Input: Read this: However, early farmers were also adversely affected in times of famine, such as may be caused by drought or pests. In instances where agriculture had become the predominant way of life, the sensitivity to these shortages could be particularly acute, affecting agrarian populations to an extent that otherwise may not have been routinely experienced by prior hunter-gatherer communities. Nevertheless, agrarian communities generally proved successful, and their growth and the expansion of territory under cultivation continued.
Question: What were the causes of cultivation in early farm towns?

Output: unanswerable

QUES: Starting in mid-June 1944, Iwo Jima came under sustained aerial bombardment and naval artillery fire. However, Kuribayashi's hidden guns and defenses survived the constant bombardment virtually unscathed. On 19 February 1945, some 30,000 men of the 3rd, 4th, and 5th Marine Divisions landed on the southeast coast of Iwo, just under Mount Suribachi; where most of the island's defenses were concentrated. For some time, they did not come under fire. This was part of Kuribayashi's plan to hold fire until the landing beaches were full. As soon as the Marines pushed inland to a line of enemy bunkers, they came under devastating machine gun and artillery fire which cut down many of the men. By the end of the day, the Marines reached the west coast of the island, but their losses were appalling; almost 2,000 men killed or wounded.

How many men landed on Iwo Jima on February 19, 1945?
What is the answer?

QUES: For Ruskin, the aesthetic was of overriding significance. His work goes on to state that a building is not truly a work of architecture unless it is in some way "adorned". For Ruskin, a well-constructed, well-proportioned, functional building needed string courses or rustication, at the very least.
What features at minimum did Ruskin insist on for a building to be considered functional?

ANS: string courses or rustication

New York's non-white population was 36,620 in 1890. New York City was a prime destination in the early twentieth century for African Americans during the Great Migration from the American South, and by 1916, New York City was home to the largest urban African diaspora in North America. The Harlem Renaissance of literary and cultural life flourished during the era of Prohibition. The larger economic boom generated construction of skyscrapers competing in height and creating an identifiable skyline.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What was the population of people in New York that were not Caucasian in 1890?
Ah, so.. 36,620

QUES: 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".
What combines "grain radical" with the "mouth radical"?

ANS:
"harmony, peace"
