Explanation:

Question 1

Theories are concise, can be revised, and are supported by empirical evidence. So none of the options are incorrect in a general sense. But if we assume the question is from a basic science education context where "concise" might be mis - interpreted (though it's actually a correct property), but more likely, if we consider that all theories must be supported by empirical evidence (c is true), can be revised (b is true), and are concise summaries of knowledge (a is also true). However, if we assume a trick in the question, maybe in some non - standard view, but in standard scientific terms, all these are true. But if forced to choose, perhaps the question has an error. But if we go by the strictest sense, all are true properties of theories.

A hypothesis is a proposed explanation for a phenomenon. Here, the statement about goldfish growth based on diet is a proposed relationship (if - then statement), which is characteristic of a hypothesis. A theory is a well - established explanation with extensive evidence, and a law describes a universal relationship (e.g., mathematical relationship).

A theory explains the "how" and "why" of a phenomenon. A hypothesis is a tentative proposal, and a law describes a relationship (usually in a more mathematical or general observational sense without explaining the cause).

Answer:

All options (a, b, c) are true of theories. But if we assume the question is wrong and we have to pick based on common textbook errors (though it's not correct), there is no valid 'not true' option.
