Easy answer you could have come up with by yourself I think. Crude oil, means oil straight from the ground and not refined yet. Heavy metals means not light metals. So not iron or sodium but Lead and other heavy stuff. Since oil comes from the ground and metals are mined from the ground, it makes sense that they could be found together. So if the teacher wants a different answer he should have said "how is crude oil formed" or something like that.

The specific gravity of heavy fuel oil can vary, but it typically ranges from 0.95 to 1.03. It is important to consult specific fuel oil specifications or test data to determine the precise specific gravity of a particular heavy fuel oil sample.
Heavy crude oil has a higher density and viscosity compared to light crude oil. Heavy crude oil also contains more impurities like sulfur and metals, which makes it more difficult and expensive to refine. Light crude oil is easier to extract, transport, and refine, making it more valuable in the market.
Japan does not have oil or prescious/heavy metals; such as copper, lead, tungston, etc.
