Question: what sentence best describes ms. jackson's purpose in her cover letter's introduction?

heres the cover letter:
i am currently a special agent located in baltimore, and am in the process of requesting transfer to ncavc. although i have been informed that these highly competitive positions are normally reserved for special agents with more experience than i have yet accumulated, i feel that my exceptional performance in the field warrants my consideration.

after graduating at the top of my class at quantico, i promptly demonstrated excellent ability by solving my first assignment within a matter of days. although the case had been open for almost six months, information i derived by scrutinizing the financial records of the key suspects led to their immediate arrest and conviction. since then, my record has improved. as assistant director walter schmidt will attest, i have demonstrated the commitment, ability, and expertise of a special agent well beyond the expectations my relatively short experience would normally incur.

in particular, my ability to analyze information quickly and accurately—often resulting in extremely short case duration—lends itself to the needs of ncavc. time and again i have been called on in situations of extreme duress and apparent dead ends and produced results in a short period of time. in fact, several special agents in the ncavc have called upon my abilities and expertise in a number of situations, in which i have produced the results i am accustomed to (see references).

although i am going through regular channels in my application, i would greatly appreciate a quick review of my case history and demonstrated performance and perhaps a good word from your direction. i will contact you within a week to answer any questions. you very much for your consideration.

sincerely,

aurora jackson
