Final answer:
The characteristic of a left-brain thinker is being analytical, as the left side of the brain is associated with tasks involving language and analytical skills.
Step-by-step explanation:
A characteristic of a left-brain thinker is being analytical. This contrasts with right-brain thinkers who are often associated with being more intuitive or creative. The left cerebral hemisphere is indeed linked to language functions and analytical tasks, while the right is tied to spatial and nonverbal reasoning. There is some lateralization of function in the brain, meaning certain cognitive processes tend to be more dominant in one hemisphere than the other; however, many cognitive functions, such as language, are used across the cerebrum, debunking the oversimplified myth of being solely "left-brained" or "right-brained." When referring to analytical intelligence, it involves examining data, observing patterns, thinking critically, and solving problems, which are predominantly left-brain activities. Therefore, the correct answer to the question is C) Analytical.
