The answer to the first unknown is "FRATERNAL TWINS" while in the second unknown is "SISTERS". Hence, we have it, Mia and Thalia are very similar to each other especially with respect to their appearances and to each other in the personality trait of openness. While Esther and Hannah are less similar to one another in openness. We can say that Mia and Thalia could be FRATERNAL TWINS, whereas Esther and Hannah could be SISTERS.
Scientists should definitely use evidence - and they collect this evidence though especially designed experiments. Based on their data and assumptions they build models which they then test, but they can base their conclusions based on the models too.
What they should not do is based the conclusions on opinions, because opinions are not imparcial- they can state them as opinions, but not as conclusions.

This scenario is one of :
B. Kin selection.
Explanation:
In Evolutionary Psychology, the concept of Kin selection is an important one in terms of Darwinism study and the study of shared genetics.
It basically means that the people of the same kin are predisposed to each other by their genetics that are common.
This would mean that there is a higher chance of successful organ donation inside the kin than outside because the bodies of the people are familiar in terms of their genetic make up.
