1) To erase or not to erase? (2) That is the question in many students’ minds after they've penciled in one of those small circles in multiple-choice tests. (3) Folk wisdom has long held that when answering questions on such tests—or on any test—you should trust your first instincts. (4) However, a research instructor has found that students who change answers they’re unsure of usually improve their scores. (5) The instructor spent three years compiling and analyzing college students’ tests, watching for telltale erasure marks, which would indicate that the student had, indeed, revised his or her answer. (6) What the instructor found was that revised answers were two-and-a-half times as likely to go from wrong to right as vice-versa. (7) This statistic held up even across such variables as sex, age, and race; the subject matter of the tests studied also proved not to be a factor.

What caused the american civil war? there were many reasons for a civil war to happen in america, and political issues and disagreements began soon after the american revolution ended in 1782. between the years 1800 and 1860, arguments between the north and south grew more intense. one of the main quarrels was about taxes paid on goods brought into this country from foreign countries. this tax was called a tariff. southerners felt these tariffs were unfair and aimed toward them because they imported a wider variety of goods than most northern people. taxes were also placed on many southern goods that were shipped to foreign countries, an expense that was not always applied to northern goods of equal value. an awkward economic structure allowed states and private transportation companies to do this, which also affected southern banks that found themselves paying higher interest rates on loans made with banks in the north. the situation grew worse after several “panics,” including one in 1857 that affected more northern banks than southern. southern financiers found themselves burdened with high payments just to save northern banks that had suffered financial losses through poor investment. which sentence from the selection states a major detail that supports the main idea? a there were many reasons for a civil war to happen in america, and political issues and disagreements began soon after the american revolution ended in 1782. b taxes were also placed on many southern goods that were shipped to foreign countries, an expense that was not always applied to northern goods of equal value. c the situation grew worse after several "panics," including one in 1857 that affected more northern banks than southern. d this tax was called a tariff. e between the years 1800 and 1860, arguments between the north and south grew more intense.
