Question

Which of the following best summarizes the section, “Road Map”? A Scientists used to rely on a map that was based on the brain of just one woman, even though there is no way one woman could represent everyone on the planet. B The old map of the brain was that of just one person, but the new, 3-D model is based on data from thousands of brains and will help doctors better understand the brain. C Researchers will be able to interact online with the 3-D model, comparing and contrasting all sorts of information about the human brain. D Doctors still do not know why brain disorders like Alzheimer's disease affect some people but not others.

Answer 1

Option B accurately summarizes the 'Road Map' section by describing the evolution from an outdated brain map based on a single individual to a modern 3-D model derived from thousands of brains, which aids medical professionals in understanding the brain better.

Step-by-step explanation:

The best summary for the section 'Road Map' is option B: "The old map of the brain was that of just one person, but the new, 3-D model is based on data from thousands of brains and will help doctors better understand the brain." This is because it encompasses the historical context of brain mapping that primarily used a singular individual's brain for reference, and it contrasts it with the advancements made possible through the aggregation of data from thousands of brains into a new three-dimensional model. This progression supports modern medical research and diagnostics by providing a more representative and detailed view of the brain's anatomy and functionality.
