Problem: Given the question: Given the following passage  "Many other databases have application software that accesses the database on behalf of end-users, without exposing the DBMS interface directly. Application programmers may use a wire protocol directly, or more likely through an application programming interface. Database designers and database administrators interact with the DBMS through dedicated interfaces to build and maintain the applications' databases, and thus need some more knowledge and understanding about how DBMSs operate and the DBMSs' external interfaces and tuning parameters.",  answer the following question. Note that the answer is present within the text.  Question: When might a wire protocol be used?
++++++++++++++++++++++++++++++++
The answer is:
application software that accesses the database on behalf of end-users


Problem: Given the question: Given the following passage  "As an electro-magnetic wave travels through the different parts of the antenna system (radio, feed line, antenna, free space) it may encounter differences in impedance (E/H, V/I, etc.). At each interface, depending on the impedance match, some fraction of the wave's energy will reflect back to the source, forming a standing wave in the feed line. The ratio of maximum power to minimum power in the wave can be measured and is called the standing wave ratio (SWR). A SWR of 1:1 is ideal. A SWR of 1.5:1 is considered to be marginally acceptable in low power applications where power loss is more critical, although an SWR as high as 6:1 may still be usable with the right equipment. Minimizing impedance differences at each interface (impedance matching) will reduce SWR and maximize power transfer through each part of the antenna system.",  answer the following question. Note that the answer is present within the text.  Question: What do electromagnetic waves encounter?
++++++++++++++++++++++++++++++++
The answer is:
E/H, V/I, etc


Problem: Given the question: Given the following passage  "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.",  answer the following question. Note that the answer is present within the text.  Question: What do many people do to their water before storing it?
++++++++++++++++++++++++++++++++
The answer is:
SODIS
