Question

Paragraph A :

The brain changes when people learn. Practice helps information
stick. Learning takes time.

Paragraph B :

Scientists have discovered that the brain physically changes when
people learn. Repeated practice strengthens connections between
neurons, allowing information to move faster and more efficiently.
Over time, these strengthened pathways help learners retain new
skills and knowledge.

Answer:

Which paragraph teaches you more and why

Answer 1

Paragraph B teaches more. It gives concrete detail about how learning happens (the brain physically changes; repeated practice strengthens connections between neurons), explains the mechanism (faster, more efficient information flow), and describes the outcome (strengthened pathways aid retention). Paragraph A states the same basic points but is very terse and lacks explanation or causal links. (A short caveat: A might be fine for a very young audience who just needs the simple facts.)
