The Shroud of Turin is arguably the most studied relic in history. Some evidence suggests that the shroud is the authentic burial cloth of Jesus Christ. In 1988 a small sample of the shroud was studied using an accelerator mass spectrometer (AMS) which is able to detect levels of 14C. Assume that the background level of 14C in 1988 was 100. dpm (disintegrations per minute) and the radiation detected in the sample was 91.9 dpm. Using this data, what is the approximate age of the sample taken from the shroud? The half-life of 14C is 5730 years.

A) 700 years. B) 1800 years. C) 1300 years. D) 2000 years. E) 200 years.
