Question

7. For works with multiple authors, you may list the first author's name followed by which of the following that indicates there are multiple authors?
A. et all
B. and al.
C. et all.
D. et al.

Answer 1

The correct answer is D. et al.
This is short for Latin words et alia, which means 'and all.' However, the Latin version of the phrase (the shortened one) is used when citing rather than English (and all) because it looks fancier and more sophisticated and academic.
