TASK DEFINITION: In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
PROBLEM: what is the last time period mentioned?, Context: From the 1987 season until the late 1990s, the most exposure the league would receive was on ESPN, which aired tape-delayed games, often well after midnight, and often edited to match the alloted time slot. The league received its first taste of wide exposure in 1998, when Arena Bowl XII was televised nationally as part of ABC's old Wide World of Sports.

SOLUTION: 1998

PROBLEM: Why did using the method Bach didn't use, gain traction?, Context: The theories surrounding equal temperament began to be put in wider practice, especially as it enabled a wider range of chromatic possibilities in hard-to-tune keyboard instruments. Although Bach did not use equal temperament, as a modern piano is generally tuned, changes in the temperaments from the meantone system, common at the time, to various temperaments that made modulation between all keys musically acceptable, made possible Bach's Well-Tempered Clavier.

SOLUTION: it enabled a wider range of chromatic possibilities in hard-to-tune keyboard instruments

PROBLEM: What was the other natural disaster besides the big storm, Context: Although the Chinese government was initially praised for its response to the quake (especially in comparison to Myanmar's ruling military junta's blockade of aid during Cyclone Nargis), it then saw an erosion in confidence over the school construction scandal.

SOLUTION:
the quake
