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.

Input: Consider Input: Passage: Government efforts to lower subsidies to unprofitable enterprises and to shrink the money supply caused the semi-official exchange rate for the Cuban peso to move from a peak of 120 to the dollar in the summer of 1994 to 21 to the dollar by year-end 1999. The drop in GDP apparently halted in 1994, when Cuba reported 0.7% growth, followed by increases of 2.5% in 1995 and 7.8% in 1996. Growth slowed again in 1997 and 1998 to 2.5% and 1.2% respectively. One of the key reasons given was the failure to notice that sugar production had become uneconomic. Reflecting on the Special period Cuban president Fidel Castro later admitted that many mistakes had been made, "The country had many economists and it is not my intention to criticize them, but I would like to ask why we hadn't discovered earlier that maintaining our levels of sugar production would be impossible. The Soviet Union had collapsed, oil was costing $40 a barrel, sugar prices were at basement levels, so why did we not rationalize the industry?" Living conditions in 1999 remained well below the 1989 level.
Question: Where year was the Cuban peso exchange rate higher, 1994 or 1999?

Output: date

Input: Consider Input: Passage: Coming off their easy home win over the Rams, the Ravens flew to Ralph Wilson Stadium for a Week 7 duel with the Buffalo Bills. This game would be notable for RB Willis McGahee, as he returned to Buffalo to play against his former team. Also, with McNair still out with injuries, QB Kyle Boller was given the start. In the first quarter, Baltimore trailed early as Bills kicker Rian Lindell got a 29-yard field goal for the only score of the period. In the second quarter, the Ravens continued to struggle as Lindell increased Buffalo's lead with 26-yard and a 35-yard field goal. In the third quarter, Baltimore got back into the game as McGahee ran 43 yards for a touchdown. However, the Bills responded with Lindell getting a 41-yard field goal, along with RB Marshawn Lynch getting a 1-yard TD run. In the fourth quarter, the Ravens got within striking range as Boller completed a 15-yard TD pass to WR Derrick Mason. Buffalo held on to get the win.
Question: How many yards was Derrick Mason's touchdown reception?
Output: number
