You say potato and I say potatoe. The agency says "clarifications" and the protestor says "discusssions." In TDS, Inc., B-292674, GAO says, "discussions":

We find, despite the agency's characterization of the exchanges, that discussions occurred here. [3] The FAR anticipates “dialogue among the parties” in the course of an oral presentation, FAR § 15.102(a), and we see nothing improper in agency personnel expressing their view about vendors' quotations or proposals, in addition to listening to the vendors' presentations, during those sessions. Once the agency personnel begin speaking, rather than merely listening, in those sessions, however, that dialogue may constitute discussions. As we have long held, the acid test for deciding whether an agency has engaged in discussions is whether the agency has provided an opportunity for quotations or proposals to be revised or modified. See, e.g., Priority One Servs., Inc., B‑288836, B-288836.2, Dec. 17, 2001, 2002 CPD ¶ 79 at 5. Accordingly, where agency personnel comment on, or raise substantive questions or concerns about, vendors' quotations or proposals in the course of an oral presentation, and either simultaneously or subsequently afford the vendors an opportunity to make revisions in light of the agency personnel's comments and concerns, discussions have occurred. See FAR § 15.102(g).
