Question

hypothesis, theories, and laws
in science, scientific _____, hypotheses, _____, and laws each have a very different meaning.
hypothesis and theories
observations and facts
lead to
hypothesis
incorporated into
theory

Explanation:

The sentence is about scientific concepts. In science, the terms "facts", "hypotheses", "theories", and "laws" are key. The first blank should be "facts" (since observations and facts lead to hypothesis, as per the diagram: Observations and Facts lead to Hypothesis, then Hypothesis incorporated into Theory). Then the next blanks: after "scientific", the first term is "facts", then "hypotheses", then "theories", then "laws" (to match the title and the scientific process: facts are the basis, then hypotheses are proposed, then theories are developed, and laws are descriptive of natural phenomena). So filling the blanks: In science, scientific \underline{facts}, hypotheses, \underline{theories}, and laws each have a very different meaning. (The diagram shows Observations and Facts lead to Hypothesis, then Hypothesis incorporated into Theory, so the order in the sentence should follow the scientific concepts: facts, hypotheses, theories, laws.)

Answer:

In science, scientific \underline{facts}, hypotheses, \underline{theories}, and laws each have a very different meaning.
