This question was initially incomplete. Here is the full question:
Many Web browsers allow users to open anonymous windows. During a browsing session in an anonymous window, the browser does not record a browsing history or a list of downloaded files. When the anonymous window is exited, cookies created during the session are deleted. Which of the following statements about browsing sessions in an anonymous window is true?
a) The activities of a user browsing in an anonymous window will not be visible to people who monitor the user's network, such as the system administrator.
b) Items placed in a Web store's shopping cart for future purchase during the anonymous browsing session will not be saved on the user's computer.
c) A user will not be able to log in to e-mail or social media accounts during the anonymous browsing session.
d) A user browsing in an anonymous window will be protected from viruses launched from any Web sites visited or files downloaded.
The correct answer is b) Items placed in a Web store's shopping cart for future purchase during the anonymous browsing session will not be saved on the user's computer.
Explanation:
For e-commerce sites, shopping cart information are stored as cookies on the visitor's computer such that when the website visitor leaves the website and comes back a few days later, their shopping preferences are remembered.
If the website visitor uses an anonymous window, the cookies created during the browsing session will be deleted when the anonymous website is exited and so, items placed in the shopping cart for future purchase will not be saved.
Answer:
Nothing will be printed
Explanation:
You can easily find out that FL is not a member of the Dictionary. And we are checking these in the if. Since the if condition ends up being false, the further process will not run as they will only if the condition ends up being true. Hence, nothing will be printed.
Remember, del is used to delete a dictionary item. If this would have been a true condition for if then the FL item in the dictionary would have been deleted as it, in that case, would have been present there. And then the next line would have again added the FL item, and print would have printed the dictionary items with FL item as well. However, since if the condition is ending up being false, nothing will be printed.
If cities['FL'] and print is outside if then
the output will be
{'FL': 'Tallahassee', 'GA': 'Atlanta', 'NY': 'Albany', 'CA': 'San Diego'}

Answer:
Explanation:
The basic concept of virtual reality is that they are a pair of lenses in a headset that allows you to visualize a virtual 3D world and become immersed within it. To do the exercises correctly Anna would need to follow the following basic steps.
Put the virtual glasses over her eyes, complete the exercises in the virtual world, take the virtual glasses off
The headset/glasses need to fit comfortably on her eyes and around her head so that she can clearly see the image on the lenses and so that the headset/glasses do not fall off while she is completing her exercises. Once she is done with her exercises Anna can simply take off her virtual glasses and put them away.
