Relying on an animal to come by is risky. A flower may have to wait a long time for the right animals to come by. What if one never passes close enough to the flower? Hoping the wind will blow is also risky for a plant. What if the wind does not blow? What if the blowing pollen does not land on another flower? The wind could even blow the pollen over the ocean where it is wasted. Giving free nectar is costly. It is not a good use of the plants energy. A plant uses a lot of energy to produce nectar. Some animals may just drink the nectar. They may not carry off any pollen in return. To improve their chances, plants evolved special traits. For example, they developed ways to hide their nectar. Only certain animals were able to get at the plants hidden nectar. These specific animals might be more likely to visit only flowers of the same species. This was also a benefit for some animals. Animals also evolved special traits to get to the nectar.

Question: "What are ways of transferring pollen?"

Answer: "Relying on an animal and hoping the wind will blow"

Response: yes

Triumph and Disaster: The 20th century saw a stupendous release of energies that had been pent up for the 250 years of Tokugawa isolation. By 1930 raw-material production had tripled the figure of 1900, manufactured goods had increased twelve-fold, and heavy industry was galloping towards maturity. Britain led the World War I Ailies in large orders for munitions, while Japan expanded sales of manufactured goods to Asian and other markets cut off from their usual European suppliers. Merchant shipping doubled in size and increased its income ten-fold as the European fleets were destroyed. Setbacks in the 1930s caused by the European postwar slump were only a spur to redouble efforts by diversifying heavy industry into the machine-making, metallurgical, and chemical sectors. Even the terrible 1923 Tokyo earthquake, which cost over 100,000 lives and billions of dollars, provided another stimulus due to the construction boom that followed. Riding the crest of this economic upsurge were the zaibatsu conglomeratesa dozen family-run combines, each involved in mining, manufacturing, marketing, shipping, and banking. These tightly controlled commercial pyramids were the true heirs to the old feudal structures. Japan's progress toward parliamentary democracy was halted in the 1930s by the growing nationalism being imposed on government by the generals and admirals. They proclaimed Japan's mission to bring progress to its backward Asian neighbors in language not so very different from that of the Europeans in Africa or the US in Latin America. After the Russian Revolution of 1917, the Soviet Union was regarded as a major threat to Japan's security, and the army felt it needed Manchuria and whatever other Chinese territory it could control as a buffer against Russian advances. In 1931 the Japanese occupied Manchuria. And then in 1937, with the popular support of ultra-right-wing groups, the army overrode parliamentary resistance in Tokyo and went to war against the Chinese Nationalists. By 1938, they held Nanking, Hankow, and Canton. Japanese expansionist policies were leading to direct confrontation with the West. Japan hoped that war in Europe would divert the Soviet Union from interference in East Asia, giving Japan a free hand both in China and, through its alliance with Germany, in French IndoChina after the defeat of France. The US responded to the Japanese invasion of IndoChina with a trade and fuel embargo, cutting off 90 percent of Japan's supplies. The result was the attack on the American fleet at Pearl Harbor (7 December 1941) and total war.

Question: "What act against Japan resulted in the attack on Pearl Harbor?"

Answer: "Trade embargo"

Response: no

In Hamburg, Jarrah had a succession of living accommodations, but he apparently never resided with his future co-conspirators. It is not clear how and when he became part of Atta's circle. He became particularly friendly with Binalshibh after meeting him at the Quds mosque in Hamburg, which Jarrah began attending regularly in late 1997. The worshippers at this mosque featured an outspoken, flamboyant Islamist named Mohammed Haydar Zammar. A well-known figure in the Muslim community (and to German and U.S. intelligence agencies by the late 1990s), Zammar had fought in Afghanistan and relished any opportunity to extol the virtues of violent jihad. Indeed, a witness has reported hearing Zammar press Binalshibh to fulfill his duty to wage jihad. Moreover, after 9/11, Zammar reportedly took credit for influencing not just Binalshibh but the rest of the Hamburg group. In 1998, Zammar encouraged them to participate in jihad and even convinced them to go to Afghanistan. Owing to Zammar's persuasion or some other source of inspiration, Atta, Binalshibh, Shehhi, and Jarrah eventually prepared themselves to translate their extremist beliefs into action. By late 1999, they were ready to abandon their student lives in Germany in favor of violent jihad. This final stage in their evolution toward embracing Islamist extremism did not entirely escape the notice of the people around them. The foursome became core members of a group of radical Muslims, often hosting sessions at their Marienstrasse apartment that involved extremely anti-American discussions. Meeting three to four times a week, the group became something of a "sect" whose members, according to one participant in the meetings, tended to deal only with each other. Atta's rent checks for the apartment provide evidence of the importance that the apartment assumed as a center for the group, as he would write on them the notation "Dar el Ansar," or "house of the followers." In addition to Atta, Binalshibh, Shehhi, and Jarrah, the group included other extremists, some of whom also would attend al Qaeda training camps and, in some instances, would help the 9/11 hijackers as they executed the plot: Said Bahaji, son of a Moroccan immigrant, was the only German citizen in the group. Educated in Morocco, Bahaji returned to Germany to study electrical engineering at the Technical University of Hamburg-Harburg. He spent five months in the German army before obtaining a medical discharge, and lived with Atta and Binalshibh at 54 Marienstrasse for eight months between November 1998 and July 1999. Described as an insecure follower with no personality and with limited knowledge of Islam, Bahaji nonetheless professed his readiness to engage in violence.

Question: "The four became somewhat of a sect meeting 3 to 4 times a week and what was it that Atta would write on the rent checks?"

Answer: "For every rent check he would write a different message in code"

Response:
no
