Explanation:
The most appropriate change in this situation would be to change the message "User input deemed invalid" to "You made a mistake, try again, you can".
<h3>What should we change to improve the children's experience?</h3>
To improve children's experience with this new calculator program, we must adapt all the features of the program for children's users. Therefore, the buttons, the messages and everything related to this program must be suitable for their motor and brain development.
Therefore, it is considered that the message "User input deemed invalid" is not suitable for children because they may not understand this message or misinterpret it and desist from using the new program.
So, the most appropriate message to replace the previous message would be:
- "You made a mistake, try again, you can"
Because this message is suitable for the friendly language that children use in their daily lives and they would better understand the message without giving up using the new program or the calculator.

Answer:
Option d) B is 1.33 times faster than A
Given:
Clock time, 
No. of cycles per instructions, 
Solution:
Let I be the no. of instructions for the program.
CPU clock cycle, 
= 2.0 I
CPU clock cycle, 
= 1.0 I
Now,
CPU time for each can be calculated as:
CPU time, T = 
Thus B is faster than A
Now,
Performance of B is 1.33 times that of A
Answer:
A. Lookup
