77. A third-grade teacher displays a passage about giraffes on a whiteboard. The passage on giraffes is best for teaching students about which of the following informational text structures?
Answer: B
The passage on giraffes is best for teaching students about the descriptive informational text structure.
Descriptive text structures are used to provide detailed information about a subject, often including characteristics, features, and examples. The passage about giraffes likely contains vivid descriptions that help students visualize and understand the unique traits of these animals.
A) Problem and solution
The problem and solution structure focuses on identifying a problem and proposing one or more solutions. Since the giraffe passage does not center around a specific issue or resolution, this option is not applicable.
B) Descriptive
The descriptive structure is characterized by providing detailed information about a subject, which is precisely what a passage about giraffes would do. It likely includes descriptions of their physical attributes, habitat, and behaviors, making this the most suitable option for teaching this text structure.
C) Cause and effect
The cause and effect structure illustrates how one event leads to another. A passage about giraffes does not typically discuss events in terms of causes and their subsequent effects, thus making this option incorrect.
D) Persuasive
Persuasive texts aim to convince the reader of a particular viewpoint or action. A passage focused on giraffes is unlikely to be written with the intent to persuade, as it would primarily present factual information rather than arguments or opinions, rendering this option incorrect.
Conclusion
The descriptive structure is the most appropriate choice because it aligns with the intent of providing detailed information about giraffes. All other options are not relevant to the nature of the passage, as they focus on different text structures that do not apply to the characteristics and traits of giraffes being described.
