Correct Option: E

AI Explanation

To answer this question, you need to understand how case sensitivity works in search queries.

Option A) new york city - This option is incorrect because it is in lowercase. Search engines generally treat uppercase and lowercase letters differently, so this query may not produce accurate results.

Option B) New York city - This option is incorrect because it only capitalizes the first letter of each word. While this may improve the accuracy of the search results compared to option A, it is not the ideal format.

Option C) New York City - This option is incorrect because it capitalizes the first letter of each word, which is a common convention for proper nouns. However, search engines do not necessarily consider capitalization rules when processing search queries.

Option D) NEW YORK CITY - This option is incorrect because it uses all uppercase letters. Similar to option A, search engines may not interpret uppercase and lowercase letters the same way, so the results may not be accurate.

Option E) It doesn't matter, only special query keywords are case sensitive. - This option is correct because it acknowledges that only special query keywords are case sensitive. In general, search engines do not differentiate between uppercase and lowercase letters in regular search queries. Therefore, the case sensitivity of the query does not significantly impact the search results.

The correct answer is E. It doesn't matter, only special query keywords are case sensitive. This option is correct because uppercase and lowercase letters do not significantly affect the results of regular search queries.
