Question

Haiti faced all of the following problems, except

a. lack of roads.
c. poverty.
b. overabundance of foreign investment.
d. rising crime.

Answer 1

B (but why are they out of order?)
"overabundance" means "too much" or "more than necessary"
Haiti does NOT have too much foreign investment : the opposite is true,
in that Haiti has trouble attracting foreign companies and investments,
for several reasons.

Answer 2

Haiti faced all of the following problems, except an "b. overabundance of foreign investment," since a great deal of foreign investment would have helped Haiti improve its infrastructure and many other things.
