Gina and Frankie collaborated to write a wiki. Here’s an excerpt from their work: What do the diseases malaria, yellow fever, dengue fever, and encephalitis, or inflammation of the brain, have in common? They are all carried by mosquitoes. In fact, mosquitoes cause more death than any other insect. Yet a mosquito’s purpose for biting is not to pass on disease but rather to ingest, or take in, the blood protein it needs to make eggs.

What could Gina and Frankie do to make their wiki more interactive?

A.
They could post a picture of a mosquito.
B.
They could provide a link to information about malaria.
C.
They could invite readers to add their own mosquito facts.
D.
They could include a chart of the number of deaths caused by mosquito-borne diseases each year.
