Feedback
This quiz contributes 10% towards your final semester mark.
If you passed the assessment, well done! If you want to do another attempt, remember that you only have
3 attempts, of which the highest mark will be considered.
IMPORTANT: It remains the responsibility of each student to manage additional attempts carefully and
responsibly. Additional attempts are not intended to give students extra chances to improve their marks
but rather to help them complete the assessments despite the issues they may face. We strongly suggest
that should you experience any MyUnisa issues or loadshedding, log out of the system and complete
your other attempts at another date or time. Suppose all three attempts are unsuccessful (i.e. you
received a mark of 0% for all three attempts), you can contact the lecturer via email (azizz@unisa.ac.za)
(not the message function on myUnisa) with screenshots for assistance. Please only contact the lecturer
if all three attempts are unsuccessful.
If you failed this attempt and have more attempts left, rather study the prescribed content again
before using your final attempt.
If this was your final attempt and you have failed, we suggest that you spend more time studying the
prescribed content before a quiz.

Question 1
Correct
Mark 1.00 out of 1.00
Consider a five-mile-long railroad tunnel. Tunnel experts and advocates estimate the total cost to be R200 million. What is the
reference class for this project? But reference class projects in this area have been over-budget by 30%. So, what should the
actual revised budget number be for this proposed five-mile tunnel project?
a. Past bridge projects, R230 million
b. Past tunnel projects, R260 million
c. Past highway projects, R200 million
d. Past building projects, R230 million
e. Past construction projects, R230 million
Your answer is correct.
The reference class for this project should be old tunnel projects in the area. The revised budget should be the original budget
plus 30% of the original budget or R260 million in this case.
The correct answer is:
Past tunnel projects, R260 million
