Problem: Treaty:

In international law and international relations, a protocol is generally a treaty or international agreement that supplements a previous treaty or international agreement. A protocol can amend the previous treaty, or add additional provisions. Parties to the earlier agreement are not required to adopt the protocol. Sometimes this is made clearer by calling it an "optional protocol", especially where many parties to the first agreement do not support the protocol.

Problem: Josip Broz Tito:

Unlike other new communist states in east-central Europe, Yugoslavia liberated itself from Axis domination with limited direct support from the Red Army. Tito's leading role in liberating Yugoslavia not only greatly strengthened his position in his party and among the Yugoslav people, but also caused him to be more insistent that Yugoslavia had more room to follow its own interests than other Bloc leaders who had more reasons (and pressures) to recognize Soviet efforts in helping them liberate their own countries from Axis control. Although Tito was formally an ally of Stalin after World War II, the Soviets had set up a spy ring in the Yugoslav party as early as 1945, giving way to an uneasy alliance.[citation needed]

Who was Tito formally an ally of after WWII?
---
A: Stalin


Problem: IPod:

iPods have been criticized for alleged short life-span and fragile hard drives. A 2005 survey conducted on the MacInTouch website found that the iPod line had an average failure rate of 13.7% (although they note that comments from respondents indicate that "the true iPod failure rate may be lower than it appears"). It concluded that some models were more durable than others. In particular, failure rates for iPods employing hard drives was usually above 20% while those with flash memory had a failure rate below 10%. In late 2005, many users complained that the surface of the first generation iPod Nano can become scratched easily, rendering the screen unusable. A class action lawsuit was also filed. Apple initially considered the issue a minor defect, but later began shipping these iPods with protective sleeves.[citation needed]
