Question

The statement to evaluate is: 'Professor Cingel notes that over the first two years of life the human brain triples in size.'
Option A: True. This option asserts that the brain increases threefold in the first two years. In developmental neuroscience, the human brain does undergo rapid growth after birth, with substantial increases in size and weight during infancy, but typical estimates describe the brain reaching about 60-80% of its adult weight by age 2, not a full threefold increase from birth. This means a literal tripling in size is not supported by standard neurodevelopmental data.
Option B: False. This alternative claims that the statement is not accurate. Most reliable sources indicate that the brain grows rapidly in the first years of life, particularly in early infancy, with major synaptogenesis and myelination processes, and while it does gain a large fraction of adult size by age 2, it does not typically triple its size from birth. Therefore, describing a threefold increase would overstate the typical growth trajectory described in mainstream developmental neuroscience, making this option align more closely with established findings.
Option C (if considered): Some texts discuss that from birth to around age 2, the brain's mass increases substantially, but clinicians and researchers often cite that by age 2 the brain is roughly 75% of adult weight, not three times birth size. This nuance matters for precise interpretation, and could influence whether one labels the claim as accurate.
Option D (if considered): Another angle is that growth rates differ across brain regions; while overall volume increases dramatically, the exact multiplier can vary by methodology and measurement (weight vs. volume, gray vs. white matter). This variability can lead to different quoted figures, but the core assertion of a strict tripling remains inconsistent with common growth benchmarks.
In sum, evaluating the specific claim against typical developmental data suggests that the most defensible interpretation is that the statement is not accurate in the sense used by standard neuroscience references, given the conventional milestone that brain weight by age 2 is substantial but does not equal a threefold increase from birth.
