Problem: Energy:

Sunlight may be stored as gravitational potential energy after it strikes the Earth, as (for example) water evaporates from oceans and is deposited upon mountains (where, after being released at a hydroelectric dam, it can be used to drive turbines or generators to produce electricity). Sunlight also drives many weather phenomena, save those generated by volcanic events. An example of a solar-mediated weather event is a hurricane, which occurs when large unstable areas of warm ocean, heated over months, give up some of their thermal energy suddenly to power a few days of violent air movement.

This drives no weather phenomena, save those generated by volcanic events.

Problem: The Bronx contains one of the five poorest Congressional Districts in the United States, the 15th, but its wide diversity also includes affluent, upper-income and middle-income neighborhoods such as Riverdale, Fieldston, Spuyten Duyvil, Schuylerville, Pelham Bay, Pelham Gardens, Morris Park and Country Club. The Bronx, particularly the South Bronx, saw a sharp decline in population, livable housing, and the quality of life in the late 1960s and the 1970s, culminating in a wave of arson. Since then the communities have shown significant redevelopment starting in the late 1980s before picking up pace in the 1990s into today.
When did the South Bronx lose quality of life?

Answer: the late 1960s and the 1970s

The declining trend however continued into season eight, as total viewers numbers fell by 5–10% for early episodes compared to season seven, and by 9% for the finale. In season nine, Idol's six-year extended streak of perfection in the ratings was broken, when NBC's coverage of the 2010 Winter Olympics on February 17 beat Idol in the same time slot with 30.1 million viewers over Idol's 18.4 million. Nevertheless, American Idol overall finished its ninth season as the most watched TV series for the sixth year running, breaking the previous record of five consecutive seasons achieved by CBS' All in the Family and NBC's The Cosby Show.
Which television network aired the Winter Olympics in 2010? 
A: NBC
