Task: Question Generation
Input (English): Background Paragraph: Plants called epiphytes grow on other plants. They obtain moisture from the air and make food by photosynthesis. Most epiphytes are ferns or orchids that live in tropical or temperate rainforests (see Figure below ). Host trees provide support, allowing epiphyte plants to obtain air and sunlight high above the forest floor. Being elevated above the ground lets epiphytes get out of the shadows on the forest floor so they can get enough sunlight for photosynthesis. Being elevated may also reduce the risk of being eaten by herbivores and increase the chance of pollination by wind. 
Story: Emily's father is very sick, After doing some research she finds that a rare medicinal herb can help her father and is located in a nearby forest. The only information she is able to uncover about the herb other than it's effect is that it is an epiphyte. She decides to spend a day looking for the herb.
Output (English): Given Emily climbs to the top of a tree, will she have a higher or lower chance of locating the herb?
