The rest of the Cullens and Jacob stay nearby, and when Jacob acts possessively towards Renesmee, Bella learns he has imprinted on her, making her furious until Jacob explains what imprinting is. Meanwhile, Bella's father, Charlie, has been trying to contact the Cullens for updates on Bella's health. Carlisle comes to believe that they have to leave Forks, Washington to protect their identities - especially because of Charlie. Jacob, desperate not to lose Renesmee, visits Charlie and tell him that Bella is alive and well, but had to change in order to get better. Jacob also tells Charlie he doesn't live in the world he thinks he lives in, but says nothing about vampires. He then phases into his wolf form.

question:
Passage: In 1565, the powerful Rinbung princes were overthrown by one of their own ministers, Karma Tseten who styled himself as the Tsangpa, "the one of Tsang", and established his base of power at Shigatse. The second successor of this first Tsang king, Karma Phuntsok Namgyal, took control of the whole of Central Tibet (Ü-Tsang), reigning from 1611–1621. Despite this, the leaders of Lhasa still claimed their allegiance to the Phagmodru as well as the Gelug, while the Ü-Tsang king allied with the Karmapa. Tensions rose between the nationalistic Ü-Tsang ruler and the Mongols who safeguarded their Mongol Dalai Lama in Lhasa. The fourth Dalai Lama refused to give an audience to the Ü-Tsang king, which sparked a conflict as the latter began assaulting Gelug monasteries. Chen writes of the speculation over the fourth Dalai Lama's mysterious death and the plot of the Ü-Tsang king to have him murdered for "cursing" him with illness, although Chen writes that the murder was most likely the result of a feudal power struggle. In 1618, only two years after Yonten Gyatso died, the Gelug and the Karma Kargyu went to war, the Karma Kargyu supported by the secular Ü-Tsang king. The Ü-Tsang ruler had a large number of Gelugpa lamas killed, occupied their monasteries at Drepung and Sera, and outlawed any attempts to find another Dalai Lama. In 1621, the Ü-Tsang king died and was succeeded by his young son Karma Tenkyong, an event which stymied the war effort as the latter accepted the six-year-old Lozang Gyatso as the new Dalai Lama. Despite the new Dalai Lama's diplomatic efforts to maintain friendly relations with the new Ü-Tsang ruler, Sonam Rapten (1595–1657), the Dalai Lama's chief steward and treasurer at Drepung, made efforts to overthrow the Ü-Tsang king, which led to another conflict. In 1633, the Gelugpas and several thousand Mongol adherents defeated the Ü-Tsang king's troops near Lhasa before a peaceful negotiation was settled. Goldstein writes that in this the "Mongols were again playing a significant role in Tibetan affairs, this time as the military arm of the Dalai Lama.".
answer:
Who began assaulting Gelug monasteries?


question:
Passage: Lissitzky was born on November 23, 1890 in Pochinok, a small Jewish community 50 kilometres (31 mi) southeast of Smolensk, former Russian Empire. During his childhood, he lived and studied in the city of Vitebsk, now part of Belarus, and later spent 10 years in Smolensk living with his grandparents and attending the Smolensk Grammar School, spending summer vacations in Vitebsk. Always expressing an interest and talent in drawing, he started to receive instruction at 13 from Yehuda Pen, a local Jewish artist, and by the time he was 15 was teaching students himself. In 1909, he applied to an art academy in Saint Petersburg, but was rejected. While he passed the entrance exam and was qualified, the law under the Tsarist regime only allowed a limited number of Jewish students to attend Russian schools and universities.
Like many other Jews then living in the Russian Empire, Lissitzky went to study in Germany. He left in 1909 to study architectural engineering at a Technische Hochschule in Darmstadt, Germany. During the summer of 1912, Lissitzky, in his own words, "wandered through Europe", spending time in Paris and covering 1,200 kilometres (750 mi) on foot in Italy, teaching himself about fine art and sketching architecture and landscapes that interested him. His interest in ancient Jewish culture had originated during the contacts with a Paris-based group of Russian Jews led by sculptor Ossip Zadkine, a lifetime friend of Lissitzky since early childhood, who exposed Lissitzky to conflicts between different groups within the diaspora. Also in 1912 some of his pieces were included for the first time in an exhibit by the St. Petersburg Artists Union; a notable first step. He remained in Germany until the outbreak of World War I, when he was forced to return home through Switzerland and the Balkans, along with many of his countrymen, including other expatriate artists born in the former Russian Empire, such as Wassily Kandinsky and Marc Chagall.Upon his return to Moscow, Lissitzky attended the Polytechnic Institute of Riga, which had been evacuated to Moscow because of the war, and worked for the architectural firms of Boris Velikovsky and Roman Klein.  During this work, he took an active and passionate interest in Jewish culture which, after the downfall of the openly antisemitic Tsarist regime, was experiencing a renaissance. The new Provisional Government repealed a decree that prohibited the printing of Hebrew letters and that barred Jews from citizenship. Thus Lissitzky soon devoted himself to Jewish art, exhibiting works by local Jewish artists, traveling to Mahilyow to study the traditional architecture and ornaments of old synagogues, and illustrating many Yiddish children's books. These books were Lissitzky's first major foray in book design, a field that he would greatly greatly influence over the course of his career.
