Scientists used artificial intelligence (AI) to uncover distinct patterns of brain organization in men and women. The study around 1,500 brains and trained an AI model to predict the sex of the brain owner 90% accuracy. The researchers focused on three brain networks that are involved in self-referential processing, reward response, and emotion regulation. They found that these networks showed consistent sex differences in their connectivity and activity. The study’s lead author, Vinod Menon, PhD, said that sex plays a crucial role in human brain development, aging, and the manifestation of psychiatric and neurological disorders. He added that identifying sex differences in the healthy adult brain is a critical toward understanding sex-specific vulnerabilities in these conditions. The study some recent claims that there are no biological differences between men and women, especially in the context of transgender issues. However, some critics have whether the observed differences are due to biological or social factors, or a combination of both.

Result:

A.I. Explanation:

Correct answer: scanned
Explanation: The verb 'scanned' is the correct choice as it indicates the action of examining or analyzing the brains, which fits grammatically in the past tense and contextually with the study's methodology. The other options do not convey the same meaning of examination.
Meaning: 'Scanned' means to examine closely or analyze, particularly in a systematic way, which is appropriate for the context of studying brains.
Wrong options:
consulted: 'Consulted' implies seeking advice or information, which does not fit the context of examining brains directly.
polished: 'Polished' means to make something smooth or shiny, which is irrelevant to the context of brain analysis.
wrapped: 'Wrapped' suggests enclosing something, which does not relate to the action of studying or analyzing brains.
Correct answer: with
Explanation: The preposition 'with' is appropriate here as it indicates the manner in which the AI model predicts the sex of the brain owner, aligning grammatically and contextually with the sentence structure.
Meaning: 'With' indicates the means or method used to achieve something, in this case, the accuracy of the AI model's predictions.
Wrong options:
lacking: 'Lacking' suggests absence, which does not fit the context of achieving accuracy in predictions.
concerning: 'Concerning' implies a relation to a topic, but does not grammatically fit the structure needed here.
into: 'Into' suggests movement or transformation, which does not apply to the context of prediction accuracy.
Correct answer: step
Explanation: The noun 'step' is the correct choice as it signifies a stage in a process, which fits grammatically and contextually with the idea of progressing toward understanding vulnerabilities in brain conditions.
Meaning: 'Step' refers to a stage or action taken in a process, indicating progress toward a goal.
Wrong options:
scale: 'Scale' refers to size or extent, which does not fit the context of a process toward understanding.
race: 'Race' pertains to a classification of people, which is irrelevant in this context.
retail: 'Retail' relates to selling goods, which does not connect to the scientific context of the study.
Correct answer: contradicts
Explanation: The verb 'contradicts' is suitable as it indicates that the study opposes or challenges previous claims, fitting grammatically and contextually within the sentence.
Meaning: 'Contradicts' means to assert the opposite of a statement, indicating that the study challenges existing beliefs about biological differences.
Wrong options:
degrades: 'Degrades' implies a decline in quality, which does not fit the context of challenging claims.
constitutes: 'Constitutes' means to make up or form something, which does not align with the action of opposing claims.
echoes: 'Echoes' suggests repetition or agreement, which is contrary to the meaning of challenging or opposing.
Correct answer: questioned
Explanation: The verb 'questioned' is the correct choice as it indicates skepticism or inquiry regarding the observed differences, fitting grammatically and contextually with the sentence.
Meaning: 'Questioned' means to express doubt or seek clarification about something, which is appropriate in the context of scientific debate.
Wrong options:
programmed: 'Programmed' refers to setting a procedure or plan, which does not fit the context of inquiry or skepticism.
offended: 'Offended' implies a feeling of hurt or insult, which is not relevant to the context of questioning scientific findings.
catered: 'Catered' means to provide for needs or desires, which does not relate to the act of questioning differences.
