In your opinion, what is an example of an innovative solution to an engineering problem? Explain briefly why you chose this answer.
Explanation:
One of the things I’ve been writing and talking about a lot lately is the fact that solving problems collaboratively is an incremental process. In fact, in my book, Lost at School, I made mention of the fact that the model could just as easily have been called Incremental Problem Solving or Progressive Problem Solving. I thought the collaborative aspect of the model was the most important to emphasize, but that doesn’t mean that the incremental component isn’t almost as crucial. Often people who are new to the model enter the process of resolving a problem as if it’s a one-shot deal. If you have experience in using Plan B, you already know that most problems require more than one visit to Plan B to resolve. In other words, longstanding, complicated problems aren’t likely to be resolved the first time you try to discuss them. There’s a lot of information to be processed before a given problem can be solved. You need to gather information so as to achieve the clearest possible understanding of the kid’s concern or perspective on the problem (for the unfamiliar, that’s called the Empathy step). Then, you need to be clear about and articulate your own concern (that’s the Define the Problem step). Then, you’ll want to brainstorm with the kid so as to consider the array of potential solutions that could be applied to the problem and consider whether each solution truly addresses the concerns of both parties (that’s the Invitation). There’s a good chance you won’t even make it through all three steps of Plan B in the first attempt on a given unsolved problem (nor should you necessarily even try). If Plan B were a “technique,” then disappointment over not making it through all three steps in one conversation would be understandable. But Plan B is not a technique, it’s a process. As I’ve often emphasized, if you only make it through the Empathy step in the first attempt at Plan B on a given problem but you emerge with a clear sense of a kid’s concern or perspective on a problem that’s been causing significant angst or conflict, that’s quite an accomplishment. You’ll get back to the remaining steps at your earliest opportunity. There’s also an excellent chance the first solution you and the kid agree on won’t solve the problem durably. As you may know, this is usually because the original solution wasn’t as realistic and mutually satisfactory as the two parties first thought. But it could also be because the concerns weren’t as clear or simple as it first seemed. If a solution doesn’t stand the test of time, your goal is to figure out why, which means gathering additional information about the concerns of the two parties and why the solution may not be working so well. Plan B should always conclude with both parties agreeing to return to the problem if the solution being agreed upon doesn’t solve the problem durably. So if your enthusiasm for Plan B waned because your first solution didn’t stand the test of time, take heart: that’s not unusual. Many people enter Plan B with great hope, eager to see their new approach to helping a challenging kid pay quick dividends. In fact, Plan B may well pay quick dividends…not necessarily because the problem is yet durably solved, but because of the relationship- and communication-enhancing that occurs. And while the occasional problem – often simple ones – can be resolved with one visit to Plan B, now you know that several repetitions of Plan B may be necessary on each unsolved problem.

2.7 Code Practice: Question 1
Write a program that takes three numbers as input from the user and prints the largest
Can someone please help me with this because I’ve been struggling all day
Answer:
You didn't specify the programming language
I'll answer using Python
nums = []
for i in range(1,4):
inp = int(input("User Input: "))
nums.append(inp)
nums.sort()
print(nums[-1])
Explanation:
I made use of list in answering this question.
Start by declaring an empty list
nums = []
Use iteration to enter the list elements
for i in range(1,4):
inp = int(input("User Input: "))
nums.append(inp)
Sort the list
nums.sort()
Then print the element on the last index
print(nums[-1])
The code below is in Java
It uses if-else structure to find out the largest number among three numbers given by the user.
Comments are used to explain each line of the code
//Main.java
import java.util.Scanner;
public class Main
{
public static void main(String[] args) {
//Create a Scanner object to be able to get input
Scanner input = new Scanner(System.in);
//Declare the variables
int number1, number2, number3, largest;
//Ask the user to enter three numbers
System.out.print("Enter the first number: ");
number1 = input.nextInt();
System.out.print("Enter the second number: ");
number2 = input.nextInt();
System.out.print("Enter the third number: ");
number3 = input.nextInt();
/*
Check if the first number is greater than or equal to the second and third number.
If it is, the largest is the first one.
Otherwise, check if the second number is greater than or equal to the first and third number.
If it is, the largest is the second one.
If the previous conditions are not satisfied that means third is the largest one
*/
if(number1 >= number2 && number1 >= number3)
largest = number1;
else if(number2 >= number1 && number2 >= number3)
largest = number2;
else
largest = number3;
//Print the largest number
System.out.println("The largest number is " + largest);
}

NoSQL databases:________.
a) are geared toward transaction consistency; not performance.
b) support only small amounts of sparse data.
c) provide fault tolerance.
d) are based on the relational model.
Answer:
Option c (provide fault tolerance) is the appropriate choice.
Explanation:
NoSQL databases often recently attracted considerable attention as they would be easier to configure, provide enhancing understanding as well as appear to always have quicker data recovery intervals. They become quicker and simpler to manage but also have not the same standards and monitoring methods.Some other options in question are not relevant to something like a particular circumstance. So that the option above will be the appropriate one.
Answer:
c) provide fault tolerance.
Explanation:
Fault tolerance means the ability of a computer or network to continue working without any interruption when any of its components fail. Fault tolerant systems use backup components that takes place of the failed components so that there is no loss of service. In cases of failure the system can continue at a reduces level instead of failing completely. SQL database is not fault tolerant so it willl not function in case of interruption or system failure.

Sarah Jones is a coder who is working with a team to create a new mobile operating system. At their last meeting, the team discussed whether to make the code open source or closed source. What are benefits to each for the developer and for the user? What responsibility does the developer have to ensure the quality of an open source program?
Explanation:
Open-source software in simple terms refers to software whose source code can be changed by another developer other than the original developer (the original creator).
Benefits:
it allows improvementsit is easy to get tutorials about the software from several developers.fewer usage restrictionsA Closed-source software does not allow modification, in other words, it means programmers cannot improve the program expect if given permission by the creators.
To ensure the quality of the program the developer needs to perform periodic internal testing.
The benefits to each for the developer and for the user are:
It allows for modifications.It is easy to learnThere are few restrictions.What is an Open Source Software?This refers to the type of software in which the source code can be modified by another developer.
With this in mind, we can see that a closed source software is rigid and does not allow modifications which leads to the writing of code from scratch.
