You should answer in whole sentences in your own words. The maximum word limit for Question 1 is 150 words.

Question 2
This question is concerned with an extension to the flashcard problem you studied in Block 3 Part 2. In the original flashcard problem, a user can ask the program to show an entry picked randomly from a glossary. When the user presses return, the program shows the definition corresponding to that
entry. The user is then given the option of seeing another entry or quitting. A sample session might run as follows:

Enter s to show a flashcard and q to quit: s Define: word1 Press return to see the definition definition1 Enters to show a flashcard and q to quit: s Define: word3 Press return to see the definition definition3 Enter s to show a flashcard and q to quit: q The flashcard program is required to be extended as follows:

Box 1 – Specification of extended problem 
As well as being offered a choice between seeing a flashcard or quitting, the user is offered the option of seeing a definition first.

If the user chooses this option, the program picks an entry at random from the glossary and shows the definition for that entry. It then asks the user what word is being defined. When the user presses return the program shows the word concerned. The user is then given the option of seeing another flashcard, seeing another definition, or quitting. Apart from this the program behaves like the original version A sample dialogue might run as follows: (the additional dialogue is underlined.)

Enter s to show a flashcard, d to see a definition, or q to quit: s Define: word3 Press return to see the definition definition3 Enter s to show a flashcard, d to see a definition, or q to quit: d What word is defined by: definition2 Press return to see the word word2 Enter s to show a flashcard, d to see a definition, or q to quit: q

Question 4
This question is about Block 3 Part 4. In Sections 4.1 and 4.2, we explored how the TOR network allows a certain amount of anonymity on the Internet and how this led to the “Darknet”. While many of the services provided on the Darknet, using TOR, are illegal, immoral and unethical, some have started to argue that this reputation is limiting the use of TOR.

For this question, we want you to explore this debate. Start by reading this article on The Conversation:

Describe how the TOR network provides anonymity and how this can be used for both positive and negative purposes. In your description, come to a conclusion as to whether you think more people should use the TOR network or not.
