Question

in many rural communities, traditional healers play a crucial role in healthcare, often using herbal remedies passed down through generations, and have at times been the only accessible medical resource for people living in such areas. though the increasing availability of modern medicine has led to a decline in reliance on these healers, their roles are not ______ since remote areas have not been able to enjoy the robust medical infrastructure available in urban communities.

which choice completes the text with the most logical and precise word or phrase?
a unwanted
b negligible
c impossible
d required

Explanation:

The text states traditional healers remain crucial in remote areas lacking robust modern medical infrastructure, so their roles are not unimportant. "Negligible" means insignificant, which fits the contrast: while reliance has declined, their roles are still meaningful and not negligible. The other options do not align with the logical context: "unwanted" contradicts their crucial role, "impossible" is irrelevant to the role's existence, and "required" does not fit the contrast of declining but still present importance.

Answer:

B. negligible
