Answer:
The best answer to your question: What was one significant accomplishment of the Hoover administration during his first year in office, would be, B: Creation of a federal agricultural program to regulate farm prices.
Explanation:
Herbert Hoover became the 31st president of the United States right when the country, and the world, was on the verge of a major financial crisis; the Great Depression. Although Hoover attempted several policies to try and help change the situation, both his conservative views on government interventionism, and other factors, prevented these policies from having the desired effect. Among the many areas of American life in which Hoover attempted to help with his policies, was the agricultural field. As such, in 1929 he signed into law the Agricultural Maketing Act, and established with it the Federal Farm Board, which attempted to stabilize prices through cooperatives and corporations, ensure the proper sale of American agricultural products and also ensure the buying of the surplus production by the federal government to help with the stabilization of prices. This is why the answer is B.
Based on the choices of the, and if we arrange that, here is the sequence.
1. The bill is introduced in Congress.
2. The bill passes in both houses.
3. The bill is send to the president.
4. The president signs or vetoes the bill.
It is assumed that, following the sequence, then the second step in the bill process is "The bill passes in both houses."
During World War I, 116,516 US soldiers were killed and 204,002 were wounded. If you add those two numbers together, the total number of US soldiers killed or wounded was 320,518.
You can represent that as a fraction of the current population of Chicago like this:

For simplicity's sake (since I assume the Chicago population number is an estimate), let's round the number of soldiers killed or wounded down to 300,000. That would look like this:

We can simplify that down a lot by dividing the number of soldiers and the number of Chicagoans by the least common denominator of 300,000. That would give us this fraction:

So for every 1 US soldier killed or wounded in World War I, there are 10 Chicagoans living in the city today.
