below and on your knowledge of social studies.
… europe’s waterways were also a blessing. its
rivers flowed gently into sheltered, navigable
bays. the rhine is a wide, slow-moving river that
can be used as a highway for goods and people.
the mediterranean is calm, almost a lake, with
many big ports. compare this to africa. despite
being the second-largest continent, africa has the
shortest coastline, much of which is too shallow to
build major ports. most of its big rivers—fastmoving, dramatic, vertiginous [dizzying]—are not
navigable. add to that the tropical heat and
propensity [tendency] for disease and food
spoilage, and you have a compelling geographic
explanation for african underdevelopment—
surely not the only factor, but a significant
one.…
