Which technique provides an age with a specific date range?

Explanation:
Providing a calendar-date age for organic remains relies on a method that yields a concrete time window in years. Radiocarbon dating measures the remaining carbon-14 in once-living material and, using the known decay rate, estimates how long it has been since the organism died. Because measurements have uncertainty and atmospheric carbon-14 has varied over time, labs report a date with a range—and after calibrating with curves that translate radiocarbon years into calendar years, you get a specific date range. It’s suitable for organic samples and works best for relatively recent times, up to about 50,000 years ago. Fluorine dating, stratigraphy, and seriation don’t provide exact calendar dates. Fluorine dating compares how much fluorine bones have absorbed to estimate relative burial times. Stratigraphy arranges layers to show sequence rather than exact years. Seriation orders artifacts by stylistic changes over time, giving relative ages rather than precise dates.
