Input: MP3
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.

What is measuring and storing loudness of an MP3 file also known as?
Output: audio normalization

Input: Article: Education remained mostly focused on the training of future clergy. The basic learning of the letters and numbers remained the province of the family or a village priest, but the secondary subjects of the triviumgrammar, rhetoric, logicwere studied in cathedral schools or in schools provided by cities. Commercial secondary schools spread, and some Italian towns had more than one such enterprise. Universities also spread throughout Europe in the 14th and 15th centuries. Lay literacy rates rose, but were still low; one estimate gave a literacy rate of ten per cent of males and one per cent of females in 1500.

Now answer this question: What was the main purpose of education in this period?

Output: training of future clergy

Article: The Perpetual Virginity of Mary asserts Mary's real and perpetual virginity even in the act of giving birth to the Son of God made Man. The term Ever-Virgin (Greek ) is applied in this case, stating that Mary remained a virgin for the remainder of her life, making Jesus her biological and only son, whose conception and birth are held to be miraculous. While the Orthodox Churches hold the position articulated in the Protoevangelium of James that Jesus' brothers and sisters are older children of Joseph the Betrothed, step-siblings from an earlier marriage that left him widowed, Roman Catholic teaching follows the Latin father Jerome in considering them Jesus' cousins.

Question: Which doctrine describes the belief that Mary remained a virgin, even though she gave birth to Jesus?
Ans: The Perpetual Virginity of Mary

Here is a question about this article: Small, cheap discoidal ceramic capacitors have existed since the 1930s, and remain in widespread use. Since the 1980s, surface mount packages for capacitors have been widely used. These packages are extremely small and lack connecting leads, allowing them to be soldered directly onto the surface of printed circuit boards. Surface mount components avoid undesirable high-frequency effects due to the leads and simplify automated assembly, although manual handling is made difficult due to their small size.
What is the answer to this question: What do surface mount packages lack that allows their use on the surface of printed circuit boards?
****
So... connecting leads

The Lobund Institute grew out of pioneering research in germ-free-life which began in 1928. This area of research originated in a question posed by Pasteur as to whether animal life was possible without bacteria. Though others had taken up this idea, their research was short lived and inconclusive. Lobund was the first research organization to answer definitively, that such life is possible and that it can be prolonged through generations. But the objective was not merely to answer Pasteur's question but also to produce the germ free animal as a new tool for biological and medical research. This objective was reached and for years Lobund was a unique center for the study and production of germ free animals and for their use in biological and medical investigations. Today the work has spread to other universities. In the beginning it was under the Department of Biology and a program leading to the master's degree accompanied the research program. In the 1940s Lobund achieved independent status as a purely research organization and in 1950 was raised to the status of an Institute. In 1958 it was brought back into the Department of Biology as integral part of that department, but with its own program leading to the degree of PhD in Gnotobiotics.
Work on a germ-free-life ended up in the creation of which Notre Dame institute?
****
The answer: The Lobund Institute

The problem: Answer a question about this article:
Nathan Knorr was appointed as third president of the Watch Tower Bible and Tract Society in 1942. Knorr commissioned a new translation of the Bible, the New World Translation of the Holy Scriptures, the full version of which was released in 1961. He organized large international assemblies, instituted new training programs for members, and expanded missionary activity and branch offices throughout the world. Knorr's presidency was also marked by an increasing use of explicit instructions guiding Witnesses in their lifestyle and conduct, and a greater use of congregational judicial procedures to enforce a strict moral code.
Who was appointed as the third president of the Watch Tower Bible and Tract Society in 1942?
****
The answer:
Nathan Knorr
