An<u> existence check</u> is a data validation rule that should be applied to mandatory data articles.
<h3>What are the rules of data validation?</h3>
What are data validation rules Data validation rules control what constants can be joined into a cell, e.g. any whole number between 0 and 9, or one of several values from another part of the spreadsheet
<h3>What is a presence check?</h3>
A method of verification that checks if the user has entered some data. This is sometimes described as a “required field” when completing an online form. Reality checks are important as they help to avoid accepting partial information which cannot be rectified later.

Complete question is,
• A synchronic check
• Range check
• Sequence check
• Existence check
Found the same question with the choices;
A. Reason Effectively
B. Solve Problems
C. Communicate Clearly
D. Use System Thinking
I would say the answer is A.
Answer:
Prioritization is an example of a skill that helps you reach long term goals because
it helps you stay organized and determined. It's scientifically proven that we can't multitask, effectively at the very least. So when you really consider what is most important to you at any given moment, it will help you succeed because chances are if you like what you are doing you are more likely to do well at it.
Answer:
Option 3 is the correct answer.
Explanation:
- In c, c++ or Java programming language, The for loop takes three parameters in which first is an initialization, second is condition check and the third is an increment. None of the other loop (except for loop) takes three parameters. The other loop takes only one parameter and that is the condition check.
- So when a user knows about the times of iteration then it is a good choice to use the for loop but when the person does not know about the times of iteration if the loop. It means the iteration of the loop is based on the condition then it is a good choice to chose while or Do-while loop.
- The above question wants to ask which loop for a user can best if he familiar with the iteration of the loop then the answer is for loop which is started from option 3. Hence Option 3 is the correct answer while the other is not because--
- Option 1 states about the do-while loop which takes condition only.
- Option 2 states about the while loop which also takes condition only.
- Option 4 states about the infinite loop which is not any loop.
- Option 5 states about none of these which is not correct because option 3 is the correct answer.
