Four groups of students, in different parts of the world, are investigating the reason why the shape of the moon changes from time to time. If the results of their investigations are considered valid, they would most likely be (2 points) complex
identical
non-testable
inconsistent

Identical because the moon changes it’s look everyday but in the same order every month so if they kept keeping data then they would have a consistent pattern and what they’re doing right now is testing how the moon looks different so it wouldn’t be “non-testable” and it probably wouldn’t be complex because it’s pretty easy to keep data and draw and describe the moon every night so no hard work needed. that’s why i think the right answer is “identical”

Ca mega city if i’m not mistaken
