input question: Question: "What happened second, the first traffic light was erected or the first modern electric traffic lights were put up?" Context: "Green can communicate safety to proceed, as in traffic lights. Green and red were standardized as the colors of international railroad signals in the 19th century. The first traffic light, using green and red gas lamps, was erected in 1868 in front of the Houses of Parliament in London. It exploded the following year, injuring the policeman who operated it. In 1912, the first modern electric traffic lights were put up in Salt Lake City, Utah. Red was chosen largely because of its high visibility, and its association with danger, while green was chosen largely because it could not be mistaken for red. Today green lights universally signal that a system is turned on and working as it should. In many video games, green signifies both health and completed objectives, opposite red." Answer:???

[Q]: Question: "Which of the following words in not in Dutch: voorraaddoos, zee-eend, or sea duck?" Context: "Dutch is written using the Latin script. Dutch uses one additional character beyond the standard alphabet, the digraph IJ. It has a relatively high proportion of doubled letters, both vowels and consonants, due to the formation of compound words and also to the spelling devices for distinguishing the many vowel sounds in the Dutch language. An example of five consecutive doubled letters is the word voorraaddoos (food storage container). The diaeresis (Dutch: trema) is used to mark vowels that are pronounced separately when involving a pre- or suffix. Whereas a hyphen is used when this problem occurs in compound words. For example; "beinvloed" (influenced), but zee-eend (sea duck). Generally, other diacritical marks only occur in loanwords, though the acute accent can also be used for emphasis or to differentiate between two forms. Its most common use is to differentiate between the indefinite article 'een' (a, an) and the numeral 'een' (one)." Answer:
****
[A]: sea duck

Problem: Given the question: Question: "What raises different public policy issues?" Context: "Free Software Foundation founder Richard Stallman argues that, although the term intellectual property is in wide use, it should be rejected altogether, because it "systematically distorts and confuses these issues, and its use was and is promoted by those who gain from this confusion". He claims that the term "operates as a catch-all to lump together disparate laws [which] originated separately, evolved differently, cover different activities, have different rules, and raise different public policy issues" and that it creates a "bias" by confusing these monopolies with ownership of limited physical things, likening them to "property rights". Stallman advocates referring to copyrights, patents and trademarks in the singular and warns against abstracting disparate laws into a collective term." Answer:
++++++++++++++++++++++++++++++++
The answer is:
intellectual property
