Input: Read this: President Abraham Lincoln visited General Grant at Petersburg on April 3, and took a launch to Richmond the next day, while Jefferson Davis attempted to organize his Confederate government at Danville. Lincoln met Confederate assistant secretary of War John A. Campbell, and handed him a note inviting Virginia's legislature to end their rebellion. After Campbell spun the note to Confederate legislators as a possible end to the Emancipation Proclamation, Lincoln rescinded his offer and ordered General Weitzel to prevent the Confederate state legislature from meeting. Union forces killed, wounded or captured 8000 Confederate troops at Saylor's Creek southwest of Petersburg on April 6. General Lee continued to reject General Grant's surrender suggestion until Sheridan's infantry and cavalry appeared in front of his retreating army on April 8. He surrendered his remaining approximately 10000 troops at Appomattox Court House the following morning. Jefferson Davis retreated to North Carolina, then further south. when Lincoln rejected the surrender terms negotiated by general Sherman and envoys of North Carolina governor Zebulon Vance, which failed to mention slavery. Davis was captured on May 10 near Irwinville, Georgia and taken back to Virginia, where he was charged with treason and imprisoned for two years at Fort Monroe until freed on bail.
Question: In what structure did Lee surrender to Grant?

Output: Appomattox Court House


QUES: High, cold ice clouds such as Cirrus or Cumulonimbus show up bright white, lower warmer clouds such as Stratus or Stratocumulus show up as grey with intermediate clouds shaded accordingly. Hot land surfaces will show up as dark-grey or black. One disadvantage of infrared imagery is that low cloud such as stratus or fog can be a similar temperature to the surrounding land or sea surface and does not show up. However, using the difference in brightness of the IR4 channel (10.3–11.5 µm) and the near-infrared channel (1.58–1.64 µm), low cloud can be distinguished, producing a fog satellite picture. The main advantage of infrared is that images can be produced at night, allowing a continuous sequence of weather to be studied.

What color are Strarus clouds in infrared?
What is the answer?
ANS: grey


QUES: Only a few contemporary societies are classified as hunter-gatherers, and many supplement their foraging activity with horticulture and/or keeping animals.
Which societies replace foraging with horticulture and/or keeping animals?

ANS: unanswerable


Zhejiang was the site of the Neolithic cultures of the Hemudu and Liangzhu. A 2007 analysis of the DNA recovered from human remains in the archeological sites of prehistoric peoples along the Yangtze River shows high frequencies of haplogroup O1 in the Liangzhu culture, linking them to Austronesian and Tai-Kadai peoples.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What kind of cultures were the Hemudu and Liangzhu?
Ah, so.. Neolithic


Question: Victoria's youngest son, Leopold, was affected by the blood-clotting disease haemophilia B and two of her five daughters, Alice and Beatrice, were carriers. Royal haemophiliacs descended from Victoria included her great-grandsons, Tsarevich Alexei of Russia, Alfonso, Prince of Asturias, and Infante Gonzalo of Spain. The presence of the disease in Victoria's descendants, but not in her ancestors, led to modern speculation that her true father was not the Duke of Kent but a haemophiliac. There is no documentary evidence of a haemophiliac in connection with Victoria's mother, and as male carriers always suffer the disease, even if such a man had existed he would have been seriously ill. It is more likely that the mutation arose spontaneously because Victoria's father was over 50 at the time of her conception and haemophilia arises more frequently in the children of older fathers. Spontaneous mutations account for about a third of cases.
Try to answer this question if possible: In how many births do spontaneous cases of haemophilia arise?
Answer: about a third of cases


Problem: Not all of these cultural elements characteristic of the Neolithic appeared everywhere in the same order: the earliest farming societies in the Near East did not use pottery. In other parts of the world, such as Africa, South Asia and Southeast Asia, independent domestication events led to their own regionally distinctive Neolithic cultures that arose completely independent of those in Europe and Southwest Asia. Early Japanese societies and other East Asian cultures used pottery before developing agriculture.
Where did independent domestication events lead to their own cultures?
