Prior to the 20th century drugs were generally produced by small scale manufacturers with little regulatory control over manufacturing or claims of safety and efficacy. To the extent that such laws did exist, enforcement was lax. In the United States, increased regulation of vaccines and other biological drugs was spurred by tetanus outbreaks and deaths caused by the distribution of contaminated smallpox vaccine and diphtheria antitoxin. The Biologics Control Act of 1902 required that federal government grant premarket approval for every biological drug and for the process and facility producing such drugs. This was followed in 1906 by the Pure Food and Drugs Act, which forbade the interstate distribution of adulterated or misbranded foods and drugs. A drug was considered misbranded if it contained alcohol, morphine, opium, cocaine, or any of several other potentially dangerous or addictive drugs, and if its label failed to indicate the quantity or proportion of such drugs. The government's attempts to use the law to prosecute manufacturers for making unsupported claims of efficacy were undercut by a Supreme Court ruling restricting the federal government's enforcement powers to cases of incorrect specification of the drug's ingredients.
What law banned the interstate distribution of mislabeled food and drugs? 
Pure Food and Drugs Act


Input: Sichuan
Mianyang Hi-Tech Industrial Development Zone was established in 1992, with a planned area of 43 km2 (17 sq mi). The zone is situated 96 kilometers away from Chengdu, and is 8 km (5.0 mi) away from Mianyang Airport. Since its establishment, the zone accumulated 177.4 billion yuan of industrial output, 46.2 billion yuan of gross domestic product, fiscal revenue 6.768 billion yuan. There are more than 136 high-tech enterprises in the zone and they accounted for more than 90% of the total industrial output.

What is the distance between the Mianyang Hi-Tech Industrial Development Zone and Mianyang Airport?
Output: 8 km


Input: Article: Bacterial growth follows four phases. When a population of bacteria first enter a high-nutrient environment that allows growth, the cells need to adapt to their new environment. The first phase of growth is the lag phase, a period of slow growth when the cells are adapting to the high-nutrient environment and preparing for fast growth. The lag phase has high biosynthesis rates, as proteins necessary for rapid growth are produced. The second phase of growth is the log phase, also known as the logarithmic or exponential phase. The log phase is marked by rapid exponential growth. The rate at which cells grow during this phase is known as the growth rate (k), and the time it takes the cells to double is known as the generation time (g). During log phase, nutrients are metabolised at maximum speed until one of the nutrients is depleted and starts limiting growth. The third phase of growth is the stationary phase and is caused by depleted nutrients. The cells reduce their metabolic activity and consume non-essential cellular proteins. The stationary phase is a transition from rapid growth to a stress response state and there is increased expression of genes involved in DNA repair, antioxidant metabolism and nutrient transport. The final phase is the death phase where the bacteria run out of nutrients and die.

Now answer this question: How many phase are in the growth of bacteria?

Output: four phases


Article: In London Chopin took lodgings at Dover Street, where the firm of Broadwood provided him with a grand piano. At his first engagement, on 15 May at Stafford House, the audience included Queen Victoria and Prince Albert. The Prince, who was himself a talented musician, moved close to the keyboard to view Chopin's technique. Broadwood also arranged concerts for him; among those attending were Thackeray and the singer Jenny Lind. Chopin was also sought after for piano lessons, for which he charged the high fee of one guinea (£1.05 in present British currency) per hour, and for private recitals for which the fee was 20 guineas. At a concert on 7 July he shared the platform with Viardot, who sang arrangements of some of his mazurkas to Spanish texts.

Question: What did Broadway provide for Chopin?
Ans: a grand piano.


Here is a question about this article: Short-term memory is supported by transient patterns of neuronal communication, dependent on regions of the frontal lobe (especially dorsolateral prefrontal cortex) and the parietal lobe. Long-term memory, on the other hand, is maintained by more stable and permanent changes in neural connections widely spread throughout the brain. The hippocampus is essential (for learning new information) to the consolidation of information from short-term to long-term memory, although it does not seem to store information itself. Without the hippocampus, new memories are unable to be stored into long-term memory, as learned from patient Henry Molaison after removal of both his hippocampi, and there will be a very short attention span. Furthermore, it may be involved in changing neural connections for a period of three months or more after the initial learning.
What is the answer to this question: If the hippocampus doesn't store information what does it do?
****
So... may be involved in changing neural connections for a period of three months or more after the initial learning.


Article: London i/ˈlʌndən/ is the capital and most populous city of England and the United Kingdom. Standing on the River Thames in the south eastern part of the island of Great Britain, London has been a major settlement for two millennia. It was founded by the Romans, who named it Londinium. London's ancient core, the City of London, largely retains its 1.12-square-mile (2.9 km2) medieval boundaries and in 2011 had a resident population of 7,375, making it the smallest city in England. Since at least the 19th century, the term London has also referred to the metropolis developed around this core. The bulk of this conurbation forms Greater London,[note 1] a region of England governed by the Mayor of London and the London Assembly.[note 2] The conurbation also covers two English counties: the small district of the City of London and the county of Greater London. The latter constitutes the vast majority of London, though historically it was split between Middlesex (a now abolished county), Essex, Surrey, Kent and Hertfordshire.

Question: What part of London constitutes the bulk of the city?
Ans:
county of Greater London
