The `match` method returns an array of matches found in the string. If the pattern matches multiple characters, the method will return an array with all those matches. However, if the regular expression is set to find only the first occurrence (which is the default behavior when no global flag `g` is specified), it will return only the first match it encounters.

As a result, the output of `console.log(paragraph.match(/[A-Z]/))` will be an array containing just this first matching uppercase letter.

Thus, the correct output is an array containing "T". This is
