Question: What can products not use if they want to avoid infringing on patent rights?

Output: the [MPEG Layer-3] standard

Input: Read this: On the day of the abdication, the Oireachtas, the parliament of the Irish Free State, removed all direct mention of the monarch from the Irish constitution. The next day, it passed the External Relations Act, which gave the monarch limited authority (strictly on the advice of the government) to appoint diplomatic representatives for Ireland and to be involved in the making of foreign treaties. The two acts made the Irish Free State a republic in essence without removing its links to the Commonwealth.
Question: Who abdicated?

Output: unanswerable

Input: Read this: In the private sector, corruption increases the cost of business through the price of illicit payments themselves, the management cost of negotiating with officials and the risk of breached agreements or detection. Although some claim corruption reduces costs by cutting bureaucracy, the availability of bribes can also induce officials to contrive new rules and delays. Openly removing costly and lengthy regulations are better than covertly allowing them to be bypassed by using bribes. Where corruption inflates the cost of business, it also distorts the playing field, shielding firms with connections from competition and thereby sustaining inefficient firms.
Question: Corruption changes the playing field by allowing businesses with connections to be shielded by what?

Output:
competition
