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
A) complex
B) identical
C) non-testable
D) inconsistent
is it b
Yes, B.
To determine the answer to this question, let's analyze the given information.
The question states that four different groups of students, located in different parts of the world, are investigating the reason why the shape of the moon changes.
If the results of their investigations are considered valid, it means that each group has conducted thorough and reliable research.
Given that the groups are located in different parts of the world, it is highly unlikely that they have collaborated or that their investigations are identical. This means that the answer cannot be B) identical.
Complexity refers to the level of intricacy or difficulty involved in a task or situation. With regards to the investigation of the changing shape of the moon, it is indeed a complex topic that requires scientific knowledge and rigorous research. Therefore, option A) complex is a possible answer.
Non-testable refers to situations or research questions that cannot be scientifically tested or verified. Since the question explicitly states that the groups are conducting investigations, we can assume they are performing valid tests and collecting data. Therefore, option C) non-testable is unlikely to be the answer.
Inconsistency implies a lack of reliability or coherence. Based on the information provided, we cannot conclude that the investigations conducted by the four groups are inconsistent. Hence, option D) inconsistent is not the most likely answer.
Considering this analysis, the most reasonable answer is A) complex.
