bought by the crew and officers to supplement the equally distributed
dried food rations, were tainted with lead.
Given the information above, which of the following, if true, would most
contribute to an explanation of the greater severity of lead poisoning
among the officers?

the crew ate all of their daily dried food rations while the officers
substituted canned food for most of their rations.
B The canned food produced in England in 1845 could last the dura-
tion of most extended voyages without becoming inedible.
COn average, the officers had spent less time at sea than had the
members of the working-class crew.
D The population of England in 1845 got much of its drinking water
from lead pipes that carried the waterfrom rivers and lakes,
thereby contaminating the water with lead particles.
