ONLY FOR SEMESTER 1 STUDENTS
ASSIGNMENT 01
Chapters 1, 2 and 3
Unique Nr.: 705199
Fixed closing date: 21 February 2020
Please note that as explained before, examination admission for this module is by obtaining
at least 40% in your year mark. Your year mark is the average of your best three assignment
marks out of four.
This multiple-choice assignment will be marked by computer. Hence the closing date is fixed and
no extension of time can be granted.
Your answers must be entered on an optical mark reading sheet. But before you attempt that,
please study in detail the relevant chapter of the publication Study @ Unisa. Please make sure
that you know how to handle the optical mark reading sheets, since sheets which are marked
incorrectly and which are rejected by the computer will not be marked by hand and students will
not receive marks for such assignments. The unique number appearing in the box above links
your assignment to the corresponding set of answers in the computer. It must therefore be filled in
correctly on the optical mark reading sheet.
Note that your assignment will not be returned to you. Please keep a record of your answers so
that you can compare them with the correct answers.
In each of the following ten questions, mark the number of the answer that you think is correct.
