question:  Which of these does Dr. Niemand believe to be true about the timing of the attacks?
context: This, be it understood, is fiction—nothing but fiction—and not, under any circumstances, to be considered as having any truth whatever to it. In the closing days of December, 1957, at the meeting of the American Association for the Advancement of Science in New York, Dr. Niemand delivered a paper entitled simply, "On the Nature of the Solar S-Regions." These implications are discussed here in an exclusive interview with Dr. Niemand by Philip Latham. I suppose you might say my main job today is to find out all I can between activity on the Sun and various forms of activity on the Earth. What do you mean by activity on the Sun? NIEMAND. Just what is a sunspot? I'm afraid I can't say just what a sunspot is. Isn't it true that the number of spots on the Sun rises and falls in a cycle of eleven years? It means you can only approximately predict the future course of sunspot activity. Haven't there been a great many correlations announced between sunspots and various effects on the Earth? There is unquestionably a correlation between sunspots and disturbances of the Earth's magnetic field ... Now, Dr. Niemand, I understand that you have been investigating solar and terrestrial relationships along rather unorthodox lines. I think our biggest advance was the discovery that sunspots themselves are not the direct cause of the disturbances we have been studying on the Earth. Whereas the real cause is an invisible filterable virus. In the solar case it turned out to be these S-Regions. It is extremely doubtful, however, if the radiation we detect is the actual cause of the disturbing effects observed. In the Sun? NIEMAND. Philosophers have wrestled with it ever since the days of Job. The truth of the matter is that men go to war because they want to go to war. They are impelled by forces over which they have no control. Such a syndrome is characteristic of menopausal women and some men during the climacteric, but these people failed to fit into this picture.
output:  They are related to the sun's cycle and the speed at which S-Regions travel
options:  They are related to sunspots and the speed of the Earth's rotation  Overcast weather throws off the timing of paired attacks in different areas  The timing of the events depends on the movement of the moon, like tides of oceans  They are related to the sun's cycle and the speed at which S-Regions travel
