Question

what newer method did researchers use to study giraffe species, according to the section? a an extensive analysis of data on giraffes’ genes. b observing giraffes’ behavior in the wild. c scrutinizing giraffes’ spots. d measuring the height of giraffes’ horns.

Explanation:

To determine the newer method to study giraffe species, we analyze each option. Option A involves gene data analysis, which is a modern, molecular - based approach. Options B (wild behavior observation), C (scrutinizing spots), and D (measuring horn height) are more traditional or less “newer” methods compared to genetic analysis. So the most probable newer method is an extensive analysis of giraffes’ gene data.

Answer:

A. An extensive analysis of data on giraffes’ genes.
