Input: Chinese characters
The use of traditional Chinese characters versus simplified Chinese characters varies greatly, and can depend on both the local customs and the medium. Before the official reform, character simplifications were not officially sanctioned and generally adopted vulgar variants and idiosyncratic substitutions. Orthodox variants were mandatory in printed works, while the (unofficial) simplified characters would be used in everyday writing or quick notes. Since the 1950s, and especially with the publication of the 1964 list, the People's Republic of China has officially adopted simplified Chinese characters for use in mainland China, while Hong Kong, Macau, and the Republic of China (Taiwan) were not affected by the reform. There is no absolute rule for using either system, and often it is determined by what the target audience understands, as well as the upbringing of the writer.

What were adopted for use in mainland China?
Output: Chinese characters

Input: Printed circuit board
The hole walls for boards with two or more layers can be made conductive and then electroplated with copper to form plated-through holes. These holes electrically connect the conducting layers of the PCB. For multi-layer boards, those with three layers or more, drilling typically produces a smear of the high temperature decomposition products of bonding agent in the laminate system. Before the holes can be plated through, this smear must be removed by a chemical de-smear process, or by plasma-etch. The de-smear process ensures that a good connection is made to the copper layers when the hole is plated through. On high reliability boards a process called etch-back is performed chemically with a potassium permanganate based etchant or plasma. The etch-back removes resin and the glass fibers so that the copper layers extend into the hole and as the hole is plated become integral with the deposited copper.

What's the minimum number of layers a PCB can have to be considered "multi-layer"?
Output: three

Input: Anti-aircraft warfare
The basic air defence unit is typically a battery with 2 to 12 guns or missile launchers and fire control elements. These batteries, particularly with guns, usually deploy in a small area, although batteries may be split; this is usual for some missile systems. SHORAD missile batteries often deploy across an area with individual launchers several kilometres apart. When MANPADS is operated by specialists, batteries may have several dozen teams deploying separately in small sections; self-propelled air defence guns may deploy in pairs.

Several dozen teams can deploy individually in small sections when what is handled by a specialist?
Output: MANPADS

Input: Saint Helena
Most residents belong to the Anglican Communion and are members of the Diocese of St Helena, which has its own bishop and includes Ascension Island. The 150th anniversary of the diocese was celebrated in June 2009.

What communion do most residents of the island belong to?
Output:
Anglican
