The authors states: nevertheless, although undeniably a shrewd politician, an exceptional general, and an insightful administrator, he owed his lasting success not to superior ability in any of these areas over nobunaga or hideyoshi, but to personal longevity and judicious institutional borrowing. born within a decade of his erstwhile overlords, he outlived nobunaga by thirty-four years and hideyoshi by eighteen. the authors credits ieyasu success to his longevity. does the author support this claim with an adequate explanation? a. the author provides an in-depth explanation to his claim that success was due to longevity. b. the author merely mentions the years ieyasu outlived his counterparts but does not provide enough evidence to support his claim. c. the author does not provide much information but he is able to explain his reasoning quite well.

The correct answer is B. The author merely mentions the years leyasu outlived his counterparts but does not provide enough evidence to support his claim.  

The author  highlights the abilities of Leyasu as a politician, and mentions the admirable work made in all the areas such as being a remarkable general and administrator, he also mentions the  fact that he lived and survived certain events, however, the author does not provide explicit examples of what was done in order to suport the statement given, therefore, the correct answer is letter B.

according to the quotation from booker t. washington's 1895 atlanta compromise speech.

in the great leap from slavery to freedom . . the masses of us are to live by the production of our hands . . we shall prosper . . as we learn to dignify and glorify common labor.

washington believed that  hard work had its own kind of dignity.
