During world war i, buying war bonds was a way for people to
a) conserve resources
b) show patriotism
c) support peace
d) eliminate debt

B) show patriotism.

Explanation:

War bonds were issued by the government of United States as a form of debit securities during the World War II. The citizens could borrow money to the government to finance military needs or acts and defence. The government appealed to the United States citizens to buy the war bonds using the American patriotic spirit in his campaigns.

B) show patriotism

Explanation:

War bonds are a financial instrument used by states to finance military operations during a period of war. Like any other type of bond, interest accrues and the State amortizes the debt (that is, the State acquires a debt with an individual or an institution and has to return the borrowed money to the creditor and pay the corresponding interest). These bonds are also subject to classification by independent organizations that evaluate the security of the bond.

They can be guaranteed or not, and have a duration of short, medium or long term. Even if the bonds are guaranteed, if the issuing government is in bad shape after the war, the creditor runs the risk of losing the money invested.

a. always outside of government control.

answer:   migrations were important in the neolithic period. "two major migrations passing through southeastern europe were confirmed by the means of archaeo-genetic studies."

the first migration was the early neolithic period -- 6,000 before common era (bce) -- when the first farmers, from anatolia -- asia minor -- spread through europe. the second migration occurred during the early bronze age (3,000-2,500 bce) when the so-called "steppe population," from the eurasian steppe, replaced much of northern europe's previous population.

the first farmers of northern and western europe passed through southeastern europe with limited hunter-gatherer genetic admixture, which occurs when two or more previously isolated populations begin interbreeding. however, some groups that remained mixed extensively -- without the male-biased, hunter-gatherer admixture that prevailed later in the north and west, according to latest discoveries. southeastern europe continued to be a nexus between east and west, with intermittent genetic contact with the steppe people up to 2,000 years before the migrations that replaced much of northern europe's population.

"in some places, hunter-gatherers and incoming farmers seem to have mixed very quickly," says iain mathieson, a geneticist at the university of pennsylvania, who was first author of the paper. "but, mostly, the two groups remained isolated, at least for the first few hundred years. these hunter-gatherers had been living there for thousands of years, and it must have been quite a shock to have these new people show up -- with a completely different lifestyle and appearance."
