Answer 1

A, the Bland-Allison Act. 
It was an act in 1878 with the U.S. Congress requiring the U.S. Treasury  to buy a certain amount of silver and to put it into circulation as silver dollars. 

Answer 2

The correct answer is A) Bland-Allison Act.

The Act that re-established the silver dollar as a form of currency and committed the U.S. government to the purchase of a certain amount of silver each month for coinage was the Bland-Allison Act.

The Bland-Allison Act of 1878 ordered the Treasury Department the purchase of two to four million dollars in silver so it could be converted into American dollars. It benefited the interests of the miners and farmers. Farmers wanted inflation to rise so they could benefit. William Allison -a Republican Senator- and Richard Bland -a Democrat Representative- were the creators of the Act that was vetoed by President Hayes. Congress overrode the veto in February 1878.
