Passage: Due to the expansion of trade and its geographical proximity, Kiev became the most important trade centre and chief among the communes; therefore the leader of Kiev gained political "control" over the surrounding areas. This princedom emerged from a coalition of traditional patriarchic family communes banded together in an effort to increase the applicable workforce and expand the productivity of the land. This union developed the first major cities in the Rus' and was the first notable form of self-government. As these communes became larger, the emphasis was taken off the family holdings and placed on the territory that surrounded. This shift in ideology became known as the verv'. Question: How did the leader of Kiev gain political control?
Due to the expansion of trade

Passage: In October 1997, Nintendo released a redesigned model of the SNES (the SNS-101 model) in North America for US$99, which sometimes included the pack-in game Super Mario World 2: Yoshi's Island.

A similarly redesigned Super Famicom Jr. was released in Japan at around the same time. Question: How much did the SNS-101 cost in the US?
US$99

Passage: Modified radicals and new variants are two common reasons for the ever-increasing number of characters. There are about 300 radicals and 100 are in common use. Creating a new character by modifying the radical is an easy way to disambiguate homographs among xingshengzi pictophonetic compounds. This practice began long before the standardization of Chinese script by Qin Shi Huang and continues to the present day. The traditional 3rd-person pronoun ta ( "he, she, it"), which is written with the "person radical", illustrates modifying significs to form new characters. In modern usage, there is a graphic distinction between ta ( "she") with the "woman radical", ta ( "it") with the "animal radical", ta ( "it") with the "roof radical", and ta ( "He") with the "deity radical", One consequence of modifying radicals is the fossilization of rare and obscure variant logographs, some of which are not even used in Classical Chinese. For instance, he "harmony, peace", which combines the "grain radical" with the "mouth radical", has infrequent variants with the radicals reversed and with the "flute radical". Question: What is one consequence of modifying radicals?
fossilization
