Question

read the text.
among american robins, the female does most of the nest - building. she starts by selecting a good site. usually, this is a place protected from rain, wind, and sun, often on tree branches hidden by leaves. then, using grasses and small twigs, she forms a cup - shaped nest. after forming this cup, the robin adds mud to reinforce it and cement it to its location on the tree branch or other base. finally, she lines the nest with soft grasses and hairs. all this usually takes about five or six days, and it results in a fine home, about six to eight inches across and three to six inches high.
which organizational structure does this text primarily use?
cause - effect
sequential
compare - contrast

Explanation:

The text describes the nest - building process of American Robins in a step - by - step manner. It starts with selecting a site, then forming a cup - shaped nest, adding mud, and finally lining the nest. This is characteristic of a sequential structure where events or actions are presented in the order they occur. In a cause - effect structure, there would be a focus on why something happens (cause) and what happens as a result (effect). In a compare - contrast structure, there would be a focus on similarities and differences between two or more things. Since the text is about a process in order, it is sequential.

Answer:

sequential
