How do the two sentences relate?

Question

Combining insecticide-treated bed nets with vaccines and other control measures may provide the best chance at eliminating malaria.
More than 20 malaria vaccine candidates are in different stages of development, but none are licensed for use.

Answer 1

Hi Sylvia,

 

Both sentences deal with fighting malaria.  The 1st offers a suggestion about how to eliminate malaria.  The 2nd provides information that questions the feasibility of that suggestion.

 

I hope that helps.
