Teacher:In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.
Teacher: Now, understand the problem? Solve this instance: Question: How many members were on the Puerto Rican boyband who first achieved crossover success with non-Latino listeners? Passage 1:In planning for the actual attack, Manteuffel had divided his 5th Panzer Army into three corps composed of infantry, tanks, and supporting artillery. The main effort, or schwerpunkt, would consist of XLVII Panzer Corps and LVIII Panzer Corps advancing west across the River Our at Ouren from the south or left flank of the German army front. They would then occupy the transportation center of Bastogne, before crossing the Meuse River at Namur. The third group, LXVI Corps, would advance west on either side of the Schnee Eifel. This northernmost, or right wing, element would flank and begin an envelopment of the American forces occupying fortifications on the Schnee Eifel and then converge on the town of Winterspelt. From there, LXVI Corps would cross the Our river and occupy St. Vith on the first day of the attack. LXVI Corps was the weakest of the three corps, with no attached tank division or motor transport, but did include an attached assault gun battalion. The Panzer Lehr Division (Armor Demonstration Division) and the Führer Begleit Brigade (Führer Escort Brigade) were to be held in reserve, with the Führer Begleit only usable with Model's express permission. Manteuffel's preference for the "little slam", or limited solution, was reflected in the absence of planning beyond reaching the Meuse River.
 Passage 2:Latin pop became the most popular form of Latin music in the United States during the 1980s and 1990s, with acts such as Puerto Rican boyband Menudo, even achieving massive crossover success among non-Latino listeners during the late 1990s. While not restricted to America by any means, Latin pop was profoundly affected by production techniques and other styles of music — both Latin and otherwise — that originated primarily in the United States. Tejano music, centered in Texas and the U.S./Mexico border region, had begun to introduce synthesizers, slicker production, and a more urban sensibility to formerly root styles like norteño and conjunto. Moreover, New York and Miami were home to thriving Latin club scenes, which during the 1980s led to the rise of Latin freestyle, a club-oriented dance music that was rooted in Latin rhythms but relied on synthesizers and drum machines for most of its arrangements. Both of these sounds influenced the rise of Latin pop, which retained Latin rhythms in its uptempo numbers but relied more on mainstream pop for its melodic sense.
 Passage 3:As designed in 1931, the He 46 was a two-seat sesquiplane of mixed construction. The upper wing was swept back 10°. This is a common trick when a change in an aircraft's design moves the center of gravity to the rear; rather than moving the whole wing back to counter for the shift, it is easier to simply angle the wings back slightly, which requires very little change to the basic design, or even the overall structure of the wing. (The similarly angled wings on the Fairey Swordfish are due to just such a mid-program change to the weight distribution of the aircraft.) The tailplane was mounted high and braced by struts. The undercarriage was fixed, and the tail was fitted with a skid rather than a wheel. The He 46 prototype first flew in late 1931; its flight characteristics were good, but design improvements were incorporated. The small lower wing was removed, while the mainplane was increased in area by 22% and braced to the fuselage, transforming the He 46 into a parasol-wing monoplane. A more powerful engine was added to the second prototype, and a single 7.92 mm (.312 in) MG 15 machine gun for the rear seat was added to the third prototype.
