Which of the following is not a barrier to economic development?
a. foreign debt
b. political stability
c. widespread disease
d. low levels of social welfare

Political stability is not a barrier to economic development - the correct answer is b)!

In fact, political stability supports economic development, for example by removing the fear of potential investors.
All other options are a barrier, for example foreign debt means that rather than investing, a country has to pay it back.

This is what i found on google “eightin 1997, the mccaughey septuplets were born in carlisle, iowa. multiple births of as many as eight babies have been born alive, the first set on record to the chukwu family in texas in 1998; one died and seven survived. in 2009, a second set, the suleman octuplets, were born in bellflower, california.” i was surprised about this . i don’t want to have that many babies .
