Using "and" to end a list with an "and" phrase [duplicate]

Solution 1:

Using "and" in this case is correct, though could perhaps be clarified by reworking the list. "As well as" is not equivalent to "and", and would be incorrect here (Chicago Manual of Style 6.18):

Note that the phrase as well as is not equivalent to and.

In this particular case, it may be that the list needs to be reworked. It reads awkwardly entirely apart from the dual "and". "Sciences and technology" is an odd phrasing, as is "human and social sciences". One would expect either "science and technology" or "sciences, technology", and "humanities and social sciences". This might not be possible to change, however, if the study itself or the school(s) at which it was conducted divide the subjects in this manner.

Regardless of whether you change the "and", you definitely want to keep the Oxford comma.
