In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Ex Input:
What happens if the capacitor can handle maximum amount of reversal?, Context: For maximum life, capacitors usually need to be able to handle the maximum amount of reversal that a system will experience. An AC circuit will experience 100% voltage reversal, while under-damped DC circuits will experience less than 100%. Reversal creates excess electric fields in the dielectric, causes excess heating of both the dielectric and the conductors, and can dramatically shorten the life expectancy of the capacitor. Reversal ratings will often affect the design considerations for the capacitor, from the choice of dielectric materials and voltage ratings to the types of internal connections used.

Ex Output:
100% voltage reversal

Ex Input:
Who practices SODIS?, Context: Solar water disinfection (SODIS) involves exposing water-filled plastic polyethylene terephthalate (PET) bottles to sunlight for several hours. Exposure times vary depending on weather and climate from a minimum of six hours to two days during fully overcast conditions. It is recommended by the World Health Organization as a viable method for household water treatment and safe storage. Over two million people in developing countries use this method for their daily drinking water.

Ex Output:
Over two million people

Ex Input:
What VOC and WIC in the business of?, Context: The States General of the United Provinces were in control of the Dutch East India Company (VOC) and the Dutch West India Company (WIC), but some shipping expeditions were initiated by some of the provinces, mostly Holland and/or Zeeland.

Ex Output:
shipping
