input question: Question: "What has Antarctica's status been since 1959?" Context: "New claims on Antarctica have been suspended since 1959 although Norway in 2015 formally defined Queen Maud Land as including the unclaimed area between it and the South Pole. Antarctica's status is regulated by the 1959 Antarctic Treaty and other related agreements, collectively called the Antarctic Treaty System. Antarctica is defined as all land and ice shelves south of 60 S for the purposes of the Treaty System. The treaty was signed by twelve countries including the Soviet Union (and later Russia), the United Kingdom, Argentina, Chile, Australia, and the United States. It set aside Antarctica as a scientific preserve, established freedom of scientific investigation and environmental protection, and banned military activity on Antarctica. This was the first arms control agreement established during the Cold War." Answer:???
output answer: unclaimed

input question: Question: "What are stems and branches composed of?" Context: "In the dicotyledons, the bundles in the very young stem are arranged in an open ring, separating a central pith from an outer cortex. In each bundle, separating the xylem and phloem, is a layer of meristem or active formative tissue known as cambium. By the formation of a layer of cambium between the bundles (interfascicular cambium), a complete ring is formed, and a regular periodical increase in thickness results from the development of xylem on the inside and phloem on the outside. The soft phloem becomes crushed, but the hard wood persists and forms the bulk of the stem and branches of the woody perennial. Owing to differences in the character of the elements produced at the beginning and end of the season, the wood is marked out in transverse section into concentric rings, one for each season of growth, called annual rings." Answer:???
output answer: hard wood

input question: Question: "How much of a cell wall is lingnin?" Context: "Wood is a heterogeneous, hygroscopic, cellular and anisotropic material. It consists of cells, and the cell walls are composed of micro-fibrils of cellulose (40% 50%) and hemicellulose (15% 25%) impregnated with lignin (15% 30%)." Answer:???

The population density is 1.4 persons per hectare, which can be compared to 2.07 persons per hectare for the South West region. Within the county, population density ranges 0.5 in West Somerset to 2.2 persons per hectare in Taunton Deane. The percentage of the population who are economically active is higher than the regional and national average, and the unemployment rate is lower than the regional and national average." Answer:???
