True is the correct answer for the above question.
Explanation:
The subject directory is a concept that is used to view the content of any relevant subject in the form of the tree structure. For example, if there is a subject science. So when the user clicks on the science it will get three links physics, chemistry, and biology. when the user clicks on the future, he will get a further link so on. And in the last, the user will get the content related to the topic.
This type of directory is also created by humans, not by any AI methodologies. This helps users to get aware of some topics. Any user can go on any particular content after clicking many levels which are defined in the example above.
The above question statement also states the same, hence it is a true statement.
