Definition: 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.
Input: Passage: Hoping to rebound from their loss to the Steelers, the Ravens flew to Reliant Stadium for a Week 14 Monday night duel with the Houston Texans. Baltimore delivered the game's opening strike with a 1-yard touchdown run from running back Willis McGahee. The Ravens added onto their lead in the second quarter as quarterback Joe Flacco found wide receiver Derrick Mason on a 9-yard and a 26-yard touchdown pass. The Texans answered with quarterback Matt Schaub completing a 46-yard touchdown pass to wide receiver Andre Johnson. Baltimore struck back to open the third quarter with rookie wide receiver David Reed returning the second half's opening kickoff 103yards for a touchdown. Houston responded with kicker Neil Rackers making a 24-yard and a 42-yard field goal. The Texans tied the game in the fourth quarter as Schaub completed a 7-yard touchdown pass to wide receiver Jacoby Jones, a 5-yard touchdown pass to Johnson, and a successful two-point conversion pass to Jones. In overtime, the Ravens got the win as cornerback Josh Wilson returned a 12-yard interception for a touchdown.
Output:
How many defensive touchdowns were scored?
