Question

value: 2
a scientific investigation generally begins with ______, followed by the formation of a hypothesis to answer the question.
○ a. observations that lead to a question
○ b. questions that lead to an observation
○ c. a theory that leads to an observation
○ d. all of the above
○ e. only a and b
○ f. only b and c
○ g. only c and a

Explanation:

In a scientific investigation, the process typically starts with making observations. These observations then prompt a question. A hypothesis is formulated to answer that question. Option b is incorrect because it's observations that lead to a question, not the other way around. A theory is a well - established explanation that comes after multiple steps of investigation, not at the beginning, so option c is wrong. Since b and c are incorrect, options d, e, f, g are also incorrect.

Answer:

A. observations that lead to a question
