Input: Article: The electrolysis of water is a simple method of producing hydrogen. A low voltage current is run through the water, and gaseous oxygen forms at the anode while gaseous hydrogen forms at the cathode. Typically the cathode is made from platinum or another inert metal when producing hydrogen for storage. If, however, the gas is to be burnt on site, oxygen is desirable to assist the combustion, and so both electrodes would be made from inert metals. (Iron, for instance, would oxidize, and thus decrease the amount of oxygen given off.) The theoretical maximum efficiency (electricity used vs. energetic value of hydrogen produced) is in the range 8094%.

Now answer this question: Where does the gaseous oxygen form at?

Output: anode

Input: Article: Corruption is often most evident in countries with the smallest per capita incomes, relying on foreign aid for health services. Local political interception of donated money from overseas is especially prevalent in Sub-Saharan African nations, where it was reported in the 2006 World Bank Report that about half of the funds that were donated for health usages were never invested into the health sectors or given to those needing medical attention.

Now answer this question: Where is corruption most noticeable?

Output: countries with the smallest per capita incomes

Input: Article: Free ISPs are Internet service providers that provide service free of charge. Many free ISPs display advertisements while the user is connected; like commercial television, in a sense they are selling the user's attention to the advertiser. Other free ISPs, sometimes called freenets, are run on a nonprofit basis, usually with volunteer staff.[citation needed]

Now answer this question: What are free ISPs?

Output:
Internet service providers that provide service free of charge
