[Q]: Extract the answer to the question from the following context. Question: What population increased by 77% in 20 years? Context: In recent years, the city has experienced steady population growth, and has been faced with the issue of accommodating more residents. In 2006, after growing by 4,000 citizens per year for the previous 16 years, regional planners expected the population of Seattle to grow by 200,000 people by 2040. However, former mayor Greg Nickels supported plans that would increase the population by 60%, or 350,000 people, by 2040 and worked on ways to accommodate this growth while keeping Seattle's single-family housing zoning laws. The Seattle City Council later voted to relax height limits on buildings in the greater part of Downtown, partly with the aim to increase residential density in the city centre. As a sign of increasing inner-city growth, the downtown population crested to over 60,000 in 2009, up 77% since 1990.

[Q]: Extract the answer to the question from the following context. Question: what group is mentioned second to last? Context: India rejected Chinese demands that the torch route be clear of India's 150,000-strong Tibetan exile community, by which they required a ban on congregation near the curtailed 3 km route. In response Indian officials said India was a democracy, and "a wholesale ban on protests was out of the question". Contradicting some other reports, Indian officials also refused permission to the "Olympic Holy Flame Protection Unit". The combined effect is a "rapid deterioration" of relations between India and China. Meanwhile, the Tibetan government in exile, which is based in India, has stated that it did not support the disruption of the Olympic torch relay.
