Task: Story Composition
Input (English): Background Paragraph: In exercises such as weight lifting, skeletal muscle contracts against a resisting force (see Figure below ). Using skeletal muscle in this way increases its size and strength. In exercises such as running, the cardiac muscle contracts faster and the heart pumps more blood. Using cardiac muscle in this way increases its strength and efficiency. Continued exercise is necessary to maintain bigger, stronger muscles. If you don’t use a muscle, it will get smaller and weaker—so use it or lose it.
Output (English): Usain was once a competitive swimmer, but he became bored with the sport and decided to start running very frequently instead. Usain tried to convince his brother, Asafa, to take up running as well. Asafa didn't really like running, though, so he hardly ran much at all.
