i need 5 points though

Explanation:

because

Between 1820 and 1860 most immigrants came from northern and western Europe. The potato famine in Ireland ( 1845-1847) brought large number to the United states. The unsuccessful 1848 Revolution in Germany also created considerable emigration. Other came from Sweden, Norway, Denmark, England, Scotland and Wales

Explanation: That's my answer

the pogroms became known as kristallnacht, the "night of shattered glass," for the shattered glass from the store windows that littered the streets. the morning after the pogroms 30,000 german jewish men were arrested for the "crime" of being jewish and sent to concentration camps, where hundreds of them perished.

no options provided, here,but the answer to this question is often: a historian cites a japanese newspaper article published a year after the end of world war ii in order to draw conclusions about the effect of the war on the japanese economy.

clearly from the answer, the historian alludes to historical sources,and records to aid in analyzing and drawing conclusion on the effect of the war on the economy of japan.
