Final answer:
Brian should use quotation marks around the phrase "business strategies that were adopted by top CEOs" in his online search to get results for the exact phrase.
Step-by-step explanation:
Brian intends to use the phrase 'business strategies that were adopted by top CEOs' in his online search. To ensure that the search engine looks for the phrase exactly as it is, Brian should place quotation marks around the entire phrase when he inputs it into the search engine.
This would look like "business strategies that were adopted by top CEOs". The use of quotation marks tells the search engine to search for the exact phrase, maintaining the order and composition of the words within the quotes.
Without quotation marks, the search engine may interpret the search as needing to find pages where the words business, strategies, that, were, adopted, by, top, CEOs appear in any order and any part of the page, which could lead to less relevant results.
