b. Predicting your horoscope
Explanation:
Pseudoscience refers to claims that are scientifically misleading and do not follow the scientific method. For example, imagine someone claims a certain drug will make you live forever. This is an example of pseudoscience. It has not been tested using the scientific method and it is misleading.
The scientific method follows this general structure.
1. Ask a question
2. Do background research
3. Construct a hypothesis
4. Test your hypothesis
5. Analyze data and draw a conclusion
6. Communicate your results. (Was your hypothesis correct?)
Finding a new star, dating the age of a fossil, and finding new uses for a drug all are processes that use the scientific method. Predicting your horoscope is not a science and it has not been proven using the scientific method.
