my question in lecture 3

advertisement and scientific papers
don't
always
usually
show similarities.


note:
in the beginning of the lecture our doctor mentioned this sentence
- advertisement may show similarities but they are not the same


the first option (don't) is wrong
that leads us to the last tow options which are "always" and "usually", what is the right answer???? ha
