Questions 1–7 match ideas to named researchers. Track each person separately: Broca is linked to speech loss, Brinkman to brain function and recovery, and Geschwind and Galaburda to development before birth.
Questions 8–10 use the family table: 15–20%, 40% and 6%. Keep each percentage attached to its parental combination.
Questions 11–12 require the conclusions rather than isolated details. Check the evidence from the monkey study and the writer’s assessment of left-handed people.
