Ex Input:
Who, it is assumed, was President of the United States at the time of the events which take place in the article?, Context: Whittaker was unsuited for the role and soon retired. Stewart and Harlan were conservative Republicans, while Brennan was a Democrat who became a leading voice for liberalism. In selecting a Chief Justice, Eisenhower looked for an experienced jurist who could appeal to liberals in the party as well as law-and-order conservatives, noting privately that Warren "represents the kind of political, economic, and social thinking that I believe we need on the Supreme Court ... He has a national name for integrity, uprightness, and courage that, again, I believe we need on the Court". In the next few years Warren led the Court in a series of liberal decisions that revolutionized the role of the Court.

Ex Output:
Eisenhower

What was the main focus, in relation to the head of cabinet of Kenya of a radical divergence from the previous set of guidelines for a country that was bounced off the legislators in Kenya?, Context: A constitutional change was considered that would eliminate the position of Prime Minister and simultaneously reduce the powers of the President. A referendum to vote on the proposed constitution was held on 4 August 2010, and the new constitution passed by a wide margin. Among other things, the new constitution delegates more power to local governments and gives Kenyans a bill of rights. It was promulgated on 27 August 2010 at a euphoric ceremony in Nairobi's Uhuru Park, accompanied by a 21-gun salute. The event was attended by various African leaders and praised by the international community. As of that day, the new constitution heralding the Second Republic came into force.

eliminate the position of Prime Minister
