Input: Printed circuit board
Cordwood construction can save significant space and was often used with wire-ended components in applications where space was at a premium (such as missile guidance and telemetry systems) and in high-speed computers, where short traces were important. In cordwood construction, axial-leaded components were mounted between two parallel planes. The components were either soldered together with jumper wire, or they were connected to other components by thin nickel ribbon welded at right angles onto the component leads. To avoid shorting together different interconnection layers, thin insulating cards were placed between them. Perforations or holes in the cards allowed component leads to project through to the next interconnection layer. One disadvantage of this system was that special nickel-leaded components had to be used to allow the interconnecting welds to be made. Differential thermal expansion of the component could put pressure on the leads of the components and the PCB traces and cause physical damage (as was seen in several modules on the Apollo program). Additionally, components located in the interior are difficult to replace. Some versions of cordwood construction used soldered single-sided PCBs as the interconnection method (as pictured), allowing the use of normal-leaded components.

What force caused the physical damage to components that affected the Apollo program?
Output: Differential thermal expansion

Input: Federalism
The Philippines is a unitary state with some powers devolved to Local Government Units (LGUs) under the terms of the Local Government Code. There is also one autonomous region, the Autonomous Region of Muslim Mindanao. Over the years various modifications have been proposed to the Constitution of the Philippines, including possible transition to a federal system as part of a shift to a parliamentary system. In 2004, Philippine President Gloria Macapagal Arroyo established the Consultative Commission which suggested such a Charter Change but no action was taken by the Philippine Congress to amend the 1987 Constitution.

What type of modifications been added to the Philippines Constitution? 
Output: possible transition to a federal system as part of a shift to a parliamentary system.

Input: Dwight D. Eisenhower
The last three years of Eisenhower's second term in office were ones of relatively good health. Eventually after leaving the White House, he suffered several additional and ultimately crippling heart attacks. A severe heart attack in August 1965 largely ended his participation in public affairs. In August 1966 he began to show symptoms of cholecystitis, for which he underwent surgery on December 12, 1966, when his gallbladder was removed, containing 16 gallstones. After Eisenhower's death in 1969 (see below), an autopsy unexpectedly revealed an adrenal pheochromocytoma, a benign adrenaline-secreting tumor that may have made the President more vulnerable to heart disease. Eisenhower suffered seven heart attacks in total from 1955 until his death.

What August 1965 event caused Eisenhower to drop out of public life?
Output: heart attack

Input: Human Development Index
A HDI of 0.8 or more is considered to represent "high development". This includes all developed countries, such as those in North America, Western Europe, Oceania, and Eastern Asia, as well as some developing countries in Eastern Europe, Central and South America, Southeast Asia, the Caribbean, and the oil-rich Arabian Peninsula. Seven countries were promoted to this category this year, leaving the "medium development" group: Albania, Belarus, Brazil, Libya, Macedonia, Russia and Saudi Arabia.

What number indicates the minimum score for a country to be considered a "high development" country?
Output:
0.8
