Input: Consider Input: Question: Which of the three reservoirs produced by the damming of the Hackensack River was built first? Passage:The damming of the Hackensack River and a tributary, the Pascack Brook, produced three reservoirs in the county, Woodcliff Lake Reservoir (which impounds one billion gallons of water), Lake Tappan (3.5 billion gallons), and Oradell Reservoir, which allows United Water to provide drinking water to 750,000 residents of northern New Jersey, mostly in Bergen and Hudson counties. The Hackensack River drains the eastern portion of the county through the New Jersey Meadowlands, a wetlands area in the southern portion of the county. The central portion is drained by the Saddle River and the western portion is drained by the Ramapo River. Both of these are tributaries of the Passaic River, which forms a section of the southwestern border of the county.

Input: Consider Input: Question: What is the definition of the Werther effect? Passage:In July 1994, two students of Taipei First Girls' High School committed suicide by charcoal-burning in a hotel in Su'ao, Yilan with a note that didn't state the reason clearly, even though that it was suspected in some mass media that they were a lesbian couple. In November 1998, a middle-aged woman in Hong Kong died by suicide using this method inside her small, sealed bedroom. She had a chemical engineering background. Hong Kong was suffering from an economic depression at the time, and suicide in general was increasing. After the details of this suicide were highly publicised by local mass media, many others killed themselves in this way (an example of the Werther effect). Within two months, charcoal-burning had become the third major suicide killer in Hong Kong. Charcoal-burning suicide accounted for 1.7% of Hong Kong suicides in 1998 and 10.1% in 1999. By 2001, it had surpassed hanging as the second most-common method of suicide in Hong Kong (second only to jumping), accounting for about 25% of all suicide deaths. The method has since spread to mainland China, Taiwan and Japan.
