Input: Read this: The problem of the direction of time arises directly from two contradictory facts. Firstly, the fundamental physical laws are time-reversal invariant; if a cinematographic film were taken of any process describable by means of the aforementioned laws and then played backwards, it would still portray a physically possible process. Secondly, our experience of time, at the macroscopic level, is not time-reversal invariant. Glasses can fall and break, but shards of glass cannot reassemble and fly up onto tables. We have memories of the past, and none of the future. We feel we can't change the past but can influence the future.
Question: What laws are time-reversal variant?

Output: unanswerable

Input: Read this: Another extreme case of impedance matching occurs when using a small loop antenna (usually, but not always, for receiving) at a relatively low frequency where it appears almost as a pure inductor. Resonating such an inductor with a capacitor at the frequency of operation not only cancels the reactance but greatly magnifies the very small radiation resistance of such a loop.[citation needed] This is implemented in most AM broadcast receivers, with a small ferrite loop antenna resonated by a capacitor which is varied along with the receiver tuning in order to maintain resonance over the AM broadcast band
Question: When using a small loop antenna at a low frequency, what may occur?

Output: impedance matching

Input: Read this: Following the Ottoman ultimatum in September 1853, forces under the Ottoman general Omar Pasha crossed the Danube at Vidin and captured Calafat in October 1853. Simultaneously, in the east, the Ottomans crossed the Danube at Silistra and attacked the Russians at Oltenita. The resulting Battle of Oltenita was the first engagement following the declaration of war. The Russians counterattacked, but were beaten back. On 31 December 1853, the Ottoman forces at Calafat moved against the Russian force at Chetatea or Cetate, a small village nine miles north of Calafat, and engaged them on 6 January 1854. The battle began when the Russians made a move to recapture Calafat. Most of the heavy fighting, however, took place in and around Chetatea until the Russians were driven out of the village. Despite the setback at Chetatea, on 28 January 1854, Russian forces laid siege to Calafat. The siege would continue until May 1854 when the Russians lifted the siege. The Ottomans would also later beat the Russians in battle at Caracal.:13043
Question: What general crossed across the Danube at Vidin?

Output: Omar Pasha

Input: Read this: The University of Notre Dame has made being a sustainability leader an integral part of its mission, creating the Office of Sustainability in 2008 to achieve a number of goals in the areas of power generation, design and construction, waste reduction, procurement, food services, transportation, and water.As of 2012[update] four building construction projects were pursuing LEED-Certified status and three were pursuing LEED Silver. Notre Dame's dining services sources 40% of its food locally and offers sustainably caught seafood as well as many organic, fair-trade, and vegan options. On the Sustainable Endowments Institute's College Sustainability Report Card 2010, University of Notre Dame received a "B" grade. The university also houses the Kroc Institute for International Peace Studies. Father Gustavo Gutierrez, the founder of Liberation Theology is a current faculty member.
Question: Gustavo Gutierrez is faculty of which institute?

Output:
Kroc Institute for International Peace Studies
