Einstein was urging roosevelt to speed up the work of fermi and szilard.
which piece of evidence best explains the reason he thought quick action was necessary?
(a)
the united states does not have much uranium to work with. there are better
reserves of uranium in canada and the former czechoslovakia.
(b)
keeping government departments informed about ongoing developments in
chain reactions, and recommending how the government might use this
research. particular attention should be given to the problem of low quantities of
uranium in the united states.
your contact could raise more funds from individuals who are willing to
donate to this cause. he could perhaps also seek cooperation from company
laboratories, which may be willing to donate necessary equipment.
i understand that germany has taken over mines in czechoslovakia and
stopped the sale of uranium from these mines. this early action might suggest
that germany knows about the work americans are doing with uranium.
(d)

athenian democracy developed around the fifth century bc in the greek city-state (known as a polis) of athens, comprising the city of athens and the surrounding territory of attica, and is often described as the first known democracy in the world. other greek cities set up democracies, most following the athenian model, but none are as well documented as athens'.

it was a political system of direct democracy, in which participating citizens voted directly on legislation and executive bills. participation was not open to all residents: to vote one had to be an adult, male citizen, i.e., not a foreign resident, a submissive or a woman, and the number of these was "probably no more than 30 percent of the total adult population."[1]

the longest-lasting democratic leader was pericles. after his death, athenian democracy was twice briefly interrupted by oligarchic revolutions towards the end of the peloponnesian war. it was modified somewhat after it was restored under eucleides; the most detailed accounts of the system are of this fourth-century modification rather than the periclean system. democracy was suppressed by the macedonians in 322 bc. the athenian institutions were later revived, but how close they were to a real democracy is debatable. solon (594 bc), cleisthenes (508/7 bc), and ephialtes (462 bc) contributed to the development of athenian democracy. cleisthenes broke up the power of the nobility by organizing citizens into ten groups based on where they lived rather than on their wealth.
