A "span" answer is a continuous phrase taken directly from the passage or question. You can directly copy-paste the text from the passage or the question for span type answers. If you find multiple spans, please add them all as a comma separated list. Please restrict each span to five words. A "number" type answer can include a digit specifying an actual value.

[EX Q]: Passage: Following Henry VIII of England of England and his infamous "Great Debasement" program that began 1526, the Spanish King Philip III tried to cement his Spanish legacy through changes in coinage strategy. Previously, Spanish Kings (at least from 1471) issued a largely copper fractional coinage called blancas, with a nominal money-of-account value of 0.5 maravedí, but with a very small amount of silver to convince the public that it was indeed precious-metal "money". The blanca issued in 1471 had a silver fineness of 10 grains or 3.47% (weighing 1.107g). In 1497, that fineness was reduced to 7 grains (2.43% fine); in 1552, to 5.5 grains (1.909% fine); in 1566, to 4 grains (1.39% fine). By the start of the 17th century, inflation took hold of Spain as the gap between nominal and silver-based prices dramatically shifted. The purely copper coinage had done its damage to Spain. The difference between the silver- and vellon-based price indexes in Spain showed that the purely copper coinage other European countries used made up a much smaller proportion of the total coined money supply (something the Spanish Kings had overlooked and Malestroit was able to pinpoint). 
Question: Which year was the blanca issued with a lower silver fineness, 1471 or 1497? 
Answer type: Date 
[EX A]: {'day': '', 'month': '', 'year': '1497'}.

[EX Q]: Passage: Hoping to rebound from their first loss of the season, the Titans flew to Ford Field for a Week 13 Thanksgiving game against the winless Detroit Lions.

The Titans would answer with Johnson getting a 58-yard TD run, along with DE Dave Ball returning an interception 15 yards for a touchdown. In the second quarter, Tennessee increased their lead with RB LenDale White getting a 6-yard and a 2-yard TD run. Detroit would reply with QB Daunte Culpepper completing a 2-yard TD pass to TE Michael Gaines. In the third quarter, kicker Rob Bironas would kick field goals of 41 and 49 yards to put the Titans up by 31, and in the fourth quarter, he would nail field goals of 45 and 43 yards to put the Titans up for good.
