Problem: Pharmaceutical industry:

Other notable new vaccines of the period include those for measles (1962, John Franklin Enders of Children's Medical Center Boston, later refined by Maurice Hilleman at Merck), Rubella (1969, Hilleman, Merck) and mumps (1967, Hilleman, Merck) The United States incidences of rubella, congenital rubella syndrome, measles, and mumps all fell by >95% in the immediate aftermath of widespread vaccination. The first 20 years of licensed measles vaccination in the U.S. prevented an estimated 52 million cases of the disease, 17,400 cases of mental retardation, and 5,200 deaths.

How much did rubella, measles, and mumps infections drop after vaccination?

A: >95%

Problem: Inns are buildings where travellers can seek lodging and, usually, food and drink. They are typically located in the country or along a highway. In Europe, they possibly first sprang up when the Romans built a system of roads two millennia ago.[citation needed] Some inns in Europe are several centuries old. In addition to providing for the needs of travellers, inns traditionally acted as community gathering places.
About how old are the oldest inns in Europe?

Answer: several centuries

On 14 July, Iraqi army officers Abdel Karim Qasim and Abdel Salam Aref overthrew the Iraqi monarchy and, the next day, Iraqi prime minister and Nasser's chief Arab antagonist, Nuri al-Said, was killed. Nasser recognized the new government and stated that "any attack on Iraq was tantamount to an attack on the UAR". On 15 July, US marines landed in Lebanon, and British special forces in Jordan, upon the request of those countries' governments to prevent them from falling to pro-Nasser forces. Nasser felt that the revolution in Iraq left the road for pan-Arab unity unblocked. On 19 July, for the first time, he declared that he was opting for full Arab union, although he had no plan to merge Iraq with the UAR. While most members of the Iraqi Revolutionary Command Council (RCC) favored Iraqi-UAR unity, Qasim sought to keep Iraq independent and resented Nasser's large popular base in the country.
Where did US Marines land?
A: Lebanon

Context and question: German air attacks on the British Isles increased in 1915 and the AA efforts were deemed somewhat ineffective, so a Royal Navy gunnery expert, Admiral Sir Percy Scott, was appointed to make improvements, particularly an integrated AA defence for London. The air defences were expanded with more RNVR AA guns, 75 mm and 3-inch, the pom-poms being ineffective. The naval 3-inch was also adopted by the army, the QF 3 inch 20 cwt (76 mm), a new field mounting was introduced in 1916. Since most attacks were at night, searchlights were soon used, and acoustic methods of detection and locating were developed. By December 1916 there were 183 AA Sections defending Britain (most with the 3-inch), 74 with the BEF in France and 10 in the Middle East.
Air attacks headed by Germany increased in 1915 in what area?
Answer: the British Isles

Question: The Kuru kingdom was the first state-level society of the Vedic period, corresponding to the beginning of the Iron Age in northwestern India, around 1200 800 BCE, as well as with the composition of the Atharvaveda (the first Indian text to mention iron, as syama ayas, literally "black metal"). The Kuru state organized the Vedic hymns into collections, and developed the orthodox srauta ritual to uphold the social order. When the Kuru kingdom declined, the center of Vedic culture shifted to their eastern neighbours, the Panchala kingdom. The archaeological Painted Grey Ware culture, which flourished in the Haryana and western Uttar Pradesh regions of northern India from about 1100 to 600 BCE, is believed to correspond to the Kuru and Panchala kingdoms.
Is there an answer to this question: At the beginning of what age are the dates of the Kuru kingdom?

Answer: Iron Age

The other usage refers to a language that is socially subordinated to a regional or national standard language, often historically cognate or related to the standard language, but not actually derived from it. In this sense, unlike in the first usage, the standard language would not itself be considered a "dialect," as it is the dominant language in a particular state or region, whether in terms of social or political status, official status, predominance or prevalence, or all of the above. Meanwhile, the "dialects" subordinate to the standard language are generally not variations on the standard language but rather separate (but often related) languages in and of themselves. For example, most of the various regional Romance languages of Italy, often colloquially referred to as Italian "dialects," are, in fact, not actually derived from modern standard Italian, but rather evolved from Vulgar Latin separately and individually from one another and independently of standard Italian, long prior to the diffusion of a national standardized language throughout what is now Italy. These various Latin-derived regional languages are therefore, in a linguistic sense, not truly "dialects" of the standard Italian language, but are instead better defined as their own separate languages. Conversely, with the spread of standard Italian throughout Italy in the 20th century, various regional versions or varieties of standard Italian developed, generally as a mix of the national standard Italian with local regional languages and local accents. These variations on standard Italian, known as regional Italian, would more appropriately be called "dialects" in accordance with the first linguistic definition of "dialect," as they are in fact derived partially or mostly from standard Italian.
What are 19th century variations of standard Italian known as?
A:
unanswerable
