In the Taylor et al. study, researchers used a mixed experimental design in which one variable, , could not be manipulated, and thus it is called a subject variable. They did, however, manipulate , and thus, this is a(n) variable.

D). Culture; Support condition; independent.

Explanation:

As per the given description, 'culture' i.e. 'the dependent variable' which is characterized as 'subject variable' as it could not be adjusted or manipulated while 'the support conditions' could be manipulated or controlled in order to observe its impact on the dependent variable and thus, it is considered to be the 'independent variable'. 'Culture' is considered to be the 'dependent variable' as it is dependent on various other factors and represents the outcome of manipulation of the independent variable while the 'subject conditions' or the independent variable act as inputs to observe the impacts and reach worthy conclusions. Thus, option D is the correct answer.
