Passage-based question 2

Problem

These five questions all refer to the information below. The information is the same for each question.
A company develops a social media application that allows users to make public posts. However, soon after launching, the company observes a proliferation of posts containing hate speech (abusive writing that's prejudiced against a group of people) and fake news (deliberately false information).
To address the issue, the engineers develop a moderation algorithm and use it to decide whether a post should be hidden or marked with a warning.
The original posting system and new posting system are described in the following flowcharts. Each flowchart uses the following blocks:
BlockExplanation
OvalThe start of the algorithm
ParallelogramAn input or output step
DiamondA conditional or decision step, where execution proceeds to the side labeled "Yes" if the answer to the question is yes and to the side labeled "No" if the answer is no
RectangleThe result of the algorithm
A flow chart of the original posting system:
  • An oval is labeled "Start" and points to a parallelogram.
  • That parallelogram is labeled "User logs into application" and points to another parallelogram.
  • That parallelogram is labeled "User writes and submits post" and points to a rectangle.
  • That rectangle is labeled "Post is published".
A flow chart of the moderated posting system:
  • An oval labeled "Start" points at a parallelogram.
  • That parallelogram is labeled "User logs into application" and points to another parallelogram.
  • That parallelogram is labeled "User writes and submits post" and points to a diamond.
  • That diamond is labeled "Does the post contain hate speech?" with two arrows labeled "Yes" and "No".
  • The "Yes" arrow points to a rectangle that's labeled "Post is hidden".
  • The "No" arrow points to a diamond that's labeled "Does the post contain fake news?" with two arrow labeled "Yes" and "No".
  • The "Yes" arrow points to a rectangle that's labeled "Post is marked with warning".
  • The "No" arrow points to a rectangle that's labeled "Post is published".
Which of the following data is not provided directly from the user but is necessary for the moderation system to operate as described?
