The problem: Answer a question about this article:
Current circulating in one antenna generally induces a voltage across the feedpoint of nearby antennas or antenna elements. The mathematics presented below are useful in analyzing the electrical behaviour of antenna arrays, where the properties of the individual array elements (such as half wave dipoles) are already known. If those elements were widely separated and driven in a certain amplitude and phase, then each would act independently as that element is known to. However, because of the mutual interaction between their electric and magnetic fields due to proximity, the currents in each element are not simply a function of the applied voltage (according to its driving point impedance), but depend on the currents in the other nearby elements. Note that this now is a near field phenomenon which could not be properly accounted for using the Friis transmission equation for instance.
Where are the indiviual array elements known?

The answer: antenna arrays

Problem: Please answer a question about the following article about Korean War:
Korea was considered to be part of the Empire of Japan as an industrialized colony along with Taiwan, and both were part of the Greater East Asia Co-Prosperity Sphere. In 1937, the colonial Governor-General, General Jiro Minami, commanded the attempted cultural assimilation of Korea's 23.5 million people by banning the use and study of Korean language, literature, and culture, to be replaced with that of mandatory use and study of their Japanese counterparts. Starting in 1939, the populace was required to use Japanese names under the Soshi-kaimei policy. Conscription of Koreans for labor in war industries began in 1939, with as many as 2 million Koreans conscripted into either the Japanese Army or into the Japanese labor force.
What policy forced Koreans to change their names to Japanese names?
A: Soshi-kaimei policy

During the Partitions of Poland from 1772 to 1795, its members began to lose these legal privileges and social status. From that point until 1918, the legal status of the nobility was essentially dependent upon the policies of the three partitioning powers: the Russian Empire, the Kingdom of Prussia, and the Habsburg Monarchy. The legal privileges of the szlachta were legally abolished in the Second Polish Republic by the March Constitution of 1921.

What was one name of a power that the szlachta was dependent on.
Answer: Russian Empire

Problem: Commercial credit and agricultural consumer loans were the main types of loans. The trade credit was usually extended by temples in order to finance trade expeditions and was nominated in silver. The interest rate was set at 1/60 a month (one shekel per mina) some time before 2000 BC and it remained at that level for about two thousand years. Rural loans commonly arose as a result of unpaid obligations due to an institution (such as a temple), in this case the arrears were considered to be lent to the debtor. They were denominated in barley or other crops and the interest rate was typically much higher than for commercial loans and could amount to 1/3 to 1/2 of the loan principal.
How man shekel per mina was the interest rate for loans?
The answer is the following: one

The River Plym, which flows off Dartmoor to the north-east, forms a smaller estuary to the east of the city called Cattewater. Plymouth Sound is protected from the sea by the Plymouth Breakwater, in use since 1814. In the Sound is Drake's Island which is seen from Plymouth Hoe, a flat public area on top of limestone cliffs. The Unitary Authority of Plymouth is 79.84 square kilometres (30.83 sq mi). The topography rises from sea level to a height, at Roborough, of about 509 feet (155 m) above Ordnance Datum (AOD).
What island is present in Plymouth Sound?
Drake's Island

Here is a question about this article: Pomors are distinguished by the presence of Y Haplogroup N among them. Postulated to originate from southeast Asia, it is found at high rates in Uralic peoples. Its presence in Pomors (called "Northern Russians" in the report) attests to the non-Slavic tribes (mixing with Finnic tribes of northern Eurasia). Autosomally, Russians are generally similar to populations in central-eastern Europe but some northern Russians are intermediate to Finno-Ugric groups.
What is the answer to this question: Y Haplogroup N are found at high rates in who?
****
So...
Uralic peoples
