Task: Question Answering
Input (English): Background Paragraph: One of the main causes of extinction is introduction of exotic species into an environment. These exotic and new species can also be called invasive species or non-native species . These non-native species, being new to an area, may not have natural predators in the new habitat, which allows their populations to easily adapt and grow. Invasive species out-compete the native species for resources. Sometimes invasive species are so successful at living in a certain habitat that the native species go extinct ( Figure below ). 
Story: India decided to introduce several exotic species into their environment, while Singapore was very protective of its native species. 
Question: Which country didn't observe that non-native species easily adapt and grow?
Output (English): Singapore.
