One example: Passage: Martin Luther married Katharina von Bora, one of 12 nuns he had helped escape from the Nimbschen Cistercian convent in April 1523, when he arranged for them to be smuggled out in herring barrels. Suddenly, and while I was occupied with far different thoughts, he wrote to Wenceslaus Link, “the Lord has plunged me into marriage. At the time of their marriage, Katharina was 26 years old and Luther was 41 years old. Question: In a letter who did Luther credit for his union with Katharina?
Solution is here: the Lord
Explanation: The paragraph clearly states that, Luther has credited the Lord for his union with Katharina, hence the Lord is correct answer.

Now, solve this: Passage: In many parts of the United States, after the 1954 decision in the landmark court case Brown v. Board of Education of Topeka that demanded United States schools desegregate 'with all deliberate speed', local families organized a wave of private 'Christian academies'. In much of the U.S. South, many white students migrated to the academies, while public schools became in turn more heavily concentrated with African-American students (see List of private schools in Mississippi). The academic content of the academies was usually College Preparatory. Since the 1970s, many of these 'segregation academies' have shut down, although some continue to operate.[citation needed] Question: What court case desegregated schools in the United States?
Solution:
Brown v. Board of Education of Topeka
