Question

dr. maria espinoza, a biologist, is carrying out research in the tropical rain forest of brazil. we would expect dr. espinoza to be
a studying the traditional practices of the tribes inhabiting the region.
b comparing the language of the native tribes with those of other places.
c keeping an eye out for poachers who have been illegally killing animals.
d collecting data on the biodiversity of the region for a television program.

Explanation:

As a biologist, Dr. Maria Espinoza's research in the tropical rain forest of Brazil would likely involve biological aspects. Collecting data on biodiversity (which is a biological concept related to the variety of life forms in an area) is a task that aligns with a biologist's work. Studying traditional practices (more anthropological/sociological), comparing languages (linguistics/anthropological), and keeping an eye out for poachers (more of a conservation - enforcement or wildlife management, not the core of a biologist's research as presented in the context of a biologist's research) are less likely to be the main focus of a biologist's research as described.

Answer:

D. collecting data on the biodiversity of the region for a television program.
