D. Singer, Ming. Preventing Heart Disease. Boston, MA: McMaster Brothers, 2013. Print.

Out of these options, the one that seems most credible is the last one. The first option was published by "Candy Makers of America Press" in praise of high-fructose corn syrup, which is universally accepted to be bad for health. The second option was self-published, which means that it was not peer-reviewed and it is more likely to have errors. The third option discusses ways to improve your health, not threats to your health. However, the fourth option discusses a threat to health as well as being published by a credible source.

the correct answers are:

c. “never in the history of his people had a man married a woman who spoke a different tongue.”

d. “‘it has never been heard,’ was the verdict of an old man speaking a few weeks later.”

e. “this man had come with others to commiserate with okeke.”
