Accepted Answer

Hi everyone here's the next question. It says a blank is an assumption made before any research has been done. Whereas a blank is attested. Well substantiated unifying explanation for a set of verified and proven factors. Well let's start with the first blank here. An assumption made before any research has been done. Think about the beginning of the scientific method. And we recall that you always start with a hypothesis which is that assumption that guests you have before you begin your research. Um The question you're gonna be in exploring. So hypothesis will be our first term. We see in choice B. We have that choice A. Has it in second place. So that's not correct and choice C. And choice choice C. Does not include hypothesis at all. So that's not our answer. Choice D. Has hypothesis in the second place. So that's not correct there. So we're left with only one choice hypothesis, choice B hypothesis and theory for the second space. So let's double check that um is a theory attested. Well substantiated unifying explanation for a set of verified improvement factors. That is correct. So you come up with a theory When there have been repeated experiments. Those experiments have been duplicated by other researchers. So lots of evidence. Well substantiated. Um experiments repeated by more than one person and sort of a unifying explanation of a set of verified improvement factors. So we see that in choice a theory and hypothesis that had the two correct terms but they were in the wrong order. Um And enjoy. See it used the term law and a law refers to generalize law or principle formulated to describe patterns observed. Um But again, definitely isn't the assumption made before the research has been done, and both C and D. Law is in that place where hypothesis should be. So Choice B is our correct answer. A hypothesis is an assumption made before any research has been done, whereas a theory is a tested well substantiated, unifying explanation for a set of verified and proven factors. See you in the next video.
