Final answer:
The task involved classifying sources of information into their respective categories of print, online, or broadcast after eliminating the item that did not belong in each group, while understanding the importance of proper research methodologies.
Step-by-step explanation:
Identifying sources of information and determining their appropriate categories is an important skill for conducting academic research. After examining the groups of sources presented and removing the one that does not belong, we're able to categorize the remaining into mediums such as print, online, or broadcast. Here are the categories with the non-belonging sources removed:
- Group 1 (broadcast): Textbooks, workbooks, reference books - remove 'daily TV news'
- Group 2 (print): TV documentaries, radio comedies, TV commercials - remove 'e-book'
- Group 3 (online): Blogs/vlogs, videos, webpages - remove 'written diary'
- Group 4 (print): Printed magazines, printed newspapers, printed journals - remove 'social media'
- Group 5 (online): Email, e-book, mobile app - remove 'book'
These categorizations relate to the mediums through which the information is disseminated. Understanding the right research process and where to look for existing sources can aid in distinguishing between various types of sources such as primary, secondary, and tertiary, and determining their credibility.
