Answer:
1. "He took a four-mile, 25-minute ride with his friends that left him severely distressed." --> description
2. "But his symptoms worsened overnight, and his heart was still racing at 130 beats per minute when Krauss saw him two months later." --> fact
3. "The doctor's diagnosis was short and to the point: ‘over-cycling.’ --> expert's testimony
Explanation:
There are several types of evidence that can be used in writing or speaking. Different types of evidence have different influential powers according to the context in which they are used as well as their purpose.
Evidence number 1 is a description: it offers information as to what happened; how and when the problem being addressed started. Evidence number 2 is a fact: an occurrence verifiable through observation or research. In this case, it is the heartbeat rate that is easily verifiable. Finally, evidence number 3 is an expert's testimony: a reliable opinion given by someone who has expertise in a certain area. The doctor, who is a specialist in health, came to the conclusion that over-cycling was the cause of the issues.
