Answer 1

The correct option that restates the main idea of the passage regarding the role of genetics in handedness is that most scientists believe handedness is genetic.

Step-by-step explanation:

The main idea of the passage revolves around the significance of handedness and its relationship to cognitive development and genetic inheritance. Regarding the options provided, the best choice that restates the main idea of the passage is (a) Most scientists believe that handedness is genetic. This statement sums up the overall connection between handedness and genetic factors discussed in the passage. Although not stated explicitly in the passages given, this option infers that since handedness can be observed early in human fossils and shows a particular prevalence (right-handedness), and because genetics play a crucial role in the transmission of traits, it is most closely aligned with the information presented.
