Input: Article: ReplayGain is a standard for measuring and storing the loudness of an MP3 file (audio normalization) in its metadata tag, enabling a ReplayGain-compliant player to automatically adjust the overall playback volume for each file. MP3Gain may be used to reversibly modify files based on ReplayGain measurements so that adjusted playback can be achieved on players without ReplayGain capability.

Now answer this question: MP3Gain is important because it allows players without what capability to have adjusted playback?

Output: ReplayGain capability


Article: For example, character 10 represents the "line feed" function (which causes a printer to advance its paper), and character 8 represents "backspace". RFC 2822 refers to control characters that do not include carriage return, line feed or white space as non-whitespace control characters. Except for the control characters that prescribe elementary line-oriented formatting, ASCII does not define any mechanism for describing the structure or appearance of text within a document. Other schemes, such as markup languages, address page and document layout and formatting.

Question: What does the "line feed" function do?
Ans: causes a printer to advance its paper


Here is a question about this article: In 1882, Albert Zahm (John Zahm's brother) built an early wind tunnel used to compare lift to drag of aeronautical models. Around 1899, Professor Jerome Green became the first American to send a wireless message. In 1931, Father Julius Nieuwland performed early work on basic reactions that was used to create neoprene. Study of nuclear physics at the university began with the building of a nuclear accelerator in 1936, and continues now partly through a partnership in the Joint Institute for Nuclear Astrophysics.
What is the answer to this question: Which professor sent the first wireless message in the USA?
****
So... Professor Jerome Green

The result was a sequence of innovative but unpopular financial measures.[nb 10] John levied scutage payments eleven times in his seventeen years as king, as compared to eleven times in total during the reign of the preceding three monarchs. In many cases these were levied in the absence of any actual military campaign, which ran counter to the original idea that scutage was an alternative to actual military service. John maximised his right to demand relief payments when estates and castles were inherited, sometimes charging enormous sums, beyond barons' abilities to pay. Building on the successful sale of sheriff appointments in 1194, John initiated a new round of appointments, with the new incumbents making back their investment through increased fines and penalties, particularly in the forests. Another innovation of Richard's, increased charges levied on widows who wished to remain single, was expanded under John. John continued to sell charters for new towns, including the planned town of Liverpool, and charters were sold for markets across the kingdom and in Gascony.[nb 11] The king introduced new taxes and extended existing ones. The Jews, who held a vulnerable position in medieval England, protected only by the king, were subject to huge taxes; £44,000 was extracted from the community by the tallage of 1210; much of it was passed on to the Christian debtors of Jewish moneylenders.[nb 12] John created a new tax on income and movable goods in 1207 – effectively a version of a modern income tax – that produced £60,000; he created a new set of import and export duties payable directly to the crown. John found that these measures enabled him to raise further resources through the confiscation of the lands of barons who could not pay or refused to pay.
How many times did John levi scutage payments?
****
The answer: eleven


Problem: Please answer a question about the following article about Himachal Pradesh:
Railway Himachal is famous for its narrow gauge tracks railways, one is UNESCO World Heritage Kalka-Shimla Railway and another one is Pathankot–Jogindernagar. Total length of these two tracks is 259 kilometres (161 mi). Kalka-Shimla Railway track passes through many tunnels, while Pathankot–Jogindernagar gently meanders through a maze of hills and valleys. It also has standard gauge railway track which connect Amb (Una district) to Delhi. A survey is being conducted to extend this railway line to Kangra (via Nadaun). Other proposed railways in the state are Baddi-Bilaspur, Dharamsala-Palampur and Bilaspur-Manali-Leh.
What are the 2 narrow gauge railways in the Railway Himachal?
A: UNESCO World Heritage Kalka-Shimla Railway and another one is Pathankot–Jogindernagar


Question: Read this and answer the question

It was not unusual for electric recordings to be played back on acoustic phonographs. The Victor Orthophonic phonograph was a prime example where such playback was expected. In the Orthophonic, which benefited from telephone research, the mechanical pickup head was redesigned with lower resonance than the traditional mica type. Also, a folded horn with an exponential taper was constructed inside the cabinet to provide better impedance matching to the air. As a result, playback of an Orthophonic record sounded like it was coming from a radio.

What is one example of an acoustic phonograph on which one would listen to electric recordings?
Answer:
Victor Orthophonic phonograph
