Input: Article: Fox announced on May 11, 2015 that the fifteenth season would be the final season of American Idol; as such, the season is expected to have an additional focus on the program's alumni. Ryan Seacrest returns as host, with Harry Connick Jr., Keith Urban, and Jennifer Lopez all returning for their respective third, fourth, and fifth seasons as judges.

Now answer this question: What year did Fox announce the cancellation of American Idol?

Output: 2015

Input: Article: Reflections generally affect polarization. For radio waves, one important reflector is the ionosphere which can change the wave's polarization. Thus for signals received following reflection by the ionosphere (a skywave), a consistent polarization cannot be expected. For line-of-sight communications or ground wave propagation, horizontally or vertically polarized transmissions generally remain in about the same polarization state at the receiving location. Matching the receiving antenna's polarization to that of the transmitter can make a very substantial difference in received signal strength.

Now answer this question: What will you be matching with the receiving antenna's polarization?

Output: transmitter

Input: Article: From the German point of view, March 1941 saw an improvement. The Luftwaffe flew 4,000 sorties that month, including 12 major and three heavy attacks. The electronic war intensified but the Luftwaffe flew major inland missions only on moonlit nights. Ports were easier to find and made better targets. To confuse the British, radio silence was observed until the bombs fell. X- and Y-Gerat beams were placed over false targets and switched only at the last minute. Rapid frequency changes were introduced for X-Gerat, whose wider band of frequencies and greater tactical flexibility ensured it remained effective at a time when British selective jamming was degrading the effectiveness of Y-Gerat.

Now answer this question: When did the Luftwaffe fly inland missions?

Output:
only on moonlit nights
