Input: Article: Believed to be a stowaway on a U.S. military transport near the end of World War II, the brown tree snake (Boiga irregularis) was accidentally introduced to Guam, that previously had no native species of snake. It nearly eliminated the native bird population. The problem was exacerbated because the reptile has no natural predators on the island. The brown tree snake, known locally as the kulebla, is native to northern and eastern coasts of Australia, Papua New Guinea, and the Solomon Islands. While slightly venomous, the snake is relatively harmless to human beings. Although some studies have suggested a high density of these serpents on Guam, residents rarely see the nocturnal creatures. The United States Department of Agriculture has trained detector dogs to keep the snakes out of the island's cargo flow. The United States Geological Survey also has dogs capable of detecting snakes in forested environments around the region's islands.

Now answer this question: What has the U.S Department of Agriculture done to help watch for the snakes?

Output: has trained detector dogs to keep the snakes out of the island's cargo flow

Input: Article: Daniel Gralath was the first to combine several jars in parallel into a "battery" to increase the charge storage capacity. Benjamin Franklin investigated the Leyden jar and came to the conclusion that the charge was stored on the glass, not in the water as others had assumed. He also adopted the term "battery", (denoting the increasing of power with a row of similar units as in a battery of cannon), subsequently applied to clusters of electrochemical cells. Leyden jars were later made by coating the inside and outside of jars with metal foil, leaving a space at the mouth to prevent arcing between the foils.[citation needed] The earliest unit of capacitance was the jar, equivalent to about 1.11 nanofarads.

Now answer this question: Who coined the term "battery"?

Output: Benjamin Franklin

Input: Article: Spielberg next directed the historical drama film Lincoln, starring Daniel Day-Lewis as United States President Abraham Lincoln and Sally Field as Mary Todd Lincoln. Based on Doris Kearns Goodwin's bestseller Team of Rivals: The Political Genius of Abraham Lincoln, the film covered the final four months of Lincoln's life.

The film's international distribution was handled by 20th Century Fox. Upon release, Lincoln received widespread critical acclaim, and was nominated for twelve Academy Awards (the most of any film that year) including Best Picture and Best Director for Spielberg. It won the award for Best Production Design and Day-Lewis won the Academy Award for Best Actor for his portrayal of Lincoln, becoming the first three time winner in that category as well as the first to win for a performance directed by Spielberg.
