Input: Airport
An airport is an aerodrome with facilities for flights to take off and land. Airports often have facilities to store and maintain aircraft, and a control tower. An airport consists of a landing area, which comprises an aerially accessible open space including at least one operationally active surface such as a runway for a plane to take off or a helipad, and often includes adjacent utility buildings such as control towers, hangars  and terminals. Larger airports may have fixed base operator services, airport aprons, air traffic control centres, passenger facilities such as restaurants and lounges, and emergency services.

What is an aerodome with facilities for flights to take off and land?

Input: MP3
An additional extension to MPEG-2 is named MPEG-2.5 audio, as MPEG-3 already had a different meaning. This extension was developed at Fraunhofer IIS, the registered MP3 patent holders. Like MPEG-2, MPEG-2.5 adds new sampling rates exactly half of that previously possible with MPEG-2. It thus widens the scope of MP3 to include human speech and other applications requiring only 25% of the frequency reproduction possible with MPEG-1. While not an ISO recognized standard, MPEG-2.5 is widely supported by both inexpensive and brand name digital audio players as well as computer software based MP3 encoders and decoders. A sample rate comparison between MPEG-1, 2 and 2.5 is given further down. MPEG-2.5 was not developed by MPEG and was never approved as an international standard. MPEG-2.5 is thus an unofficial or proprietary extension to the MP3 format.

Where was this extension developed?
Output: Fraunhofer IIS

Input: Adult contemporary music
With the mixture of radio friendly AC tunes with some rock and pop fare also landing on the pop charts, mainstream songs won over many critics in the need to define AC, and appeared to change the tolerance and acceptance of AC music into mainstream day to day radio play. Part of the reason why more and more hot AC stations are forced to change is that less and less new music fits their bill; most new rock is too alternative for mainstream radio and most new pop is now influenced heavily by dance-pop and electronic dance music.

Who have hot AC format radio stations had to change the music they play?
Output: less and less new music fits their bill

Input: Neolithic
Around 10,200 BC the first fully developed Neolithic cultures belonging to the phase Pre-Pottery Neolithic A (PPNA) appeared in the fertile crescent. Around 10,700 to 9,400 BC a settlement was established in Tell Qaramel, 10 miles north of Aleppo. The settlement included 2 temples dating back to 9,650. Around 9000 BC during the PPNA, one of the world's first towns, Jericho, appeared in the Levant. It was surrounded by a stone and marble wall and contained a population of 2000–3000 people and a massive stone tower. Around 6,400 BC the Halaf culture appeared in Lebanon, Israel and Palestine, Syria, Anatolia, and Northern Mesopotamia and subsisted on dryland agriculture.

What materials were used to build the wall around Jericho?
Output:
stone and marble
