Question

which of the following statements is true?
a. a hypothesis is supported by predictions, not tests.
b. a theory is supported by many experiments.
c. a hypothesis is considered false until proven true.
d. a theory is so strong that it can never be changed.

Explanation:

• A hypothesis is tested through experiments, not just supported by predictions (so A is wrong).
• A hypothesis is an educated guess and is neither assumed true nor false initially; it is tested (so C is wrong).
• Theories can be modified or updated based on new evidence (so D is wrong).
• A theory is a well - established explanation that is supported by a large body of experimental evidence.

Answer:

B. A theory is supported by many experiments.
