Final answer:
The left hemisphere is responsible for language processing in about 95% of individuals, and it specifically carries out this function, unlike spatial awareness, facial recognition, or emotional expression which involve both hemispheres.
Step-by-step explanation:
In most individuals, the specific function of the left hemisphere that is typically not controlled by the right hemisphere is A) Language processing. The left hemisphere of the brain is predominantly responsible for language functions in about 95 percent of the population. This lateralization of brain function means that, even though the hemispheres are connected by the corpus callosum and can share information, language processing is mainly localized to the left hemisphere, which then communicates with the right side of the body through neural pathways such as the corticospinal tract. Other functions such as spatial awareness (B), facial recognition (C), and emotional expression (D) are not exclusively under the control of the left hemisphere; they involve both hemispheres, with each having different specializations.
