Q: Selling two hundred thousand copies in its first month, the publication of The Audacity of Hope in 2006 was an instant hit, helping to establish Barack Obama as a viable candidate for president.
A: (choice E) The Audacity of Hope, published in 2006, was an instant hit: it two months, it sold two hundred thousand copies and helped establish its author, Barack Obama, as a viable candidate for president.
How can an answer choice E be correct? Choice E says ... in two months ... but the question said in "... in its first month ..." Where are they getting the two months from? Is that a mistake? I'm really curious. Btw, I chose "C".
