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: 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.
Question: How did Wang Song die?

Output: span

Input: Consider Input: Passage: By the end of 1501, the rebellion was put down. The Muslims were no longer given their rights provided by the Treaty of Granada, and were given the choice of:  remain and accept baptism,  reject baptism and be enslaved or killed, or  be exiled. Given the expensive fee exacted for passage out of Spain, conversion was the only realistic option for them. Therefore, only a decade after the fall of the Emirate of Granada, the entire Muslim population of Granada had nominally become Christian. A proclamation in 1502 extended these forced conversions to the rest of the lands of Castile, even though those outside Granada had nothing to do with the rebellion. The newly converted Muslims were known as nuevos cristianos  or moriscos . Although they converted to Christianity, they maintained their existing customs, including their language, distinct names, food, dress and even some ceremonies. Many secretly practiced Islam, even as they publicly professed and practiced Christianity. In return, the Catholic rulers adopted increasingly intolerant and harsh policies in order to eradicate these characteristics. This culminated in Philip II's Pragmatica of 1 January 1567 which ordered the Moriscos to abandon their customs, clothing and language. The pragmatica triggered the Morisco revolts in 1568-1571.
Question: How many years did the Morisco revolts last?


Output: number
