Input: Article: The death penalty is sought and applied more often in some jurisdictions, not only between states but within states. A 2004 Cornell University study showed that while 2.5 percent of murderers convicted nationwide were sentenced to the death penalty, in Nevada 6 percent were given the death penalty. Texas gave 2 percent of murderers a death sentence, less than the national average. Texas, however, executed 40 percent of those sentenced, which was about four times higher than the national average. California had executed only 1 percent of those sentenced.

Now answer this question: What percentage of murderers in California are given the death penalty and subsequently executed?

Output: 1

Article: On tracks that London Underground share with National Rail third-rail stock (the Bakerloo and District lines both have such sections), the centre rail is connected to the running rails, allowing both types of train to operate, at a compromise voltage of 660 V. Underground trains pass from one section to the other at speed; lineside electrical connections and resistances separate the two types of supply. These routes were originally solely electrified on the four-rail system by the LNWR before National Rail trains were rewired to their standard three-rail system to simplify rolling stock use.

Question: Why some sections of Bakerloo and District lines were rewired to three-rail system?
Ans: to simplify rolling stock use

Here is a question about this article: The 1960s and 1970s saw an acceleration in the decolonisation of Africa and the Caribbean. Over 20 countries gained independence from Britain as part of a planned transition to self-government. In 1965, however, the Rhodesian Prime Minister, Ian Smith, in opposition to moves toward majority rule, declared unilateral independence from Britain while still expressing "loyalty and devotion" to Elizabeth. Although the Queen dismissed him in a formal declaration, and the international community applied sanctions against Rhodesia, his regime survived for over a decade. As Britain's ties to its former empire weakened, the British government sought entry to the European Community, a goal it achieved in 1973.
What is the answer to this question: In spite of sanctions by the international community, how long did the Ian Smith's regime last?
****
So... over a decade

Question: Read this and answer the question

Whether there are measurable changes in the sea level relative to the islands of Tuvalu is a contentious issue. There were problems associated with the pre-1993 sea level records from Funafuti which resulted in improvements in the recording technology to provide more reliable data for analysis. The degree of uncertainty as to estimates of sea level change relative to the islands of Tuvalu was reflected in the conclusions made in 2002 from the available data. The 2011 report of the Pacific Climate Change Science Program published by the Australian Government, concludes: "The sea-level rise near Tuvalu measured by satellite altimeters since 1993 is about 5 mm (0.2 in) per year."

What is assumed about the sea level reports and records of Tuvalu?
Answer:
degree of uncertainty
