Input: American Idol
The top 10 contestants started with five males and five females, however, the males were eliminated consecutively in the first five weeks, with Lazaro Arbos the last male to be eliminated. For the first time in the show's history, the top 5 contestants were all female. It was also the first time that the judges' "save" was not used, the top four contestants were therefore given an extra week to perform again with their votes carried over with no elimination in the first week.

How many contestants did this season have?
Output: 10

Input: House music
With house music already massive on the '80s dance-scene it was only a matter of time before it would penetrate the UK pop charts.[citation needed] The record generally credited as the first house hit in the UK was Farley "Jackmaster" Funk's "Love Can't Turn Around" which reached #10 in the UK singles chart in September 1986.

what is credited as the first house hit in the UK?

Input: Biodiversity
The number of species invasions has been on the rise at least since the beginning of the 1900s. Species are increasingly being moved by humans (on purpose and accidentally). In some cases the invaders are causing drastic changes and damage to their new habitats (e.g.: zebra mussels and the emerald ash borer in the Great Lakes region and the lion fish along the North American Atlantic coast). Some evidence suggests that invasive species are competitive in their new habitats because they are subject to less pathogen disturbance. Others report confounding evidence that occasionally suggest that species-rich communities harbor many native and exotic species simultaneously while some say that diverse ecosystems are more resilient and resist invasive plants and animals. An important question is, "do invasive species cause extinctions?" Many studies cite effects of invasive species on natives, but not extinctions. Invasive species seem to increase local (i.e.: alpha diversity) diversity, which decreases turnover of diversity (i.e.: beta diversity). Overall gamma diversity may be lowered because species are going extinct because of other causes, but even some of the most insidious invaders (e.g.: Dutch elm disease, emerald ash borer, chestnut blight in North America) have not caused their host species to become extinct. Extirpation, population decline, and homogenization of regional biodiversity are much more common. Human activities have frequently been the cause of invasive species circumventing their barriers, by introducing them for food and other purposes. Human activities therefore allow species to migrate to new areas (and thus become invasive) occurred on time scales much shorter than historically have been required for a species to extend its range.

What invaders are causing changes along the North American Atlantic coast?
Output: lion fish

Input: Hellenistic period
The spread of Greek culture and language throughout the Near East and Asia owed much to the development of newly founded cities and deliberate colonization policies by the successor states, which in turn was necessary for maintaining their military forces. Settlements such as Ai-Khanoum, situated on trade routes, allowed Greek culture to mix and spread. The language of Philip II's and Alexander's court and army (which was made up of various Greek and non-Greek speaking peoples) was a version of Attic Greek, and over time this language developed into Koine, the lingua franca of the successor states.

Ai-Khanoum was situated on what kind of routes?
Output:
trade
