What are the advantages of being able to change the U.S. Constitution? Explain these advantages. Give your opinion of a current law that you believe should be changed, and why. Come back in a couple of days and post a comment to one of your classmates stating whether you agree with the law they've earmarked that needs to be changed, and if you think their reason is a strong, or a valid explanation for the needed change.

2. In this section you will be shown several classes. Inside the code for each class will be a question. You should provide your answer to the question inside the chart. Many of the questions will ask you whether a variable has changed or not. In cases that the variable being asked about is a primitive type, you should provide your answer based on the data stored in the primitive type. In cases that the variable being asked about is a reference type, you should provide your answer based on the data stored at the Object linked to by the reference type. For example, in the first snippet, the question asks about the variable x defined in the main method. Since x is a primitive type, you should answer YES if you think the variable x has had its value changed after the method methodOne() returns. All your answers should go in the chart below: (9 points) Part Answer to question x changed (circle one)? YES NO y changed (circle one)? a changed (circle one)? b changed (circle one)? d1 a changed (circle one)? b changed (circle one)? YES e words changed (circle one)? YES NO Values in array of array referred to by y: What is printed to the screen? (a) public class ReferenceTesti public static void methodOne (int x){ x++; public static void main(String[args) { int x = 0; methodOne (x); //IS THE DATA STORED OR REFERRED TO BY X THE SAME? (ANSWER IN CHART)

The Giza Zoo is one of the biggest and oldest zoos in the Middle East zoological gardens. The Giza Zoo administration has come up with some efforts to improve the zoo conditions to give zoo-visitors new experiences during their visit. The zoo administration wants to implement an interactive information point/ kiosk where visitors would use a menu to select information about animals. The menu includes 500 different animals. The information is provided only using high-definition video with an audio track.

1. Which computer hardware device(s) would you recommend/ be best used as an interactive information point for the zoo.
2. State reasons why you chose a) above.
3. What type of input device does the selected device use?
4. Provide TWO (2) advantages of display devices.
5. Mention THREE (3) disadvantages of using this device.
6. Name TWO (2) other types of input devices that make use this type of device.
7. Mention TWO (2) jobs that can benefit from using interactive whiteboards. Explain each of your answers.

Carol holds a two-digit number X and wants Alice and Bob to recover the number. She gives them the following information.

• Both Alice and Bob know that the number held by Carol is one of the following.

• 21  26
• 31  32  35
• 42  44
• 52  54  57
• 62  67

• Alice knows the number of ones of X but not the number of tens.
• Bob knows the number of tens of X but not the number of ones.

Alice and Bob exchange the following messages.

1. (a)  Bob to Alice: ’You might know X’.
2. (b)  Alice to Bob: ’I did not, but, after what you have said, I do’.

Based on the above information, please answer the following questions. For each question, please accompany your answer with a short explanation of why your believe your answer is correct. Marks will not be awarded for answers without any explanation.

1. (a)  Based on the statement of Bob it is possible to narrow down candidates for the number of tens from the initial five possibilities down to just two. What are these two possibilities? (7 marks)
2. (b)  Based on the ’I did not’ statement of Alice, the number of candidates for X can be narrowed down to just three. What are these candidates (6 marks)
3. (c)  The remaining part of Alice’s statement allows to identify X precisely. What is X? (7 marks)
