Input: Treaty
There are several reasons an otherwise valid and agreed upon treaty may be rejected as a binding international agreement, most of which involve problems created at the formation of the treaty.[citation needed] For example, the serial Japan-Korea treaties of 1905, 1907 and 1910 were protested; and they were confirmed as "already null and void" in the 1965 Treaty on Basic Relations between Japan and the Republic of Korea.

When are most of the problems created that might result in an otherwise valid treaty being rejected as a binding international agreement?
Output: at the formation of the treaty

Input: Hellenistic period
The Egyptians begrudgingly accepted the Ptolemies as the successors to the pharaohs of independent Egypt, though the kingdom went through several native revolts. The Ptolemies took on the traditions of the Egyptian Pharaohs, such as marrying their siblings (Ptolemy II was the first to adopt this custom), having themselves portrayed on public monuments in Egyptian style and dress, and participating in Egyptian religious life. The Ptolemaic ruler cult portrayed the Ptolemies as gods, and temples to the Ptolemies were erected throughout the kingdom. Ptolemy I even created a new god, Serapis, who was combination of two Egyptian gods: Apis and Osiris, with attributes of Greek gods. Ptolemaic administration was, like the Ancient Egyptian bureaucracy, highly centralized and focused on squeezing as much revenue out of the population as possible though tariffs, excise duties, fines, taxes and so forth. A whole class of petty officials, tax farmers, clerks and overseers made this possible. The Egyptian countryside was directly administered by this royal bureaucracy. External possessions such as Cyprus and Cyrene were run by strategoi, military commanders appointed by the crown.

Apis and Osiris combined to make which god?
Output: Serapis

Input: Detroit
Detroit is cited as the birthplace of techno music in the early 1980s. The city also lends its name to an early and pioneering genre of electronic dance music, "Detroit techno". Featuring science fiction imagery and robotic themes, its futuristic style was greatly influenced by the geography of Detroit's urban decline and its industrial past. Prominent Detroit techno artists include Juan Atkins, Derrick May, and Kevin Saunderson. The Detroit Electronic Music Festival, now known as "Movement", occurs annually in late May on Memorial Day Weekend, and takes place in Hart Plaza. In the early years (2000-2002), this was a landmark event, boasting over a million estimated attendees annually, coming from all over the world to celebrate Techno music in the city of its birth.

When does "Movement" occur?
Output: Memorial Day Weekend

Input: PlayStation 3
Tech media website CNET gave new Super Slim 4 out of 5 stars ("Excellent"), saying "The Super Slim PlayStation 3 shrinks a powerful gaming machine into an even tinier package while maintaining the same features as its predecessors: a great gaming library and a strong array of streaming services [...]", whilst also criticising the "cheap" design and disc-loader, stating: "Sometimes [the cover] doesn't catch and you feel like you're using one of those old credit card imprinter machines. In short, it feels cheap. You don't realize how convenient autoloading disc trays are until they're gone. Whether it was to cut costs or save space, this move is ultimately a step back." The criticism also was due to price, stating the cheapest Super Slim model was still more expensive than the cheapest Slim model, and that the smaller size and bigger hard drive shouldn't be considered an upgrade when the hard drive on a Slim model is easily removed and replaced. They did praise that the hard drive of the Super Slim model is "the easiest yet. Simply sliding off the side panel reveals the drive bay, which can quickly be unscrewed." They also stated that whilst the Super Slim model is not in any way an upgrade, it could be an indicator as to what's to come. "It may not be revolutionary, but the Super Slim PS3 is the same impressive machine in a much smaller package. There doesn't seem to be any reason for existing PS3 owners to upgrade, but for the prospective PS3 buyer, the Super Slim is probably the way to go if you can deal with not having a slot-loading disc drive."

What component of the Super Slim did CNET call "the easiest yet"?
Output:
hard drive
