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.

Passage: Hoping to rebound from their divisional home loss to the Colts, the Texans flew to the Georgia Dome for an interconference battle with the winless Atlanta Falcons, where QB Matt Schaub would fight against his former team. In the first quarter, Houston trailed early as Falcons kicker Morten Andersen nailed a 28-yard field goal.  The Texans managed to take the lead with Schaub completing a 35-yard TD pass to WR Andr&#233; Davis.  However, Atlanta regained the lead with QB Joey Harrington completing a 5-yard TD pass to WR Michael Jenkins  In the second quarter, Houston's current woes continued with Harrington and Jenkins hooking up with each other again as 7-yard TD pass, along with Andersen kicking a 22-yard field goal.  The Texans got their only score of the period with kicker Kris Brown nailing a 42-yard field goal. In the third quarter, Houston kept closer with a 37-yard field goal, but the Falcons eventually responded with Andersen kicking a 36-yard field goal.  In the fourth quarter, the Texans again crept closer with Brown getting a 19-yard field.  Yet again, Atlanta replied with Andersen kicking a 46-yard field goal.  Afterwards, the Falcons held on to get their first win of the year.
