insect vectors that carry chagas disease often reside in homes made of adobe, mud, straw, and other materials.	○	○	○
experts believe that close to fourteen percent of americans have been exposed to the parasite that causes toxocariasis.	○	○	○

Explanation:

1. For "While tens of millions of Americans carry the toxoplasmosis parasite, not all show symptoms": This is about how common the parasite is (prevalence), so it fits Prevalence.
2. For "Those who contract trichomoniasis can usually rid themselves of the parasite with a single course of antibiotics": This is about how to treat the infection, so it fits Treatment.
3. For "Insect vectors that carry Chagas disease often reside in homes made of adobe, mud, straw, and other materials": This is about how the disease is transmitted (via insect vectors and their habitat), so it fits Transmission.
4. For "Experts believe that close to fourteen percent of Americans have been exposed to the parasite that causes toxocariasis": This is about the prevalence (how many are exposed), so it fits Prevalence.

Answer:

1. "While tens of millions of Americans carry the toxoplasmosis parasite, not all show symptoms" → Prevalence
2. "Those who contract trichomoniasis can usually rid themselves of the parasite with a single course of antibiotics" → Treatment
3. "Insect vectors that carry Chagas disease often reside in homes made of adobe, mud, straw, and other materials" → Transmission
4. "Experts believe that close to fourteen percent of Americans have been exposed to the parasite that causes toxocariasis" → Prevalence
