Passage: Coming off a road loss to the Steelers, the Saints went home for an interconference fight with the Cincinnati Bengals.  In the first quarter, Cincinnati struck first with quarterback Carson Palmer completing a 41-yard touchdown pass to WR Chad Johnson.  Afterwards, New Orleans responded with quarterback Drew Brees completing a 72-yard touchdown pass to WR Joe Horn.  In the second quarter, the Bengals took the lead with kicker Shayne Graham getting a 21-yard field goal for the only score of the period.  After a scoreless third quarter, kicker John Carney began the fourth quarter with 24-yard field goal.  However, things went downhill with Cincinnati's most dominant part of the game.  Palmer would complete a 60-yard touchdown pass and a 4-yard touchdown pass to Chad, while rookie DB Ethan Kilmer returned an interception 52 yards for a touchdown.  Afterwards, New Orleans could only muster a 27-yard touchdown pass from Brees to WR Terrance Copper.  With the loss, the Saints fell to 6-4. 
Question: How many yards was Palmer's shortest touchdown pass to Johnson?

question:
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 
answer:
{'day': '', 'month': '', 'year': '1497'}.
