1. Use of modal verbs and infinitives: "I can store hundreds of books," "it’s really easy to search for information or adjust the font size"—these show the ability to use modal verbs ("can") and infinitive structures ("to search," "to adjust") to express ability and purpose.
2. Use of conjunctions: The answer uses "and" and "or" to connect multiple ideas smoothly, which helps to organize the response clearly and logically.
3. Use of comparative and descriptive adjectives: "cheaper," "instantly available," and "really easy" demonstrate the use of comparative and descriptive adjectives to add detail and comparison.
