What is the primary focus of structural analysis in reading?

The primary focus of structural analysis in reading is indeed related to examining the graphic features of words, such as prefixes and suffixes. This approach involves breaking down words into their constituent parts to understand their meanings and to help readers recognize and decode unfamiliar words. By analyzing the structure of words, readers can make educated guesses about the meanings of new vocabulary, enhancing their overall comprehension and fluency in reading. Understanding these word parts is crucial for building vocabulary and improving reading skills, especially for elementary students who are still mastering the basics of language.

The other choices, while important reading strategies, do not directly align with the concept of structural analysis. Identifying the main idea, summarizing content, and determining the author's purpose involve different aspects of comprehension and interpretation rather than the specific breakdown and analysis of word structure.
