question:
Passage: Jacksonville has suffered less damage from hurricanes than most other east coast cities, although the threat does exist for a direct hit by a major hurricane. The city has only received one direct hit from a hurricane since 1871; however, Jacksonville has experienced hurricane or near-hurricane conditions more than a dozen times due to storms crossing the state from the Gulf of Mexico to the Atlantic Ocean, or passing to the north or south in the Atlantic and brushing past the area. The strongest effect on Jacksonville was from Hurricane Dora in 1964, the only recorded storm to hit the First Coast with sustained hurricane-force winds. The eye crossed St. Augustine with winds that had just barely diminished to 110 mph (180 km/h), making it a strong Category 2 on the Saffir-Simpson Scale. Jacksonville also suffered damage from 2008's Tropical Storm Fay which crisscrossed the state, bringing parts of Jacksonville under darkness for four days. Similarly, four years prior to this, Jacksonville was inundated by Hurricane Frances and Hurricane Jeanne, which made landfall south of the area. These tropical cyclones were the costliest indirect hits to Jacksonville. Hurricane Floyd in 1999 caused damage mainly to Jacksonville Beach. During Floyd, the Jacksonville Beach pier was severely damaged, and later demolished. The rebuilt pier was later damaged by Fay, but not destroyed. Tropical Storm Bonnie would cause minor damage in 2004, spawning a minor tornado in the process. On May 28, 2012, Jacksonville was hit by Tropical Storm Beryl, packing winds up to 70 miles per hour (113 km/h) which made landfall near Jacksonville Beach. Question: In what year did a tropical storm cause a four day loss of power to Jacksonville?
answer:
2008


question:
Passage: Despite their soft, gelatinous bodies, fossils thought to represent ctenophores, apparently with no tentacles but many more comb-rows than modern forms, have been found in lagerstätten as far back as the early Cambrian, about 515 million years ago. The position of the ctenophores in the evolutionary family tree of animals has long been debated, and the majority view at present, based on molecular phylogenetics, is that cnidarians and bilaterians are more closely related to each other than either is to ctenophores. A recent molecular phylogenetics analysis concluded that the common ancestor of all modern ctenophores was cydippid-like, and that all the modern groups appeared relatively recently, probably after the Cretaceous–Paleogene extinction event 66 million years ago. Evidence accumulating since the 1980s indicates that the 'cydippids' are not monophyletic, in other words do not include all and only the descendants of a single common ancestor, because all the other traditional ctenophore groups are descendants of various cydippids. Question: Fossils found that were believed to be ctenophores were how old?
answer:
515 million years


question:
Passage: In particular, this norm gets smaller when a number is multiplied by p, in sharp contrast to the usual absolute value (also referred to as the infinite prime). While completing Q (roughly, filling the gaps) with respect to the absolute value yields the field of real numbers, completing with respect to the p-adic norm |−|p yields the field of p-adic numbers. These are essentially all possible ways to complete Q, by Ostrowski's theorem. Certain arithmetic questions related to Q or more general global fields may be transferred back and forth to the completed (or local) fields. This local-global principle again underlines the importance of primes to number theory. Question: Completing Q with respect to what will produce the field of real numbers?
answer:
the absolute value
