jamal is learning more about how to tell whether a substance has undergone a physical or chemical change.
options: guessing the answer, asking questions based on scientific knowledge, asking his friends their opinions, assuming the examples are already correct.
check answer, remaining attempts: 3

Explanation:

To reason effectively about physical/chemical changes (a scientific topic), using scientific knowledge - based questions is logical. Guessing, asking friends (non - scientific opinions), or assuming examples are correct don't involve scientific reasoning. So "asking questions based on scientific knowledge" is the right choice.

Answer:

B. asking questions based on scientific knowledge (assuming the options are labeled with letters, if not, the option text is "asking questions based on scientific knowledge")
