Kate works for a local asset management firm. A broker is offering a new trading service to Kate, who originally provided Kate with proprietary research through client brokerage arrangements. Low-fee and execution-only trades are offered to complement its traditional full-service, execution-and-research trades. Moreover, the broker will apply the commissions paid on the new service toward satisfying the brokerage commitment of the prior full-service arrangements to entice Kate and other asset managers to send additional business its way. Kate has always been satisfied with the execution provided on the full-service trades, and the new low-fee trades are comparable to the fees of other brokers currently used for the accounts that prohibit soft dollar arrangements. Which of the following is correct regarding to Kate’s action? 这道题看不懂完全，麻烦详细解析下意思
