This task involves annotating the answer type to a given question that involve some kind of complex reasoning (including numerical reasoning). Note that the questions require looking at more than one part of the passage to answer. There are 3 possible answer types (i) spans, (ii) numbers and (iii) dates. If the answer can be found in the passage, label it as "span". If the answer is a number, label as "number". Similarly, label "date" if you think the answer to the given question is a date.

Example Input: Passage: Still searching for their first win of the season, the Bengals went home for a Week 7 AFC North duel with the Pittsburgh Steelers.  With Carson Palmer still out with a sore elbow, QB Ryan Fitzpatrick was given the start. In the first quarter, Cincinnati trailed early as Steelers QB Ben Roethlisberger completed a 2-yard TD pass to RB Mewelde Moore, along with kicker Jeff Reed getting a 21-yard field goal.  In the second quarter, the Bengals answered with Fitzpatrick completing a 5-yard TD pass to WR Chad Ocho Cinco.  In the third quarter, Pittsburgh responded with Moore getting a 13-yard TD run.  Cincinnati would respond with kicker Dave Rayner nailing a 26-yard field goal.  However, in the fourth quarter, the Steelers pulled away with Roethlisberger completing a 50-yard TD pass to WR Nate Washington, Moore getting a 2-yard TD run, and QB Byron Leftwich completing a 16-yard TD pass to WR Hines Ward.  Earlier in the game, Ward destroyed Bengals linebacker Keith Rivers with a vicious legal hit, breaking Rivers' jaw. With the loss, Cincinnati dropped to 0-7.  The team's first such start since 2002.
Question: how many yards did Roethlisberger complete?

Example Input: Passage: The Second Goryeo-Khitan War was an 11th-century conflict between the kingdom of Goryeo and the Liao dynasty  near what is now the border between China and North Korea. It was the second of the Goryeo-Khitan Wars, with the First Goryeo-Khitan War occurring in 993, the second in 1010, and the third in 1018. When King Seongjong died in 997, Liao invested his successor Wang Song as king of Goryeo . In 1009, he was assassinated by the forces of the general Gang Jo. Using it as a pretext, the Liao attacked Goryeo in the next year. They lost the first battle but won the second one, and Gang Jo was captured and killed. The Liao occupied and burnt the Goryeo capital Kaesong. The Khitan withdrew after Goryeo reaffirmed its tributary relationship with the Khitan.
