The citation to the reference should have appeared in the second paragraph on page 2, thus the sentence:
Our experiment improves on the existing studies with a similar methodological design

should be replaced with:
Our experiment improves on the existing studies with a similar methodological design
(Christensen 2020; Goldberg 2021) in two major ways.1
And the reference is as follows:
