Input: Article: The architectural history of Estonia mainly reflects its contemporary development in northern Europe. Worth mentioning is especially the architectural ensemble that makes out the medieval old town of Tallinn, which is on the UNESCO World Heritage List. In addition, the country has several unique, more or less preserved hill forts dating from pre-Christian times, a large number of still intact medieval castles and churches, while the countryside is still shaped by the presence of a vast number of manor houses from earlier centuries.

Now answer this question: What institutional structures still exist from medieval times?

Output: castles and churches

Input: Article: Instead, it is often desired to have an antenna whose impedance does not vary so greatly over a certain bandwidth. It turns out that the amount of reactance seen at the terminals of a resonant antenna when the frequency is shifted, say, by 5%, depends very much on the diameter of the conductor used. A long thin wire used as a half-wave dipole (or quarter wave monopole) will have a reactance significantly greater than the resistive impedance it has at resonance, leading to a poor match and generally unacceptable performance. Making the element using a tube of a diameter perhaps 1/50 of its length, however, results in a reactance at this altered frequency which is not so great, and a much less serious mismatch which will only modestly damage the antenna's net performance. Thus rather thick tubes are typically used for the solid elements of such antennas, including Yagi-Uda arrays.

Now answer this question: What would be used to create a half wave or quarter wave dipole?

Output: A long thin wire

Input: Article: Chopin's life was covered in a BBC TV documentary Chopin The Women Behind The Music (2010), and in a 2010 documentary realised by Angelo Bozzolini and Roberto Prosseda for Italian television.

Now answer this question: What was the title of the documentary the BBC released?

Output:
The Women Behind The Music
