The evidence that is most useful when making predictions depends on the context and the type of prediction being made. However, in general, the most useful evidence is empirical evidence that is based on observations, experiments, or data. This type of evidence is objective, verifiable, and can be used to test and refine predictions.
For example, when predicting the outcome of an election, the most useful evidence would be polling data that is based on a representative sample of the population. This data can be used to make statistical predictions about the likely outcome of the election, and can be updated as new data becomes available.
Regarding the second question, the correct answer is:
Muscles in the small intestine are smooth and involuntary. They are responsible for the contraction and relaxation of the small intestine during digestion, which helps to move food through the digestive system. The smooth muscle tissue in the small intestine is different from striated muscle tissue, which is found in skeletal muscles and is under voluntary control, and cardiac muscle tissue, which is found in the heart and is also involuntary.
