neuroscientist eleanor maguire wanted to study whether the structure of the human brain can change in response to specific life experiences, such as navigating complex environments. to test this, she used mri scans to compare the brains of licensed london taxi drivers, who undergo years of training to memorize thousands of streets and landmarks, with those of non - taxi drivers. her results showed that the taxi drivers had larger posterior hippocampi, a brain region thats important for spatial navigation. she also found that the size of this region increased with years of driving experience. maguires findings suggest that ______ which choice most logically completes the text? choose 1 answer: a mri scans are not a reliable way to evaluate brain structures in humans. b a persons navigational ability is determined by their brain structure at birth rather than their experience navigating complex environments. c the human brain can adapt its structure in response to specific life experiences. d taxi drivers naturally have larger posterior hippocampi than non - taxi drivers.

Answer

Brief Explanations:

The text starts by stating the study's aim: whether the human brain's structure can change due to specific life experiences (like navigating complex environments). The experiment compared London taxi drivers (who have years of training/memorizing streets) with non - taxi drivers. Results showed taxi drivers had larger posterior hippocampi (a region for spatial navigation) and the size increased with driving experience.

  • Option A: The text uses MRI scans as a tool for the study and there is no indication that MRI scans are unreliable. So, this option is incorrect.
  • Option B: The study shows that experience (driving years) is related to the size of the brain region (posterior hippocampi), which is against what this option claims. So, this option is incorrect.
  • Option C: Since the taxi drivers' brain region (posterior hippocampi) size changes with their experience (driving years), it supports the idea that the human brain can adapt its structure in response to specific life experiences. This option is correct.
  • Option D: The study shows that the size of the posterior hippocampi increased with driving experience, not that taxi drivers naturally have larger ones. So, this option is incorrect.

Answer:

C. the human brain can adapt its structure in response to specific life experiences.
