1647. 10,000 New York City Road Runner members were surveyed and classified based on the number of hours per week that they ran. The runners were classified as 'Running more than 10 hours per week' and 'Running less than 10 hours per week.' Runners were then followed for the next 5 years to determine which runners develop stress fractures.

Incidence rates of stress fractures per year per 1,000 runners:

Running less than 10 hours per week: 0.28

Running more than 10 hours per week: 0.63

Calculate the relative risk of developing stress fractures associated with running more than 10 hours per week.

2031. One common association that people have is called conditioned taste aversion, which occurs when you eat or drink something and then get sick. A conditioned taste aversion is most likely to occur when the food or drink is relatively unfamiliar. Suppose you have acquired a conditioned taste aversion to tequila. Identify the unconditioned stimulus, unconditioned response, conditioned stimulus, and conditioned response in this example. Next, write down an example of something you have learned recently that involves operant conditioning. Provide a clear description of the behavior that is being conditioned, describe and label the reinforcer (positive or negative) influencing the behavior, and specify the schedule of reinforcement involved in this behavior.

1st Part:

With respect to the taste aversion part of the question, it's important to clearly distinguish a) the unconditioned stimulus from the conditioned stimulus, and b) the unconditioned response from the conditioned response. Remember, the unconditioned response does not need to be the same as the conditioned response.
