On September 11, 2001, 53 Army civilians (47 employees and six contractors) and 22 soldiers were among the 125 victims killed in the Pentagon in a terrorist attack when American Airlines Flight 77 commandeered by five Al-Qaeda hijackers slammed into the western side of the building, as part of the September 11 attacks. Lieutenant General Timothy Maude was the highest-ranking military official killed at the Pentagon, and the most senior U.S. Army officer killed by foreign action since the death of Lieutenant General Simon B. Buckner, Jr. on June 18, 1945, in the Battle of Okinawa during World War II.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who was the lowest ranking official killed in the attack?
Ah, so.. unanswerable

As the playing of gramophone records causes gradual degradation of the recording, they are best preserved by transferring them onto other media and playing the records as rarely as possible. They need to be stored on edge, and do best under environmental conditions that most humans would find comfortable. The medium needs to be kept clean, but alcohol should only be used on PVC or optical media, not on 78s.[citation needed] The equipment for playback of certain formats (e.g., 16 and 78 rpm) is manufactured only in small quantities, leading to increased difficulty in finding equipment to play the recordings.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is a drawback of gramophone use?
Ah, so.. gradual degradation

In the 1520s during the Protestant Reformation, the city, under the political guidance of Jacob Sturm von Sturmeck and the spiritual guidance of Martin Bucer embraced the religious teachings of Martin Luther. Their adherents established a Gymnasium, headed by Johannes Sturm, made into a University in the following century. The city first followed the Tetrapolitan Confession, and then the Augsburg Confession. Protestant iconoclasm caused much destruction to churches and cloisters, notwithstanding that Luther himself opposed such a practice. Strasbourg was a centre of humanist scholarship and early book-printing in the Holy Roman Empire, and its intellectual and political influence contributed much to the establishment of Protestantism as an accepted denomination in the southwest of Germany. (John Calvin spent several years as a political refugee in the city). The Strasbourg Councillor Sturm and guildmaster Matthias represented the city at the Imperial Diet of Speyer (1529), where their protest led to the schism of the Catholic Church and the evolution of Protestantism. Together with four other free cities, Strasbourg presented the confessio tetrapolitana as its Protestant book of faith at the Imperial Diet of Augsburg in 1530, where the slightly different Augsburg Confession was also handed over to Charles V, Holy Roman Emperor.

Ah, so..
