On his return to Nuremberg in 1495, Durer opened his own workshop (being married was a requirement for this). Over the next five years his style increasingly integrated Italian influences into underlying Northern forms. Durer's father died in 1502, and his mother died in 1513. His best works in the first years of the workshop were his woodcut prints, mostly religious, but including secular scenes such as The Men's Bath House (ca. 1496). These were larger and more finely cut than the great majority of German woodcuts hitherto, and far more complex and balanced in composition. It is now thought unlikely that Durer cut any of the woodblocks himself; this task would have been performed by a specialist craftsman. However, his training in Wolgemut's studio, which made many carved and painted altarpieces and both designed and cut woodblocks for woodcut, evidently gave him great understanding of what the technique could be made to produce, and how to work with block cutters. Durer either drew his design directly onto the woodblock itself, or glued a paper drawing to the block. Either way, his drawings were destroyed during the cutting of the block.

Tokugawa Takes All: When Hideyoshi died in 1598, he hoped to have his five-year-old son continue his "dynasty," initially under the tutelage of five regents. But one of the regents was Ieyasu Tokugawa, who had been biding his time at Edo for 12 years, nurturing dynastic ambitions of his own. Of the cunning, ruthless triumvirate that came out on top at the end of the country's century of civil war, Tokugawa was without doubt the most patient, the most prudentand most treacherous. He moved quickly to eliminate his strongest rivals, crushing them in 1600 at the great Battle of Sekigahara (near modern Nagoya). During its subsequent two and a half centuries of rule from the new capital established at Edo, the Tokugawa organized a tightly controlled coalition of some 260 daimyo in strategic strongholds throughout the country. The allegiance of this highly privileged and prestigious group was ensured by cementing their ethical principles in the code of bushido, "The way of the warrior": loyalty to one's master, defense of one's status and honor, and fulfillment of all obligations. Loyalty was further enforced by holding the vassals' wives and children hostage in Edo. All roads into Edo, the most famous being the Tokaido Highway, had checkpoints for guns coming in and for wives going out. One of the most effective ways of keeping a tight rein on the country was to cut it off from the outside world, to keep Japan Japanese. At first, Ieyasu Tokugawa was eager to promote foreign trade. He wanted silk and encouraged the Dutch and British as good, nonproselytizing Protestants just interested in trade. But he didn't like the Portuguese and Spanish Catholic missionaries, who he felt were undermining traditional Japanese values. He banned their activities in 1612 and two years later ordered the expulsion of all missionaries and unrepentant Japanese converts. Executions and torture followed. Converts were forced to renounce their faith by trampling crucifixes and effigies of Jesus and Mary. The Catholic Church has counted 3,125 martyrs in Japan from 1597 (beginning under Hideyoshi) to 1660. In 1635 the Japanese were forbidden, on pain of death, to attempt to travel abroad, and Japanese citizens already overseas were prevented from returning, in case they brought back subversive Christian doctrines. Western books were banned, as were Chinese books that mentioned Christianity.

Question: "What actions did the Tokugawa take towards missionaries and those who converted to Catholicism?"

- no
- yes

Answer: "Banned their activities"

Response: yes

(CNN) -- As Iranian President Mahmoud Ahmadinejad visited the U.N. General Assembly in New York last month, the spotlight was once again on Iran. And true to form, the Iranian president made his fair share of provocative statements for the Western media. But while Ahmadinejad's mercurial rants captured our media's attention, back in Iran a coordinated strategy against the women's movement continued. On the eve of Ahmadinejad's arrival to New York, Shiva Nazar Ahari, a prominent young female defender of human rights, received a heavy sentence of six years in prison on charges including the vague crime of "waging war against God" -- a convenient catch-all offense for anyone who criticizes the regime and its human rights record. There's no denying it -- Iran's women have had a bad year. Nazar Ahari joins a steadily increasing number of other women's rights activists who are in prison for no greater crime than their attempt to fight for the rights of the women. Hengameh Shahidi, Alieh Eghdam Doust, Bahareh Hedayat and Mahdiyeh Golrou have all been sent to Tehran's notorious Evin Prison on trumped-up charges related to their activism. And while Nobel Peace Prize laureate Shirin Ebadi, arguably the most internationally recognized Iranian women's rights activist, remains unable to safely return to her country, the government is targeting those affiliated with her for arrest and imprisonment, including her lawyer Nasrin Sotoudeh and her former aide Jinous Sobhani. Since the 2009 disputed elections and associated government crackdown on the overall reform movement, the government has increasingly targeted women activists. The reasons behind this go well beyond the misogynist nature of Iran's religious leadership. Rather, it is more part of a deliberate and calculated strategy of the Iranian authorities to strike at the heart of the regime's greatest vulnerability -- internal legitimacy with its own people. See more CNN.com opinion articles Iran's government recognizes and fears the broader power of the women activists who have been on the front line of reform in Iran for more than a decade. One can roughly draw an analogy between the women's movement in Iran to movements of religious groups in Burma or Tibet, or the labor "solidarity" movements in the former Eastern bloc and associated labor-Roman Catholic solidarity in Poland -- all advocating initially for the freedoms of a specific group but which provoked government fears for their transformative power to promote broader human rights progress. While the outside world occasionally reacts to the most egregious manifestations of Iran's repression of women -- such as the international condemnation associated with Sakineh Mohammadi Ashtiani, an Iranian widow sentenced to stoning on charges of alleged adultery -- these events are often portrayed simply as a consequence of the regime's archaic viewpoint about gender.

The properties of matter depend on the types of atoms that matter is made of. Matter can exist in two forms. It can be a pure substance. This means it is not mixed with anything. It can also be a combination of different substances. This means it can be a mix of different types of atoms. You may recall that atoms differ based on the numbers of protons they contain. Some atoms contain only one proton such as Hydrogen. Other atoms contain many protons. There are many types of atoms. For example, Helium has two protons. An Oxygen atom has eight. Water is composed of a two types of atoms. Water is made of two Hydrogen atoms and one Oxygen atoms. There are only so many types of atoms. These atoms can be mixed into an almost limitless amount of substances. So what do we call a substance that has only a single type of atom?

Question: "If matter is a pure substance is it mixed with something?"

OPTIONS:
- no
- yes

Answer: "No"

Response:
yes
