Input: Read this: Heat is energy in transit that flows due to temperature difference. Unlike heat transmitted by thermal conduction or thermal convection, thermal radiation can propagate through a vacuum. Thermal radiation is characterized by a particular spectrum of many wavelengths that is associated with emission from an object, due to the vibration of its molecules at a given temperature. Thermal radiation can be emitted from objects at any wavelength, and at very high temperatures such radiations are associated with spectra far above the infrared, extending into visible, ultraviolet, and even X-ray regions (i.e., the solar corona). Thus, the popular association of infrared radiation with thermal radiation is only a coincidence based on typical (comparatively low) temperatures often found near the surface of planet Earth.
Question: What is the association of heat with thermal radiation?

Output: unanswerable


Input: Read this: After 539 Ravenna was reconquered by the Romans in the form of the Eastern Roman Empire (Byzantine Empire) and became the seat of the Exarchate of Ravenna. The greatest development of Christian mosaics unfolded in the second half of the 6th century. Outstanding examples of Byzantine mosaic art are the later phase mosaics in the Basilica of San Vitale and Basilica of Sant'Apollinare Nuovo. The mosaic depicting Emperor Saint Justinian I and Empress Theodora in the Basilica of San Vitale were executed shortly after the Byzantine conquest. The mosaics of the Basilica of Sant'Apollinare in Classe were made around 549. The anti-Arian theme is obvious in the apse mosaic of San Michele in Affricisco, executed in 545–547 (largely destroyed; the remains in Berlin).
Question: When were the mosaics at the Basilica of Sant'Apollinare created?

Output: 549


Input: Read this: On May 15, 2013, Resident Commissioner Pierluisi introduced H.R. 2000 to Congress to "set forth the process for Puerto Rico to be admitted as a state of the Union," asking for Congress to vote on ratifying Puerto Rico as the 51st state. On February 12, 2014, Senator Martin Heinrich introduced a bill in the US Senate. The bill would require a binding referendum to be held in Puerto Rico asking whether the territory wants to be admitted as a state. In the event of a yes vote, the president would be asked to submit legislation to Congress to admit Puerto Rico as a state.
Question: When was H.R. 2014 introduced?

Output: unanswerable


Input: Read this: In the 1874 general election, Disraeli was returned to power. He passed the Public Worship Regulation Act 1874, which removed Catholic rituals from the Anglican liturgy and which Victoria strongly supported. She preferred short, simple services, and personally considered herself more aligned with the presbyterian Church of Scotland than the episcopal Church of England. He also pushed the Royal Titles Act 1876 through Parliament, so that Victoria took the title "Empress of India" from 1 May 1876. The new title was proclaimed at the Delhi Durbar of 1 January 1877.
Question: In a general election of what year was Disraeli returned to power?

Output:
1874
