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.

Passage: Sources do not agree on a precise number of deaths from the war because of a lack of body counts for confirmation. The number of Japanese Army dead in combat or died of wounds is put at around 59,000 with around 27,000 additional casualties from disease, and between 6,000 and 12,000 wounded. Estimates of Russian Army dead range from around 34,000 to around 53,000 men with a further 9,000 - 19,000 died of disease and around 75,000 captured. The total number of dead for both sides is generally stated as around 130,000 to 170,000. China suffered 20,000 civilian deaths, and financially the loss amounted to over 69 million taels' worth of silver. During many of the battles at sea, several thousand soldiers being transported drowned after their ships went down. There was no consensus about what to do with transported soldiers at sea, and as a result, many of the ships failed or refused to rescue soldiers that were left shipwrecked. This led to the creation of the second Geneva Convention in 1906, which gave protection and care for shipwrecked soldiers in armed conflict.
Question: How many more, considering only the low range of estimates, of Japanese Army dead in combat or died of wounds than Russian Army?

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.
