Input: Read this: Reptiles such as adders and vipers live up to the snow line; because they cannot bear the cold temperatures they hibernate underground and soak up the warmth on rocky ledges. The high-altitude Alpine salamanders have adapted to living above the snow line by giving birth to fully developed young rather than laying eggs. Brown trout can be found in the streams up to the snow line. Molluscs such as the wood snail live up the snow line. Popularly gathered as food, the snails are now protected.
Question: Why do reptiles only live up to the snow line?

Output: they cannot bear the cold temperatures


Input: Read this: The library is based at two public sites: the Reading Room at the RIBA's headquarters, 66 Portland Place, London; and the RIBA Architecture Study Rooms in the Henry Cole Wing of the V&A. The Reading Room, designed by the building's architect George Grey Wornum and his wife Miriam, retains its original 1934 Art Deco interior with open bookshelves, original furniture and double-height central space. The study rooms, opened in 2004, were designed by Wright & Wright. The library is funded entirely by the RIBA but it is open to the public without charge. It operates a free education programme aimed at students, education groups and families, and an information service for RIBA members and the public through the RIBA Information Centre.
Question: Who is not meant to benefit from the teaching provided by the RIBA library?

Output: unanswerable


Input: Read this: The considerable spending did not lead to more growth and did not benefit the poor. Much of the increased spending has gone to current expenditures related to wages, transfers, and subsidies. The wage bill today constitutes over 15% of GDP and 55% of total public spending; these are some of the highest levels on the African continent. The recent rapid growth in SACU revenues has, however, reversed the fiscal situation, and a sizeable surplus was recorded since 2006. SACU revenues today account for over 60% of total government revenues. On the positive side, the external debt burden has declined markedly over the last 20 years, and domestic debt is almost negligible; external debt as a percent of GDP was less than 20% in 2006.
Question: What has happened to debt external onus  in Swaziland in the past two decades?

Output: declined markedly
