Elis [28]

The best answer — and correct answer — would be:

___________________________________________

  [C]: " histotechnologist" .

___________________________________________

Let us consider the other answer choices:

___________________________________________

[A]: "radiologist" — is a physician {M.D. or D.O.} who has been through medical school and has completed additional education and training in a "board-certified" specialty — ' radiology ' .   However, this would involve getting accepted into a medical school (with extensive prerequisites (pre-med courses in physics, calculus, chemistry, physics, and upper-division organic chemistry— often in addition to a 4-year Bachelors degree (of some sort) — while maintaining a high GPA, a well-rounded education, and many extensive extracurricular/volunteer/community activities.  Then, the medical school and post-residency would take time.  Also, a radiologist would work with people a lot, and [Navin] "tends to enjoy environments where he is on his own to do his work" .   Also, [Navin] is "getting ready to graduate college" — and despite having studies biotechnology, physiology, and chemistry, it is unlikely that he has completed "all of the premed course prerequisites" .

               So;  we can rule out "Choice [A] ".

____________________________________________

[B]:  "sonographer"   — is similar, in part, to an "radiographer" , or "x-ray technician" (not to be confused with "radiologist") .   Note that this career involves working directly with patients (and well as interacting people; such as many health care professionals).  

              So;  we can rule out "Choice [B]" .

_____________________________________________

 [D]: "paramedic" — involves working extensively with other people, and although there is some "lab results" involved, there is more communication with others (patients, emergency room staff, physicians, nurses, police offers).  So, this would not be the ideal career.

              So; we can rule out "Choice [D]" .

_____________________________________________

The correct answer is:  [C]: "histotechnologist" .

_____________________________________________

<u>Note</u>:  " histo- " = "tissue" .

  A "histotechnologist" essentially analyzes tissue samples/specimens using microscopes along with computer and other related and advanced technology and dealing with precise finding in a laboratory setting that involves a relative quiet environment (that does not deal directly with patients — but rather involves data analysis and documentation and recording).

 As such, a "histotechnologist" would be an ideal career choice — and would be the best/correct answer — among the answer choices given.

______________________________________________

Hope this answer helps.

Best wishes!
