Input: Consider Input: Passage: The first complete Tosca recording was made in 1918, using the acoustic process. The conductor, Carlo Sabajno, had been the Gramophone Company's house conductor since 1904; he had made early complete recordings of several operas, including Verdi's La traviata and Rigoletto, before tackling Tosca with a largely unknown cast, featuring the Italian soprano Lya Remondini in the title role. The next year, in 1919, Sabajno recorded Tosca again, this time with more well-known singers, including Valentina Bartolomasi and Attilio Salvaneschi as Tosca and Cavaradossi. Ten years later, in 1929, Sabajno returned to the opera for the third time, recording it, by the electrical process, with the orchestra and chorus of the Teatro alla Scala and with stars Carmen Melis and Apollo Granforte in the roles of Tosca and Scarpia. In 1938 HMV secured the services of the renowned tenor Beniamino Gigli, together with the soprano Maria Caniglia as Tosca and conductor Oliviero De Fabritiis, for a "practically complete" recording that extended over 14 double-sided shellac discs.

Output: How many years after the acoustic press were shellac discs invented?

Input: Consider Input: Passage: Route 104 begins at an intersection with Route 137 in the Bulls Head section of Stamford and heads north, passing by GE Capital, then crossing the Rippowam River, up through North Stamford and onto New York state line. About north of the river, Route 104 crosses under the Merritt Parkway (Route 15) at Exit 34 into the North Stamford section of the city. After another , Route 104 crosses over the Mianus River, through the Long Ridge section of the city, as it heads towards the New York state line. The road ends in the town of Pound Ridge, New York and continues as Westchester County Road 3. Route 104 is known as Long Ridge Road throughout its length and is classified as a principal arterial road, carrying traffic volumes of as much as 30,000 vehicles per day, particularly near the Merritt Parkway interchange. Route 104 is four lanes wide from Route 137 to Route 15, and two lanes wide north of Route 15.
Link Information: for about 9.3 mi from Downtown Stamford up to North Stamford and then to New York state line in the town of Pound Ridge, New York. Answer: Pound Ridge, New York

Output: Where does the route end that 104 intersects with in Stamford?

Input: Consider Input: Passage: The military history of the Aleutian Islands began almost immediately following the purchase of Alaska from the Russian Empire by the United States in 1867. Prior to the early 20th century, the Aleutian Islands were essentially ignored by the United States Armed Forces, although the islands played a small role in the Bering Sea Arbitration when a number of British and American vessels were stationed at Unalaska to enforce the arbitrators' decision. By the early 20th century, a number of war strategies examined the possibility of conflict breaking out between the Empire of Japan and the United States. While the Aleutian Islands were seen as a potential staging point for invasions by either side, this possibility was dismissed owing to the islands' dismal climate. In 1922, the Washington Naval Treaty was signed, after which the United States Navy began to take an interest in the islands. However, nothing of significance was to materialize until World War II.
Link Information: the Imperial Japanese Navy at the same time made its surprise attack on Pearl Harbor in Honolulu on December 7, 1941 Answer: December 7, 1941
Output: When did the empire that could potentially invade the islands first experience military conflict with the United States?
