A job placement agency helps match job seekers with potential employers. The agency would like to design a simulation in order to help predict the likely job placement outcomes for job seekers based on historical trends and patterns. Which of the following is most likely to be a benefit of the simulation?

• The computer simulation will be able to include more details and complexity than the real-world job placement process.

• The computer simulation could test hypotheses about patterns in the job placement process that are costly or time consuming to observe in reality.

• The computer simulation will be able to precisely predict the real-world outcomes for each job seeker.

Which of the following is the same loop just written differently? There are two answers.

• 
• 
• for the variable i, while i is less than 4, add one to the variable and move forward once

• for the variable i, if i is greater than 4, move forward 4 times and add one to the variable
