Question:
The United States Navy (USN) hoped to use the V-1710 in its rigid airships USS Akron (ZRS-4) and USS Macon (ZRS-5), but both were equipped with German-built Maybach VL-2 engines as the V-1710 was still in testing when the Macon was lost in February 1935 (the Akron having been lost in April 1933). The USAAC purchased its first V-1710 in December 1932. The Great Depression slowed development, and it was not until December 14, 1936 that the engine next flew in the Consolidated XA-11A testbed. The V-1710-C6 successfully completed the USAAC 150 hour Type certificate on April 23, 1937 at , the first engine of any type to do so. The engine was then offered to aircraft manufacturers where it powered the prototype Curtiss XP-37s. All entrants in the new pursuit competition were designed around it, powering the Lockheed P-38, Bell P-39 and Curtiss P-40. When war British Purchasing Commission asked North American Aviation to build the P-40 under license, NAA instead proposed their own improved aircraft design, using the V-1710 in their North American P-51 Mustang.

Which airship was lost later, the Akron or the Macon?

Answer:
Macon

Question:
The Chargers opened the season on September 11, 2006, with a 27-0 victory over the division rival Oakland Raiders. This second game of a Monday Night Football doubleheader marked the first time the Chargers had shutout the Raiders since a 44-0 win in 1961. LaDainian Tomlinson led the Chargers with 31 carries for 131 yards, while Philip Rivers, in his debut as an NFL starting quarterback, completed 8 of 11 pass attempts for 108 yards with one touchdown pass and no interceptions. The Chargers' defense stifled the Raiders' running game, holding Raiders RB Lamont Jordan to 20 yards on 10 carries, and recorded 9 quarterback sacks against Raiders QBs Aaron Brooks and Andrew Walter. Three of those sacks belonged to second-year LB Shawne Merriman. With the win, the Chargers extended their winning streak against Oakland to six games, while head coach Marty Schottenheimer improved his head coaching record against the Raiders to 26-7. Schottenheimer also earned his 187th career victory, passing Chuck Knox to become the seventh-winning-est head coach in NFL history. That shutout also marked the second time ever that Oakland had been shut out in their own stadium, the second being the Denver Broncos and the third being the St. Louis Rams as the Chargers picked up their 6th straight win over the Raiders and started their season 1-0.

how many career victories had schottenheimer had?

Answer:
187

Following their Monday Night loss to the Raiders, the Broncos remained on home turf to face the Cincinnati Bengals. The Broncos took the lead in the first quarter, with a 1-yard touchdown run by running back Willis McGahee. The Bengals got on the board in the second quarter, with a 45-yard field goal by placekicker Mike Nugent. The Broncos responded, with a 34-yard field goal by placekicker Matt Prater just before halftime.

In the fourth quarter, the Broncos once again increased their lead, with a 52-yard touchdown pass from Orton to Decker, but the Bengals responded, with a 5-yard touchdown pass from Dalton to wide receiver A. J. Green. The Broncos' defense prevented any more scoring.

How many successful field goals did Nugent kick?

Answer:
2

Question:
Croatian air pollution levels reflect the drop in industrial production recorded in 1991 at the onset of the Croatian War of Independencepre-war emission levels were only reached in 1997. The use of Hydrodesulfurization fuels has led to a 25% reduction of sulphur dioxide emissions between 1997 and 2004, and a further 7.2% drop by 2007. The rise in NOx emissions halted in 2007 and reversed in 2008. The use of unleaded petrol reduced emissions of lead into the atmosphere by 91.5% between 1997 and 2004. Air quality measurements indicate that the air in rural areas is essentially clean, and in urban centres it generally complies with legal requirements. The most significant sources of greenhouse gas (GHG) emissions in Croatia are energy production (72%), industry (13%) and agriculture (11%). The average annual increase of GHG emissions is 3%, remaining within the Kyoto Protocol limits. Between 1990 and 2007, the use of Ozone depletion was reduced by 92%; their use is expected to be abolished by 2015.

How many years did it take for the reduction of sulphur dioxide emissions to drop by 25%?

Answer:
7
