Answer 1

اونایی که هایلایت شده رو درست ترجمه کردید، اما  control for sth با control sth  فرق می کنه. 

control for, Statistics. to account for (variables in an analysis) by limiting the data under consideration to a comparison of like things:

Control For: As used in the following way: "The effect of X on Y disappears when we control for Z", the phrase means to regress Y on both X and Z, together, and to interpret the direct effect of X as the only effect. Here the effect of Z on X has been "controlled for". It is implied that X is not causing changes in Z.

نمی دونم به فارسی باید چی ترجمه بشه دقیقا.
