Final answer:
The question seems to require analyzing the number of deaths due to motor vehicle crashes in 1990, but we need additional data to provide an accurate answer.
Step-by-step explanation:
The question appears to be about analyzing data related to fatalities due to motor vehicle crashes and comparing them to other causes of death. Specifically, it seems to ask for an approximate number of annual fatalities in 1990, likely related to crash data. To serve this analysis, the provided data regarding total number of crashes and fatalities for various years can be used along with information about the causes of accidental death in 1999 and 2014, as well as the death rate due to military conflict. However, without the specific number of deaths in 1990, exact comparisons for other accidental causes or conflicts cannot be confidently derived from the given data.
