Here is a question about this article: 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.
What is the answer to this question: When was Neptune first observed?
****
So... 23 September 1846

Problem: Please answer a question about the following article about Dissolution of the Soviet Union:
From mid-May to September 1989, Ukrainian Greek-Catholic hunger strikers staged protests on Moscow's Arbat to call attention to the plight of their Church. They were especially active during the July session of the World Council of Churches held in Moscow. The protest ended with the arrests of the group on September 18. On May 27, 1989, the founding conference of the Lviv regional Memorial Society was held. On June 18, 1989, an estimated 100,000 faithful participated in public religious services in Ivano-Frankivsk in western Ukraine, responding to Cardinal Myroslav Lubachivsky's call for an international day of prayer.
What were the hunger strikers hoping to draw attention to?
A: plight of their Church.

On December 21, 1968, Frank Borman, James Lovell, and William Anders became the first humans to ride the Saturn V rocket into space on Apollo 8. They also became the first to leave low-Earth orbit and go to another celestial body, and entered lunar orbit on December 24. They made ten orbits in twenty hours, and transmitted one of the most watched TV broadcasts in history, with their Christmas Eve program from lunar orbit, that concluded with a reading from the biblical Book of Genesis. Two and a half hours after the broadcast, they fired their engine to perform the first trans-Earth injection to leave lunar orbit and return to the Earth. Apollo 8 safely landed in the Pacific ocean on December 27, in NASA's first dawn splashdown and recovery.

Which ocean did the Apolo 8 mission land in?
Answer: Pacific

An additional 4.6 billion tonnes of uranium are estimated to be in sea water (Japanese scientists in the 1980s showed that extraction of uranium from sea water using ion exchangers was technically feasible). There have been experiments to extract uranium from sea water, but the yield has been low due to the carbonate present in the water. In 2012, ORNL researchers announced the successful development of a new absorbent material dubbed HiCap which performs surface retention of solid or gas molecules, atoms or ions and also effectively removes toxic metals from water, according to results verified by researchers at Pacific Northwest National Laboratory.
Where were ORNL's results verified?
