The possibility of withdrawal depends on the terms of the treaty and its travaux preparatoire. It has, for example, been held that it is not possible to withdraw from the International Covenant on Civil and Political Rights. When North Korea declared its intention to do this the Secretary-General of the United Nations, acting as registrar, said that original signatories of the ICCPR had not overlooked the possibility of explicitly providing for withdrawal, but rather had deliberately intended not to provide for it. Consequently, withdrawal was not possible.
What two factors determine whether it is possible to withdraw from a treaty?
A: the terms of the treaty and its travaux preparatoire

High-gain antennas have the advantage of longer range and better signal quality, but must be aimed carefully at the other antenna. An example of a high-gain antenna is a parabolic dish such as a satellite television antenna. Low-gain antennas have shorter range, but the orientation of the antenna is relatively unimportant. An example of a low-gain antenna is the whip antenna found on portable radios and cordless phones. Antenna gain should not be confused with amplifier gain, a separate parameter measuring the increase in signal power due to an amplifying device.
What is a measure of how much efficient is improved by adding a device designed to make something stronger?
A: amplifier gain

As Edward was unmarried and had no children, Albert was the heir presumptive to the throne. Less than a year later, on 11 December 1936, Edward VIII abdicated in order to marry his mistress, Wallis Simpson, who was divorced from her first husband and divorcing her second. Edward had been advised by British Prime Minister Stanley Baldwin that he could not remain king and marry a divorced woman with two living ex-husbands. Edward chose abdication in preference to abandoning his marriage plans. Thus Albert became king, a position he was reluctant to accept. The day before the abdication, he went to London to see his mother, Queen Mary. He wrote in his diary, "When I told her what had happened, I broke down and sobbed like a child."
Why was Albert the heir presumptive to the throne?
A: Edward was unmarried and had no children

At the same time, British, French, and Soviet negotiators scheduled three-party talks on military matters to occur in Moscow in August 1939, aiming to define what the agreement would specify should be the reaction of the three powers to a German attack. The tripartite military talks, started in mid-August, hit a sticking point regarding the passage of Soviet troops through Poland if Germans attacked, and the parties waited as British and French officials overseas pressured Polish officials to agree to such terms. Polish officials refused to allow Soviet troops into Polish territory if Germany attacked; as Polish foreign minister Jozef Beck pointed out, they feared that once the Red Army entered their territories, it might never leave.
In what city did the tripartite military talks occur during the month of July?
A:
unanswerable
