In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
One example: what is the first event mentioned?, Context: The Russian Revolution is the series of revolutions in Russia in 1917, which destroyed the Tsarist autocracy and led to the creation of the Soviet Union. Following the abdication of Nicholas II of Russia, the Russian Provisional Government was established. In October 1917, a red faction revolution occurred in which the Red Guard, armed groups of workers and deserting soldiers directed by the Bolshevik Party, seized control of Saint Petersburg (then known as Petrograd) and began an immediate armed takeover of cities and villages throughout the former Russian Empire.
Solution is here: Russian Revolution
Explanation: This is a good example, and the Russian Revolution is the first event mentioned.

Now, solve this: What did the report measure in various cities?, Context: In a report, published in early February 2007 by the Ear Institute at the University College London, and Widex, a Danish hearing aid manufacturer, Newcastle was named as the noisiest city in the whole of the UK, with an average level of 80.4 decibels. The report claimed that these noise levels would have a negative long-term impact on the health of the city's residents. The report was criticized, however, for attaching too much weight to readings at arbitrarily selected locations, which in Newcastle's case included a motorway underpass without pedestrian access.
Solution:
noise levels
