Read the paragraph from a research-based informative essay on automated vacuum cleaners.
Automated vacuum cleaners are now commonly used
appliances. They cruise around living spaces, cleaning
up debris and occasionally getting stuck behind sofas.
These vacuums remove at least for the most part—the
need for a human involvement from this chore. Now
hotel chains may begin adopting these automated
vacuums to help clean guest rooms and conference
centers. In an interview, the general manager of the Star
Hotel in Oahu, Hawaii, acknowledged that, these
vacuums make the cleaning process more efficient for
my staff. If hotels are using these automated vacuum
cleaners, perhaps it won't be too long before they begin
to roam airports, restaurants, and even supermarkets.
How should the writer revise the paragraph to correctly
integrate the cited research from the interview with the
hotel manager?
O by adding source information in parentheses at the
end of the quote
O by adding quotation marks around the direct quote
from the manager
O by adding the date and time of the interview with the
manager
O by adding a summary after the hotel manager's direct
quote
