Answer:
1. Authority
2. Extras
3. Order
Step-by-step explanation:
It can be harder to judge the quality of online information, especially if the publisher's or author's identity is unclear. Remember, digital texts may have been subject to less editing, checking and reviewing than those in print. Many of them, though, can actually be more accurate, since they're much easier to correct and keep up to date.
Printed texts may be accompanied by illustrations, photographs and diagrams, while digital texts can use many more "added extras," including audio and video elements, quizzes, and links to other texts. These additions can enrich the reading process, but can also become distracting, or increase cognitive load.
Most printed texts are designed to be read sequentially. With digital texts, you can navigate as you like, making it easier to find what you need. However, there's also more risk of missing something important, or of getting sidetracked by irrelevant material.
