Another metaphor is that provenience is an artifact's "birthplace", while provenance is its "résumé", though this is imprecise (many artifacts originated as trade goods created in one region but were used and finally deposited in another). Aside from scientific precision, a need for the distinction in these fields has been described thus: In this context, the "provenance" can occasionally be the detailed history of where an object has been since its creation, as in art history contexts – not just since its modern finding. In some cases, such as where there is an inscription
Issues relating to biofuels energy sources will help to combat gasoline price spikes.

Therefore, it is not only that there is an increase in demand for the food staples, like
