  B. get time

What is a condition in computer science?

• A loop that runs indefinitely

• A set of instructions in plain language

• Something which can be true or false and is used to decide whether an action happens

• A diagram showing how a program will run

What is pseudocode?

• A diagram with arrows connecting different steps

• A statement with multiple possible outcomes

• A statement which must be true or false

• Instructions for how a program will work in plain language

What is a flowchart?

• A statement which must be true or false

• Instructions for how a program will work in plain language

• A diagram which shows how a program will run by connecting the different steps with arrows

• A set of rules that govern how a program operates

What is a Boolean?

• A type of loop in programming

• A diagram used in computer science

• 
  A statement which must be true or false, used as conditions in programming

• A set of instructions written in code

Why are conditionals useful in programming?

• They help in writing pseudocode more efficiently

• They can help decisions get made based on specific circumstances

• They are used to create flowcharts

• They replace the need for loops in a program

What can be challenging about writing pseudocode for complex programs like the "Race to the Finish" game?

• It is difficult to translate abstract ideas like computer code into everyday words

• It is too simple and does not cover all aspects of the program

• It requires the use of a specific programming language

• It cannot be used to connect different steps with arrows

How can pseudocode and flowcharts be useful before starting to code a program?

• They can be used to play the program like a game

• They help organize our thoughts and plan our code to work out potential bugs beforehand more easily

• They are only useful after the program has been fully written

• They replace the need for actual coding

How did loops help when used alongside conditionals in the program mentioned?

• 
  They allowed the program to skip checking for conditions

• 
  They made the program run slower

• They helped the program keep checking for the condition over and over again

• They were not necessary for the program to function

What is the outcome when the condition in the flowchart is true? And what is the outcome when it is false?

• If true, take sunglasses; if false, take umbrella

• 
  If true, take umbrella; if false, take sunglasses

• If true, start the program; if false, stop the program

• If true, write pseudocode; if false, create a flowchart
