Task: Question Answering
Input (English): Background Paragraph: The advantage of asexual reproduction is that it can be very quick and does not require the meeting of a male and female organism. The disadvantage of asexual reproduction is that organisms do not receive a mix of traits from both parents. An organism that is born through asexual reproduction only has the DNA from the one parent. In fact, the offspring is genetically an exact copy of the parent. This can cause problems for the individual. For example, if the parent has a gene that causes a particular disease, the offspring will also have the gene that causes that disease. Organisms produced sexually may or may not inherit the disease gene because they receive a mix of their parents' genes. 
Story: Students studied two groups of organisms. Group A composed of organisms that reproduce sexually, and group B composed of organisms that reproduce asexually. They were fascinated by their discoveries. 
Question: Which group of organisms doesn't have individuals that are an exact copy of the parent?
Output (English): Group A.
