The use of an abacus to solve a mathematical equation is useful in helping the brain form a mental picture of the problem.
D.
Using cultural tools frequently causes connections in the brain’s nerve endings to strengthen.

Answer 1

C

Explanation: The abacus is a clear example of a cultural/historical tool that mediates cognitive activity—using it helps learners externalize and then internalize strategies for calculation (Vygotsky’s "tools of intellectual adaptation"). The other options are either general perceptual tasks (B), a vague/less accurate description of symbolic language use (A), or a neurobiological claim about synapses rather than an example of cultural mediation (D).
