"No projects that involve historical restorations were granted building permits this month."
P1: IHR ==> not GBP GBP ==> not IHR
"Since some of the current projects of the firm of Stein and Sapin are historical restorations,"
P2: SS-some-IHR IHR-some-SS
"at least some of Stein and Sapin's projects were not granted building permits this month."
C: SS-some-not GBP not GBP-some-SS
Remember that when you want to combine a quantity statement with a Sufficient & Necessary statement, you have to arrange the premises so that the sufficient condition of the Sufficient & Necessary statement and the right-hand side variable of the quantity statement are the same, like so: SS-some-IHR ==> not GBP
We can then conclude: SS-some-not GBP. Therefore, this is a valid argument.
Now, let's diagram answer choice (D):
"Several films directed by Hannah Barker were released this season,"
P1: HB-some-RTS RTS-some-HB
"but none of the films released this season were enthusiastically reviewed."
P2: RTS ==> not ER ER ==> not RTS
"Therefore, at least some of Hannah Barker's films have not received enthusiastic reviews."
C: HB-some-not ER
We can arrange like so: HB-some-RTS ==> not ER.
Thus, we can conclude: HB-some-not ER.
So answer choice (D) has the same exact reasoning that we encountered in the argument.

Answer choice C raised a question for me. It starts with "Only" and later says "People who." How do we know which term over powers the other.

@KimJongUn I'm not sure I'm following your question here, so please let me know if I don't answer it to your needs. Both are important, and in this case work together. "Only [those] people who" is a regular LSAT way of specifying a specific group of people that have certain characteristics distinct from others. In C, it means that there's a rule that only people who completed their paperwork can be paid. We know that no new members did their paperwork, so they are not getting paid.
