Input: Read this: The first book printed in France, Epistolae ("Letters"), by Gasparinus de Bergamo (Gasparino da Barzizza), was published in Paris in 1470 by the press established by Johann Heynlin. Since then, Paris has been the centre of the French publishing industry, the home of some of the world's best-known writers and poets, and the setting for many classic works of French literature. Almost all the books published in Paris in the Middle Ages were in Latin, rather than French. Paris did not become the acknowledged capital of French literature until the 17th century, with authors such as Boileau, Corneille, La Fontaine, Moliere, Racine, several coming from the provinces, and the foundation of the Academie francaise. In the 18th century, the literary life of Paris revolved around the cafes and salons, and was dominated by Voltaire, Jean-Jacques Rousseau, Pierre de Marivaux, and Beaumarchais.
Question: Who wrote Epistolae?

Output: Gasparinus de Bergamo

Input: Read this: Immanuel Velikovsky is an example of a recent scientific exoheretic; he did not have appropriate scientific credentials or did not publish in scientific journals. While the details of his work are in scientific disrepute, the concept of catastrophic change (extinction event and punctuated equilibrium) has gained acceptance in recent decades.
Question: What did Velikovsky publish in?

Output: unanswerable

Input: Read this: There are several types of multi-color white LEDs: di-, tri-, and tetrachromatic white LEDs. Several key factors that play among these different methods, include color stability, color rendering capability, and luminous efficacy. Often, higher efficiency will mean lower color rendering, presenting a trade-off between the luminous efficacy and color rendering. For example, the dichromatic white LEDs have the best luminous efficacy (120 lm/W), but the lowest color rendering capability. However, although tetrachromatic white LEDs have excellent color rendering capability, they often have poor luminous efficacy. Trichromatic white LEDs are in between, having both good luminous efficacy (>70 lm/W) and fair color rendering capability.
Question: What is one type of multi-color white LED?

Output:
tetrachromatic
