderabad, and the various dynasties who previously ruled. Hadhrami Arabs, African Arabs, Armenians, Abyssinians, Iranians, Pathans and Turkish people are also present; these communities, of which the Hadhrami are the largest, declined after Hyderabad State became part of the Indian Union, as they lost the patronage of the Nizams.
What is the main language of most Muslims from Hyderabad?
Answer: Hyderabadi Urdu

Question: Seminole Indians based in East Florida began raiding Georgia settlements, and offering havens for runaway slaves. The United States Army led increasingly frequent incursions into Spanish territory, including the 18171818 campaign against the Seminole Indians by Andrew Jackson that became known as the First Seminole War. The United States now effectively controlled East Florida. Control was necessary according to Secretary of State John Quincy Adams because Florida had become "a derelict open to the occupancy of every enemy, civilized or savage, of the United States, and serving no other earthly purpose than as a post of annoyance to them.".
Is there an answer to this question: Where did Seminole Indians not raid?

Answer: unanswerable

In New York City in 1846, Alexander Turney Stewart established the "Marble Palace" on Broadway, between Chambers and Reade streets. He offered European retail merchandise at fixed prices on a variety of dry goods, and advertised a policy of providing "free entrance" to all potential customers. Though it was clad in white marble to look like a Renaissance palazzo, the building's cast iron construction permitted large plate glass windows that permitted major seasonal displays, especially in the Christmas shopping season. In 1862, Stewart built a new store on a full city block with eight floors and nineteen departments of dress goods and furnishing materials, carpets, glass and china, toys and sports equipment, ranged around a central glass-covered court. His innovations included buying from manufacturers for cash and in large quantities, keeping his markup small and prices low, truthful presentation of merchandise, the one-price policy (so there was no haggling), simple merchandise returns and cash refund policy, selling for cash and not credit, buyers who searched worldwide for quality merchandise, departmentalization, vertical and horizontal integration, volume sales, and free services for customers such as waiting rooms and free delivery of purchases. His innovations were quickly copied by other department stores.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Where was the "Marble Palace" built in 1864?
Ah, so..
