Based on the information present in the given passage, you need to write a correct answer to the given question. A correct answer is one that correctly and completely answers the question. Do not write answers that address the question partially or incorrectly. The correct answer must be contained in the given paragraph.

Example Input: Paragraph- Sent 1: Unfortunately, because the zooming is rather fast, it is easy to miss the rest of the sentence, so as you correctly note, some viewers got an incorrect impression.
Sent 2: It would have been fair for Moore to point out this possible misinterpretation on his website.
Sent 3: However, the claim of deliberate distortion is ludicrous for several reasons: a) Moore clearly states that "before he came to Flint", Heston gave an interview.
Sent 4: In the excerpt from said interview, we can see that it is from March.
Sent 5: If Moore wanted to deceive his viewers, why would he say this, and show the month the interview was published?
Sent 6: b) Why should Moore leave the words "Clinton is on the Today Show" visible in the text, which is necessary to correctly interpret the highlighted part?
Sent 7: I reviewed the sequence several times and it is perfectly possible to see this text without pausing.
Sent 8: c) Both the "soccer mom" interview and the sequences showing the NRA rally make no effort to distort the fact that this rally happened months after the fact.
Sent 9: The camera lingers on Bush/Cheney posters, and the protestor is quoted as saying that "we wanted to let the NRA know that we haven't forgotten about Kayla Rolland".
Sent 10: You make the hysterical claim that the interview "may be faked" (on the basis that no name is shown for the interviewee), but if Moore had faked it, why the hell should he put this sentence in the protestor's mouth, which directly contradicts the conclusion that the rally happened hours after Kayla's death?
Sent 11: Why did Moore, the masterful deveiver, not edit this sequence out?
Sent 12: This makes no sense.
Sent 13: Opinions may vary on how tasteless it was for Heston to hold a pro gun rally on the location of the nation's youngest school shooting months after the fact, but this sequence of "Bowling" is without doubt the most unfair to Heston.
Sent 14: The claims of deliberate distortion don't hold up when viewing the whole scene, though -- as "Hanlon's Razor" states, one should never attribute to malice what can be attributed to incompetence.
Sent 15: The somewhat inept editing of the NRA press release has led some viewers to wrong conclusions, which is unfortunate, but Moore's critics have no interest in viewing the matter fairly.
Sent 16: Had they done so, Moore himself would probably have apologized for the gaffe.
Sent 17: In any case, at no point does Moore make a false statement, in contradiction to claims by critics that his documentary is "full of lies".
Question: When did Heston give an interview?.
Example Output: Before he came to Flint.

Example Input: Paragraph- Sent 1: On a busy Friday morning in Manhattan, nine pedestrians suffered bullet or fragment wounds after police unleashed a hail of gunfire at a man wielding a .45 caliber pistol who had just killed a former co-worker.

Sent 8: It holds eight, Kelly said.
Sent 9: Police identified the slain co-worker as Steven Ercolino, 41, who had apparently filed a prior complaint against his assailant, claiming that he thought Johnson would eventually try to kill him.
Sent 10: Both men had filed harassment complaints against each other in April 2011, Kelly added.
Sent 11: Ercolino was listed as a vice president of sales at Hazan Import Corp., according to his LinkedIn profile.

Example Input: Paragraph- Sent 1: To make certain the U.S. was aware of the danger, in July 1939, a few months before the beginning of World War II in Europe, Szilard and Wigner visited Einstein to explain the possibility of atomic bombs, which Einstein, a pacifist, said he had never considered.
Sent 2: He was asked to lend his support by writing a letter, with Szilard, to President Roosevelt, recommending the U.S. pay attention and engage in its own nuclear weapons research.
Sent 3: A secret German facility, apparently the largest of the Third Reich, covering 75 acres in an underground complex, was being re-excavated in Austria in December 2014 and may have been planned for use in nuclear research and development.
Sent 4: The letter is believed to be "arguably the key stimulus for the U.S. adoption of serious investigations into nuclear weapons on the eve of the U.S. entry into World War II".
Sent 5: In addition to the letter, Einstein used his connections with the Belgian Royal Family and the Belgian queen mother to get access with a personal envoy to the White House's Oval Office.
Sent 6: President Roosevelt could not take the risk of allowing Hitler to possess atomic bombs first.
Sent 7: As a result of Einstein's letter and his meetings with Roosevelt, the U.S. entered the "race" to develop the bomb, drawing on its "immense material, financial, and scientific resources" to initiate the Manhattan Project.
Sent 8: It became the only country to successfully develop an atomic bomb during World War II.
Sent 9: For Einstein, "war was a disease ... [and] he called for resistance to war."Sent 10: By signing the letter to Roosevelt he went against his pacifist principles.
Sent 11: In 1954, a year before his death, Einstein said to his old friend, Linus Pauling, "I made one great mistake in my life--when I signed the letter to President Roosevelt recommending that atom bombs be made; but there was some justification--the danger that the Germans would make them ...".
Question: What was arguably the key stimulus for the U.S. adoption of serious investigations into nuclear weapons on the eve of the U.S. entry into World War II?.
Example Output:
Einstein's letter.
