Final answer:
A house where television is the main source of internet might feature a living room dominated by a large TV screen with minimal books, members often absorbed by the screen, and a lack of physical printed media due to reliance on digital content for information.
Step-by-step explanation:
Describing a house where the television is the main source of internet with reference to Roald Dahl's poem "Television" leads us to imagine a few key scenes. First, the living room might be centered around a large TV screen, which not only broadcasts traditional television programs but also streams digital content. There might be minimal bookshelves or books, as the poem criticizes the television for taking away from reading and children's creativity. Second, the household members, especially children, may frequently gaze at the screen, potentially at the cost of engaging in other activities, mirroring the poem's depiction of mesmerized kids. Lastly, due to the reliance on television for both entertainment and information, physical newspapers and other forms of printed media might be notably absent, as the TV and connected devices are primary sources for news and updates.
