Which best describes how a Web portal can individualize user information?

1. A website that requests the user to register and then sign in each time upon entering
2. A website that provides a home page with general information about the organization
3. A website that uses the HyperText Markup Language (HTML) to display its pages
4. A website that offers specialized search engines for searching out information

1 -- Rationale: A Web portal requires users to register, thus obtaining information from the user that allows the site to personalize information for that user. It also assists the user in obtaining individualized, personalized information. Web portals use many markup languages, and provide the user with the ability to search and retrieve information (as do other websites).
