Problem: The theory of special relativity finds a convenient formulation in Minkowski spacetime, a mathematical structure that combines three dimensions of space with a single dimension of time. In this formalism, distances in space can be measured by how long light takes to travel that distance, e.g., a light-year is a measure of distance, and a meter is now defined in terms of how far light travels in a certain amount of time. Two events in Minkowski spacetime are separated by an invariant interval, which can be either space-like, light-like, or time-like. Events that have a time-like separation cannot be simultaneous in any frame of reference, there must be a temporal component (and possibly a spatial one) to their separation. Events that have a space-like separation will be simultaneous in some frame of reference, and there is no frame of reference in which they do not have a spatial separation. Different observers may calculate different distances and different time intervals between two events, but the invariant interval between the events is independent of the observer (and his velocity).
What will events that have a time-like separation always be in some frame of reference?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Historians agree that Napoleon's remarkable personality was one key to his influence. They emphasize the strength of his ambition that took him from an obscure village to command of most of Europe. George F. E. Rudé stresses his "rare combination of will, intellect and physical vigour." At 5 ft 6 in (168 cm), he was not physically imposing but in one-on-one situations he typically had a hypnotic impact on people and seemingly bent the strongest leaders to his will. He understood military technology, but was not an innovator in that regard. He was an innovator in using the financial, bureaucratic, and diplomatic resources of France. He could rapidly dictate a series of complex commands to his subordinates, keeping in mind where major units were expected to be at each future point, and like a chess master, "seeing" the best plays moves ahead.
How tall was Napoleon, in feet and inches?
A: 5 ft 6 in


Context and question: UNFPA is the world's largest multilateral source of funding for population and reproductive health programs. The Fund works with governments and non-governmental organizations in over 150 countries with the support of the international community, supporting programs that help women, men and young people:

Answer: unanswerable


Question: In its early years Universal released three brands of feature films — Red Feather, low-budget programmers; Bluebird, more ambitious productions; and Jewel, their prestige motion pictures. Directors included Jack Conway, John Ford, Rex Ingram, Robert Z. Leonard, George Marshall and Lois Weber, one of the few women directing films in Hollywood.:13
Is there an answer to this question: What motion pictures were made by Jewel?

Answer: prestige motion pictures


Problem: Genome:

Both the number of base pairs and the number of genes vary widely from one species to another, and there is only a rough correlation between the two (an observation known as the C-value paradox). At present, the highest known number of genes is around 60,000, for the protozoan causing trichomoniasis (see List of sequenced eukaryotic genomes), almost three times as many as in the human genome.

Which organism has the most genes?
---
A:
trichomoniasis
