Which species has a lifespan range of 3-4 years?

Explanation:
Understanding typical lifespans of common laboratory rodents helps explain this. Gerbils tend to live about 3 to 4 years in captivity, which matches the given range well. Mice usually average around 1.5 to 2.5 years, sometimes a bit longer but not typically reaching 3–4 years. Rats generally live a bit longer than mice, commonly about 2 to 3.5 years, with many falling short of a full 4 years. Hamsters are usually in the 2 to 3-year range. Since gerbils consistently fit the 3–4 year window, they are the best match. Lifespan can vary with strain, housing, diet, and health, but the typical expectation for gerbils aligns with that 3–4 year range.
