Article: The signatures of the parties' representatives follow at the very end. When the text of a treaty is later reprinted, such as in a collection of treaties currently in effect, an editor will often append the dates on which the respective parties ratified the treaty and on which it came into effect for each party.

Question: Each party must have done what in order for the treaty to come into effect?
Ans: ratified the treaty


Here is a question about this article: Records of bird migration were made as much as 3,000 years ago by the Ancient Greek writers Hesiod, Homer, Herodotus and Aristotle. The Bible also notes migrations, as in the Book of Job (39:26), where the inquiry is made: "Is it by your insight that the hawk hovers, spreads its wings southward?" The author of Jeremiah (8:7) wrote: "Even the stork in the heavens knows its seasons, and the turtle dove, the swift and the crane keep the time of their arrival."
What is the answer to this question: What bird is mentioned in the book of Job?

The problem: Answer a question about this article:
On 10 October 2009, Armenia and Turkey signed protocols on normalisation of relationships, which set a timetable for restoring diplomatic ties and reopening their joint border. The ratification of those had to be made in the national parliaments. In Armenia it passed through the required by legislation approval of the Constitutional Court and was sent to the parliament for the final ratification. The President had made multiple public announcements, both in Armenia and abroad, that as the leader of the political majority of Armenia he assured the ratification of the protocols if Turkey also ratified them. Despite this, the process stopped, as Turkey continuously added more preconditions to its ratification and also "delayed it beyond any reasonable time-period".
Who ratifies protocols in Armenia?
****
The answer: national parliaments


Problem: Please answer a question about the following article about Electric motor:
Because the rotor is much lighter in weight (mass) than a conventional rotor formed from copper windings on steel laminations, the rotor can accelerate much more rapidly, often achieving a mechanical time constant under one ms. This is especially true if the windings use aluminum rather than the heavier copper. But because there is no metal mass in the rotor to act as a heat sink, even small coreless motors must often be cooled by forced air. Overheating might be an issue for coreless DC motor designs.
The lack of a metal mass in the core causes what function to be absent?
A: heat sink


Question: Read this and answer the question

The ammunition and shells fired by these weapons are usually fitted with different types of fuses (barometric, time-delay, or proximity) to explode close to the airborne target, releasing a shower of fast metal fragments. For shorter-range work, a lighter weapon with a higher rate of fire is required, to increase a hit probability on a fast airborne target. Weapons between 20 mm and 40 mm caliber have been widely used in this role. Smaller weapons, typically .50 caliber or even 8 mm rifle caliber guns have been used in the smallest mounts.

What are two types of fuses used for shells?
Answer: barometric, time-delay, or proximity


The earliest examples of visual representations in Iranian history are traced back to the bas-reliefs of Persepolis, c. 500 BC. Persepolis was the ritual center of the ancient kingdom of Achaemenids, and the figures at Persepolis remain bound by the rules of grammar and syntax of visual language. The Iranian visual arts reached a pinnacle by the Sassanid Era. A bas-relief from this period in Taq Bostan depicts a complex hunting scene. Similar works from the period have been found to articulate movements and actions in a highly sophisticated manner. It is even possible to see a progenitor of the cinema close-up in one of these works of art, which shows a wounded wild pig escaping from the hunting ground.
How far back can the first known examples of Iranian visual art be traced to?
c. 500 BC
