Final answer:
A person with Latin American background, dark hair and eyes, who rarely burns is likely Fitzpatrick skin type IV, which tans easily and generally corresponds to Mediterranean, Hispanic, or Asian heritage.
Step-by-step explanation:
The person in question, with Latin American heritage, dark hair, dark brown eyes who rarely burns, would most likely fall under Fitzpatrick skin type IV.
The Fitzpatrick scale is a numerical classification schema for human skin color based on the skin's reaction to sun exposure in terms of the degree of burning and tanning. According to the scale, Type IV skin is characterized by olive to moderate brown skin that tans easily and burns minimally. This skin type is common among people of Mediterranean, Hispanic, and some Asian descents. Given the description of rarely burning yet maintaining a darker natural pigmentation, this individual is unlike the lighter Type II or III and does not match the darker complexions of Type V and VI, which are more typical in people of African and Middle Eastern descent.
