During the lifetime of the human body, the human brain will constantly "optimize the reorganization" of brain neural connections and "trim" excess connections to ensure that useful connections are faster and smoother. Researchers selected 121 healthy people aged 4-20 Volunteers, using bump resonance technology, analyzed the changes in neural connections at this age as the brain develops and matures. It was found that the time when women begin to "trim" brain neural connections is generally earlier than that of men. Therefore, the researchers believe that Female brains are more efficient than male brains. If the following statement is true, which one does not support the above conclusion? ['School-age girls often show better understanding and language skills than boys of the same age.', 'Errors in "trimming" brain neural connections can lead to autism, with significant gender differences in prevalence.', 'When a boy can only focus on one job, a girl can handle multiple jobs at the same time.', 'After "trimming" and "reorganizing" the brain, the efficiency of various cognitive activities is greatly improved.']
