Trevor is scratching his head, trying desperately to solve a visual analogy as part of an intelligence test; Sienna, meanwhile, is giving an oral presentation in a political science class. Of the brain's hemispheres, Trevor's hemisphere and Sienna's hemisphere are MOST active.

The answer is right and left, respectively.

Explanation:

Trevor's right hemishphere is most active, as it processes visual information and is mostly in charge of creative thinking. A visual analogy requires the use of imagination and intuition, skills dominated by the right hemisphere.

Sienna's left hemisphere is most active, as it is responsible for logical thinking, language and sequencing. An oral presentation requires linear, organised thought, an ability driven by the left hemisphere.
