In the early 20th century, many Europeans (particularly Spaniards and Italians but also thousands from Central Europe) immigrated to the city. In 1908, 30% of the city's population of 300,000 was foreign-born. In that decade the city expanded quickly: new neighbourhoods were created and many separate settlements were annexed to the city, among which were the Villa del Cerro, Pocitos, the Prado and Villa Colon. The Rodo Park and the Estadio Gran Parque Central were also established, which served as poles of urban development.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): The Rodo Park and the Estadio Gran Parque Central serves as poles of what?
Ah, so.. urban development

In the United States, new pharmaceutical products must be approved by the Food and Drug Administration (FDA) as being both safe and effective. This process generally involves submission of an Investigational New Drug filing with sufficient pre-clinical data to support proceeding with human trials. Following IND approval, three phases of progressively larger human clinical trials may be conducted. Phase I generally studies toxicity using healthy volunteers. Phase II can include pharmacokinetics and dosing in patients, and Phase III is a very large study of efficacy in the intended patient population. Following the successful completion of phase III testing, a New Drug Application is submitted to the FDA. The FDA review the data and if the product is seen as having a positive benefit-risk assessment, approval to market the product in the US is granted.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What type of risk assessment results in approving the drug to go on the market?
Ah, so.. positive benefit-risk

One boarding house, College, is reserved for seventy King's Scholars, who attend Eton on scholarships provided by the original foundation and awarded by examination each year; King's Scholars pay up to 90% of full fees, depending on their means. Of the other pupils, up to a third receive some kind of bursary or scholarship. The name "King's Scholars" is because the school was founded by King Henry VI in 1440. The original School consisted of the seventy Scholars (together with some Commensals) and the Scholars were educated and boarded at the foundation's expense.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In 1440 where did commoners attending Eton stay?
Ah, so..
unanswerable
