Example Input: If California truly leads the nation, we can elect a black woman to the US Senate. Here in California, it's been a blockbuster week in politics : Barbara Boxer is finally stepping down as perma-Senator after over 20 years ; former San Francisco mayor and current lieutenant governor Gavin Newsom is running for governor ; and attorney general Kamala Harris gunning for Boxer's soon-to-be- vacated seat . Why does it matter? There' s certainly something compelling about Harris' daring bid for US Senate : there are only one in five senators are female in this Congress ; and there are only two black Senators currently (Cory Booker of New Jersey and Tim Scott from South Carolina) . If Harris won , she not only would contribute to the growing number of women in power, but having three actual black senators at one time would make history because, to date, two is the best we've been able to achieve as a nation . In America's entire history, only eight black people have ever been senators and of those, only half were actually elected, rather than appointed . Yet African-Americans make up about 13% of the population, according to the 2013 census . True proportional representation would see black senators in the double digits in Congress . California has outsized importance in the US economy : on its own, it is the world's eighth-largest economy, just behind booming Brazil but ahead of Russia and Italy . California's contributions are one of the chief reasons the US remains the world's biggest economy ... and a black woman is poised to be one of the most nationally influential politicians in the state . California's internal public policy tussles - and its standard more-liberal- than-the-nation solutions - often help lead the rest of the nation and the world forward, be it on pollution standards, minimum wage increases, medical marijuana legalization, organic produce certification, healthcare access for the uninsured, public-private technology innovation such as iHubs and tax breaks that encourage local production of zero-emission Teslas, same sex marriage and wetlands protections such as the CA Coastal Act of 1976 . California's politicians can bring to Washington the ability to combine strong, safe regulatory experience with a booming economy and environmental protections, offering a compelling counter-point to Republicans who argue otherwise . And ,  with the exception of Jerry Brown's first stint as governor from 1975-1983, California internal top politics has been tended to be dominated by southern California figures like Ronald Reagan and Arnold Schwarzenegger - but Harris (and Newsom) are both northern California people through and through . Instead of Hollywood values and priorities holding sway in the state, northern California's tech-powered financial and cultural strength may finally have a chance to drive the state's politics . And while Boxer, her fellow senator Dianne Feinstein and House minority leader Nancy Pelosi all hail from northern California, they spend much of their time in Washington DC  - so Harris's move to DC will provide us with a new generation of representatives steeped in the area's emerging tech-focused culture . While I believe California has much to gain from politicians like Newsom and Harris who see their work as largely cooperative and people-focused- as opposed to the ideological culture warriors who normally represent us in national policy debates - there's a long road ahead for each . Harris, for instance, may have to contend with billionaire Tom Steyer and former Los Angeles mayor Antonio Villaraigosa in a Democratic primary (and Villaraigosa would make history of his own) . But Harris is likely to have a lot of support behind her and  - being young, at 50 - a run now for Senate still leaves the door open to run for governor 10 or 20 years down the road . After all ,  stranger things have happened in CA politics : who would have thought that B-list actor Ronald Reagan would rise from California to become the GOP's iconic president , or that Jerry Brown, now 76-years-old, would become governor again after over 30 years?
Example Output: Barbara Boxer is finally stepping down as perma-Senator after over 20 years attorney general Kamala Harris gunning for Boxer's soon-to-be- vacated seat

Example Input: We are the last generation that can fight climate change. We have a duty to act. This year the UN marks its 70th anniversary . Sadly, there is little time for reflection or celebration . More pressing are the competing demands and challenges fuelled by an upsurge in conflict, disease and human suffering . These compel the international community to step up and provide the leadership needed to tackle them . Ebola continues to plague west Africa . For some of the affected countries, struggling to overcome the effects of bitter civil war, the outbreak has been a major setback for development . We are beginning to see some improvements . During my visit to the region in December, I was deeply moved by the efforts of local Ebola responders and health workers from across Africa and the world . But rebuilding shattered lives and economies will require significantly more resources and long-term commitment . As conflicts raged and extremism rose , 2014 pushed the UN's humanitarian, peacekeeping and diplomatic efforts to the limit . More than 100 million people needed assistance . An unprecedented number of UN troops and police are deployed in highly volatile security environments . The elimination of Syria's chemical weapons programme was a major achievement , but the conflict continues to inflict immense suffering and will soon enter its fifth year . As bitter winter conditions set in , millions of refugees are in need of life-saving humanitarian assistance . The presence of thousands of foreign terrorist fighters there and in Iraq has added a further volatile dimension . Groups responsible for atrocities have capitalised on a legacy of atrocious governance towards disenfranchised populations . Our response to brutality and extremism cannot be limited to military action, important as it is . We must address the conditions that give rise to such poison in the first place . In the same vein, those conducting military actions against terrorists must be sure that such efforts fully observe human rights . As we have seen time and again , failure to do so can end up serving as a recruiting agent for terrorists . Elsewhere, the recent appalling terrorist attacks in Paris show how vulnerable any society can be . Countries in Europe and elsewhere have witnessed a deeply worrying escalation of tensions between communities and within societies . Giving in to hatred and sowing division only guarantees a spiral of violence- precisely what terrorists seek . We must not fall into that trap . Addressing discord in a manner that solves, rather than multiplies, the problem may be the greatest test our human family faces in the 21st century . There is a long list of other hot-spots- stretching from Nigeria to Yemen, from the rise in fighting in Darfur to the transition in Afghanistan . Conflict in Ukraine has endangered security and stability in Europe, and reanimated the ghosts of the cold war . Israelis and Palestinians must ease the explosive situation in Gaza and the West Bank, and move away from confrontation and towards a negotiated settlement . But in a year marked by turmoil, UN member states have also proposed an initial draft set of sustainable development goals that will guide anti- poverty efforts for the next generation . Further negotiations will begin this month and culminate at a special summit in New York in September with the adoption of a development agenda that can help tackle inequality, empower women and girls, and promote shared prosperity . Climate action took on significant momentum with major announcements by the EU, the US and China, and a successful climate conference in Lima, Peru , that kept complex negotiations on track . We must aim high: for the adoption of an ambitious and universal agreement in Paris in December to keep the rise in global temperatures below the dangerous threshold of 2C . Ours is the first generation that can end poverty, and the last that can take steps to avoid the worst impacts of climate change . In this 70th anniversary year in which we renew our commitment to the goals and principles of the UN charter, the international community must rise to the moment .
Example Output: Ours is the first generation that can end poverty, and the last that can take steps to avoid the worst impacts of climate change

Example Input: Five reasons why European Central Bank's QE won't save continent's dying economies. The European Central Bank has just announced a EUR60 billion ($69 billion) monthly government bond buying program--Quantitative Easing -- but that won't do much for the moribund continental economy . Central banks can print money to purchase government bonds to push up prices and lower interest rates on those assets and competing debt, such as corporate bonds and bank loans . In the United States, the Federal Reserve also bought billions in federally-sponsored mortgage-backed securities, such as those issued by Fannie Mae . The aim is to encourage more borrowing by businesses and homebuyers-- stimulus spending financed by running the printing press . The Fed enjoyed some success boosting U.S  growth , but here are five reasons why QE won't work for the ECB . 1 \. Eurozone Is Not a Country . The European Union does not have a large budget and issues few euro-denominated bonds the ECB could purchase . Instead, the ECB will have to purchase individual country debt -- it is as if the Fed had to purchase a basket of bonds issued by California, Iowa and other states . Markets for European bonds--both sovereign and corporate--and bank lending are highly fragmented along country lines . Consequently ,  it is unlikely that QE will have much effect on banks' willingness to make new business loans in places buffeted by the financial crisis, like Spain and Greece . 2 \. EU Has No Fannie Mae . QE seems to work best when central banks inject capital directly into specific markets . The Fed purchased mortgage-backed securities that significantly lowered interest rates on mortgages across America . Housing prices recovered much of the value lost during the financial crisis , and new home construction rebounded . The EU has no analog to Fannie Mae and Freddie Mac , and the ECB cannot readily purchase mortgage-backed securities to boost the European housing sector . 3 \. Fiscal Policy Is Pulling in the Opposite Direction . Europe's largest economy, Germany, recently accomplished a balanced budget for the first time since 1969 , and austerity programs intended to restore solvency have forced massive government spending cuts and tax increases in Spain, Greece and other Mediterranean states . Those spending cuts-- though essential to sorely needed structural reforms-- will undercut the effects of any increased bank lending ECB bond purchase may induce . With unemployment hovering at about 25 percent in Spain and Greece, and 13 percent in Italy, banks will remain skeptical that lending to expand businesses will do much to create bigger markets for what they sell . 4 \. QE Does Little to Fix Euro-Imposed Dysfunctions . Although structural reforms could make Greece, Italy and other high unemployment economies more attractive places to build factories and establish businesses in the long run, governments in Athens, Rome and other capitals face voters who need jobs now . And the cost of labor--though perhaps gradually falling--in these countries will remain too high to attract investment for many years . If Mediterranean countries still had their own currencies , those could let their currencies fall in value relative to those of northern European states . That would re-price labor to attract investment and jobs . But the single currency, the euro, deprives them of that lever . 5 \. Absence of Pan European Institutions . Though the Europeans have a single currency, they lack common education standards and language that gives the United States a more or less single labor market . In the absence of currency devaluation to re-price Mediterranean labor, Greeks, Italians and Spaniards cannot migrate to Germany where unemployment is only 5 percent, with the same ease that Americans have migrated to South Dakota and Texas to participate in the oil boom . In the end, the EU and ECB lacks what the Fed enjoys--the punch of a national government that ran large deficits to augment its efforts to pull the U.S  economy out of recession and national credit, housing and labor markets that made monetary policies--like QE--reasonably effective .
