A colon is used to explain a enumeration. A enumeration is a complete, ordering listing of all the items in a collection. I searched it up give the credit to Google.
The correct answer is "In this selection, the use of the word <em>inundation</em> is probably exaggerated."
In this situation, inundation is not a real inundation/flood, therefore it is not literal. It is a word used to exaggerate the fact that the housewives are constantly cleaning the house, sweeping and mopping. You can see that too in the excerpt <em>"under the discipline of mops and brooms". </em>We know the author is referring to the cleaning process and therefore, chooses to use the word <em>inundation</em> to create more depth to what he's describing.
Answer:
Social media is a good way to stay in touch with friends and family who live far away. But if we focus more on the people online than those who are nearby physically, or if we allow our friends who are in close proximity to become online friends only, then we have a problem. We can maintain those online friendships, but we should never substitute them for real friendships with people with whom we can talk and do things in person. Some in-person relationships may be difficult.
