Input: Article: The events of the Franco-Prussian War had great influence on military thinking over the next forty years. Lessons drawn from the war included the need for a general staff system, the scale and duration of future wars and the tactical use of artillery and cavalry. The bold use of artillery by the Prussians, to silence French guns at long range and then to directly support infantry attacks at close range, proved to be superior to the defensive doctrine employed by French gunners. The Prussian tactics were adopted by European armies by 1914, exemplified in the French 75, an artillery piece optimised to provide direct fire support to advancing infantry. Most European armies ignored the evidence of the Russo-Japanese War of 1904–05 which suggested that infantry armed with new smokeless-powder rifles could engage gun crews effectively. This forced gunners to fire at longer range using indirect fire, usually from a position of cover.

Now answer this question: The events of the Franco-Prussian War had great influence on what?

Output: military thinking

Input: Article: Contrary to popular belief, if placed properly and prepared-for, drums could be effectively used and heard on even the earliest jazz and military band recordings. The loudest instruments such as the drums and trumpets were positioned the farthest away from the collecting horn. Lillian Hardin Armstrong, a member of King Oliver's Creole Jazz Band, which recorded at Gennett Records in 1923, remembered that at first Oliver and his young second trumpet, Louis Armstrong, stood next to each other and Oliver's horn could not be heard. "They put Louis about fifteen feet over in the corner, looking all sad." For fading instrumental parts in and out while recording, some performers were placed on a moveable platform, which could draw the performer(s) nearer or further away as required.[citation needed]

Now answer this question: What was the item called that recorded the sounds?

Output: collecting horn

Input: Article: Discrete transistors are individually packaged transistors. Transistors come in many different semiconductor packages (see image). The two main categories are through-hole (or leaded), and surface-mount, also known as surface-mount device (SMD). The ball grid array (BGA) is the latest surface-mount package (currently only for large integrated circuits). It has solder "balls" on the underside in place of leads. Because they are smaller and have shorter interconnections, SMDs have better high-frequency characteristics but lower power rating.

Now answer this question: What is a ball grid array composed of?

Output:
solder "balls" on the underside in place of leads
