Input: Printed circuit board
The cloth or fiber material used, resin material, and the cloth to resin ratio determine the laminate's type designation (FR-4, CEM-1, G-10, etc.) and therefore the characteristics of the laminate produced. Important characteristics are the level to which the laminate is fire retardant, the dielectric constant (er), the loss factor (t), the tensile strength, the shear strength, the glass transition temperature (Tg), and the Z-axis expansion coefficient (how much the thickness changes with temperature).

What element of a laminate is designated by the cloth to resin ratio, among other things?
Output: type designation

Input: Article: Clinical immunology is the study of diseases caused by disorders of the immune system (failure, aberrant action, and malignant growth of the cellular elements of the system). It also involves diseases of other systems, where immune reactions play a part in the pathology and clinical features.

Now answer this question: What else does clinical immunology concern itself with?

Output: diseases of other systems

Article: Solar distillation can be used to make saline or brackish water potable. The first recorded instance of this was by 16th-century Arab alchemists. A large-scale solar distillation project was first constructed in 1872 in the Chilean mining town of Las Salinas. The plant, which had solar collection area of 4,700 m2 (51,000 sq ft), could produce up to 22,700 L (5,000 imp gal; 6,000 US gal) per day and operate for 40 years. Individual still designs include single-slope, double-slope (or greenhouse type), vertical, conical, inverted absorber, multi-wick, and multiple effect. These stills can operate in passive, active, or hybrid modes. Double-slope stills are the most economical for decentralized domestic purposes, while active multiple effect units are more suitable for large-scale applications.

Question: In what year was a large scale solar distillation project constructed in Las Salinas?
Ans: 1872

Here is a question about this article: In September 1216 John began a fresh, vigorous attack. He marched from the Cotswolds, feigned an offensive to relieve the besieged Windsor Castle, and attacked eastwards around London to Cambridge to separate the rebel-held areas of Lincolnshire and East Anglia. From there he travelled north to relieve the rebel siege at Lincoln and back east to King's Lynn, probably to order further supplies from the continent.[nb 17] In King's Lynn, John contracted dysentery, which would ultimately prove fatal. Meanwhile, Alexander II invaded northern England again, taking Carlisle in August and then marching south to give homage to Prince Louis for his English possessions; John narrowly missed intercepting Alexander along the way. Tensions between Louis and the English barons began to increase, prompting a wave of desertions, including William Marshal's son William and William Longespee, who both returned to John's faction.
What is the answer to this question: Where did John contract dysentery?
****
So... King's Lynn

After the Incheon landing, the 1st Cavalry Division began its northward advance from the Pusan Perimeter. "Task Force Lynch" (after Lieutenant Colonel James H. Lynch), 3rd Battalion, 7th Cavalry Regiment, and two 70th Tank Battalion units (Charlie Company and the IntelligenceReconnaissance Platoon) effected the "Pusan Perimeter Breakout" through 106.4 miles (171.2 km) of enemy territory to join the 7th Infantry Division at Osan. The X Corps rapidly defeated the KPA defenders around Seoul, thus threatening to trap the main KPA force in Southern Korea.
Who was defeated near Seoul, Korea?
****
The answer: the KPA

Between 1975 and 2009, Olympic Airways (known after 2003 as Olympic Airlines) was the country's state-owned flag carrier, but financial problems led to its privatization and relaunch as Olympic Air in 2009. Both Aegean Airlines and Olympic Air have won awards for their services; in 2009 and 2011, Aegean Airlines was awarded the "Best regional airline in Europe" award by Skytrax, and also has two gold and one silver awards by the ERA, while Olympic Air holds one silver ERA award for "Airline of the Year" as well as a "Conde Nast Traveller 2011 Readers Choice Awards: Top Domestic Airline" award.
What was Olympic Airlines relaunched as in 2009?
****
The answer:
Olympic Air
