Problem: Please answer a question about the following article about Daylight saving time:
DST is generally not observed near the equator, where sunrise times do not vary enough to justify it. Some countries observe it only in some regions; for example, southern Brazil observes it while equatorial Brazil does not. Only a minority of the world's population uses DST because Asia and Africa generally do not observe it.
Which part of Brazil observes Daylight Saving Time?
A: southern Brazil

Neptune is not visible to the unaided eye and is the only planet in the Solar System found by mathematical prediction rather than by empirical observation. Unexpected changes in the orbit of Uranus led Alexis Bouvard to deduce that its orbit was subject to gravitational perturbation by an unknown planet. Neptune was subsequently observed with a telescope on 23 September 1846 by Johann Galle within a degree of the position predicted by Urbain Le Verrier. Its largest moon, Triton, was discovered shortly thereafter, though none of the planet's remaining known 14 moons were located telescopically until the 20th century. The planet's distance from Earth gives it a very small apparent size, making it challenging to study with Earth-based telescopes. Neptune was visited by Voyager 2, when it flew by the planet on 25 August 1989. The advent of Hubble Space Telescope and large ground-based telescopes with adaptive optics has recently allowed for additional detailed observations from afar.

How was Neptune found?
Answer: mathematical prediction

Problem: The variance in prevalence rates is reflected in people's inconsistent responses to the different components of sexual orientation within a study and the instability of their responses over time. Laumann et al., (1994) found that among U.S. adults 20% of those who would be considered homosexual on one component of orientation were homosexual on the other two dimensions and 70% responded in a way that was consistent with homosexuality on only one of the three dimensions. Furthermore, sexuality is fluid such that one's sexual orientation is not necessarily stable or consistent over time but is subject to change throughout life. Diamond (2003) found that over 7 years 2/3 of the women changed their sexual identity at least once, with many reporting that the label was not adequate in capturing the diversity of their sexual or romantic feelings. Furthermore, women who relinquished bisexual and lesbian identification did not relinquish same sex sexuality and acknowledged the possibility for future same sex attractions and/or behaviour. One woman stated "I'm mainly straight but I'm one of those people who, if the right circumstance came along, would change my viewpoint". Therefore, individuals classified as homosexual in one study might not be identified the same way in another depending on which components are assessed and when the assessment is made making it difficult to pin point who is homosexual and who is not and what the overall prevalence within a population may be.
What did Diamond find about the women?
The answer is the following: over 7 years 2/3 of the women changed their sexual identity at least once,

Frederic Francois Chopin (/opn/; French pronunciation: [fe.de.ik f.swa .p]; 22 February or 1 March 1810 17 October 1849), born Fryderyk Franciszek Chopin,[n 1] was a Polish and French (by citizenship and birth of father) composer and a virtuoso pianist of the Romantic era, who wrote primarily for the solo piano. He gained and has maintained renown worldwide as one of the leading musicians of his era, whose "poetic genius was based on a professional technique that was without equal in his generation." Chopin was born in what was then the Duchy of Warsaw, and grew up in Warsaw, which after 1815 became part of Congress Poland. A child prodigy, he completed his musical education and composed his earlier works in Warsaw before leaving Poland at the age of 20, less than a month before the outbreak of the November 1830 Uprising.
When did Chopin die?
17 October 1849

Input: Han dynasty
Though Han wooden structures decayed, some Han-dynasty ruins made of brick, stone, and rammed earth remain intact. This includes stone pillar-gates, brick tomb chambers, rammed-earth city walls, rammed-earth and brick beacon towers, rammed-earth sections of the Great Wall, rammed-earth platforms where elevated halls once stood, and two rammed-earth castles in Gansu. The ruins of rammed-earth walls that once surrounded the capitals Chang'an and Luoyang still stand, along with their drainage systems of brick arches, ditches, and ceramic water pipes. Monumental stone pillar-gates, twenty-nine of which survive from the Han period, formed entrances of walled enclosures at shrine and tomb sites. These pillars feature artistic imitations of wooden and ceramic building components such as roof tiles, eaves, and balustrades.

What architectural feature contained an imitation of a balustrade?
Output: stone pillar-gates

Problem: Please answer a question about the following article about Josip Broz Tito:
His next relationship was with Herta Haas, whom he married in 1940. Broz left for Belgrade after the April War, leaving Haas pregnant. In May 1941, she gave birth to their son, Aleksandar "Miso" Broz. All throughout his relationship with Haas, Tito had maintained a promiscuous life and had a parallel relationship with Davorjanka Paunovic, who, under the codename "Zdenka", served as a courier in the resistance and subsequently became his personal secretary. Haas and Tito suddenly parted company in 1943 in Jajce during the second meeting of AVNOJ after she reportedly walked in on him and Davorjanka. The last time Haas saw Broz was in 1946. Davorjanka died of tuberculosis in 1946 and Tito insisted that she be buried in the backyard of the Beli Dvor, his Belgrade residence.
When did Haas give birth to Tito's son?
A:
1941
