After giving students the meanings of the words automobile and autopilot
A. a teacher asks students to guess the meaning of the word autobiography. Which of the following best identifies the objective of the lesson?
B. Memorizing common suffixes
C. Breaking down base words into parts Correct
D. Applying knowledge of prefixes
E. Accessing high-frequency sight words
Rationale: The objective of the lesson focuses on understanding how words can be broken down into their components. Option C, "Breaking down base words into parts," directly relates to analyzing the root "auto" in both "automobile" and "autopilot," helping students infer the meaning of "autobiography."
Option A lacks clarity as it does not specify a learning strategy. Option B, "Memorizing common suffixes," is too narrow, as the lesson emphasizes understanding rather than rote memorization. Option D, "Applying knowledge of prefixes," is also incorrect since the focus is on the root rather than prefixes. Lastly, Option E, "Accessing high-frequency sight words," is unrelated to the lesson's aim of word analysis.
