Answer:
A. It is based on logical reasoning.
C. It is based on empirical evidence
Step-by-step explanation:
A scientific claim is based on logical reasoning and empirical evidence. Logical reasoning is done with the help of established theories and principles. Empirical evidence is collected from analysis of observations and experimentation results. In contrast, long tradition need not be scientific in nature. Many traditional activities are a result of word of mouth practice. Personal bias can also be not used to form a scientific claim since it is biased in one direction and can skew the judgement.
