This task is about writing a correct answer for the reading comprehension task. Based on the information provided in a given passage, you should identify the shortest continuous text span from the passage that serves as an answer to the given question. Avoid answers that are incorrect or provides incomplete justification for the question.

Example Input: Passage: In 2011, it became apparent that the bail-out would be insufficient and a second bail-out amounting to €130 billion ($173 billion) was agreed in 2012, subject to strict conditions, including financial reforms and further austerity measures. As part of the deal, there was to be a 53% reduction in the Greek debt burden to private creditors and any profits made by Eurozone central banks on their holdings of Greek debt are to be repatriated back to Greece. Greece achieved a primary government budget surplus in 2013. In April 2014, Greece returned to the global bond market as it successfully sold €3 billion worth of five-year government bonds at a yield of 4.95%. Greece returned to growth after six years of economic decline in the second quarter of 2014, and was the Eurozone's fastest-growing economy in the third quarter. Question: In what year did Greece realize a budget surplus?
Example Output: 2013

Example Input: Passage: Advanced economies led global economic growth prior to the financial crisis with "emerging" and "developing" economies lagging behind. The crisis completely overturned this relationship. The International Monetary Fund found that "advanced" economies accounted for only 31% of global GDP while emerging and developing economies accounted for 69% of global GDP from 2007 to 2014. In the tables, the names of emergent economies are shown in boldface type, while the names of developed economies are in Roman (regular) type. Question: How much global GDP did "advanced" economies account for from 2007 to 2014?
Example Output: 31%

Example Input: Passage: The first PCBs used through-hole technology, mounting electronic components by leads inserted through holes on one side of the board and soldered onto copper traces on the other side. Boards may be single-sided, with an unplated component side, or more compact double-sided boards, with components soldered on both sides. Horizontal installation of through-hole parts with two axial leads (such as resistors, capacitors, and diodes) is done by bending the leads 90 degrees in the same direction, inserting the part in the board (often bending leads located on the back of the board in opposite directions to improve the part's mechanical strength), soldering the leads, and trimming off the ends. Leads may be soldered either manually or by a wave soldering machine. Question: For boards with two sides, to what angle are leads bent to in order to install them horizontally?
Example Output:
