Answer:
C. an article called “What Is Diabetes?” that defines diabetes and appears on a national health organization website
Explanation:
The pharmaceutical website and medical-supply website may be biased because their goal is to sell the viewer pharmaceuticals and medicine. A news article will probably not be as educational and give as much factual evidence as a national health organization, which has likely conducted its own research.
Pneumonia - respiratory system (affects the lungs)
Endometriosis - reproductive system (affects the uterine lining)
Fibromyalgia - muscular system (affects muscles, tendons and ligaments)
Dermatitis - integumentary system (affects the skin)
If they're unlike things - it would be a metaphor.
When it comes to similes - you use words such as like or as when describing things. and since it emphasizes "unlike" things - metaphor would be the way to go.
It's quite hard sometimes when it comes for deciphering the two if you're familiar with the rule - so just remember: Simile: like or as.
Metaphor: extreme exaggeration, or a comparison without using like or as.
I hope all is well, and you pass! (: Good luck, rockstar! (:
