Task: Question Answering
Input (English): passage: Pollination of fruit trees is required to produce seeds with surrounding fruit. It is the process of moving pollen from the anther to the stigma, either in the same flower or in another flower. Some tree species, including many fruit trees, do not produce fruit from self-pollination, so pollinizer trees are planted in orchards.
 question: do flowers need to be pollinated to produce fruit?
Output (English): Yes
