How should login-gated content affect quality assessment?

• A. If essential information is behind a login, it may lower perceived usefulness; evaluate based on available content.
• B. It should be evaluated solely on the login page's availability, ignoring content quality.
• C. When information is behind a login, usefulness decreases; evaluate with accessible content.
• D. It cannot be assessed without access to the full content.

Answer: (C)

When content is behind a login, its usefulness to many users is limited, so the quality assessment should be based on what is actually accessible without credentials. This means evaluating the portion you can preview or access without signing in, and recognizing that the gated content reduces overall usefulness for the typical user. The best answer captures that idea by stating that usefulness decreases when information is behind a login and that you should evaluate using the content that is accessible. This keeps the assessment grounded in the user’s real experience and avoids overrating content you can’t view.
