This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning). 
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.

Q: Passage: September 18, 2011 at Sports Authority Field at Mile High, Denver, Colorado The Bengals came into the game losing the previous two games against the Denver Broncos. The Bengals have not won at Denver since 1975. Dalton started the game, despite missing practices and not being cleared until Friday because of his wrist injury. Paid attendance of 73,281 was the highest amount of any games the Bengals played in 2011. The first score of the game happened in the first quarter when RB Willis McGahee ran one yard for a touchdown. Both teams scored a field goal in the second quarter to make the game 10-3 going into halftime. Denver QB Kyle Orton threw two touchdown passes to WR Eric Decker&#8212;one in the third quarter and one in the fourth quarter. With two minutes left in the game, the Bengals were down 24-22 and tried to score to win the game. The Bengals reached midfield, but the Broncos' defense stopped the Bengals and a fourth-and-nineteen occurred. Dalton threw the ball away, and a turnover on downs happened. Dalton's passer rating of 107.0 was a franchise best by a rookie, and WR Jerome Simpson had a career-high 136 receiving yards. WR Jordan Shipley torn his anterior cruciate ligament this game, which ended his 2011 season.

A: How many games in a row was this loss for the Bengals?

Q: Passage: In 1993, Porsche Motorsports at Weissach briefly produced a Turbocharger 968 Turbo S, a fairly odd naming choice for Porsche which usually reserves the added "S" moniker for models that have been tuned for more power over a "lesser" counterpart, such as with the 911 Turbo. The 968 Turbo S shared the same body and interior as the Club Sport and visually can be identified by the NACA bonnet hood scoops, adjustable rear wing and deeper front spoiler. Powered by a large 8 valve SOHC cylinder head (944 Turbo S) with a 3.0 L 944S2 style engine block. Tests conducted in 1993 produced a 0 to  time of 4.7 seconds and a top speed of , performance comparable to the much newer Porsche 996 911. It generated  at 5,600 rpm with a maximum torque of  at 3,000 rpm. Only 16 were produced in total and only for sale in mainland Europe.

A:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
