Answer:
The correct answer is the first option displaying data in a colored chart.
Step-by-step explanation:
Hello!
Let's solve this!
Let's analyze each of the options:
-displaying data in a colored chart: this option would not affect the reliability of the scientists since the colors of the table do not contribute data to the investigation.
-clearly identifying the sources of the data: this option does provide reliability since when checking the source, the scientist ensures that his research is well done.
-explaining how the data was collected: this gives reliability as it opens the doors for others to see that their research is valid.
-showing that many scientists had reviewed the information: it gives reliability since if many have verified it, research is more relevant.
After the analysis, we conclude that the correct answer is the first option displaying data in a colored chart.
