Question: I know that the answer to the question "How distant were the black students at Harvard to their ancestors?" is in "During a panel discussion at Harvard University's reunion for African American alumni during the 2003–04 academic year, two prominent black professors at the institution—Lani Guinier and Henry Louis Gates—pointed out an unintended effect of affirmative action policies at Harvard. They stated that only about a third of black Harvard undergraduates were from families in which all four grandparents were born into the African American community. The majority of black students at Harvard were Caribbean and African immigrants or their children, with some others the mixed-race children of biracial couples. One Harvard student, born in the South Bronx to a black family whose ancestors have been in the United States for multiple generations, said that there were so few Harvard students from the historic African American community that they took to calling themselves "the descendants" (i.e., descendants of American slaves). The reasons for this underrepresentation of historic African Americans, and possible remedies, remain a subject of debate.". Can you tell me what it is?
Answer: multiple generations

Question: I know that the answer to the question "What is the first 2nd and 3rd bird mentioned with a short incubation?" is in "Incubation, which optimises temperature for chick development, usually begins after the last egg has been laid. In monogamous species incubation duties are often shared, whereas in polygamous species one parent is wholly responsible for incubation. Warmth from parents passes to the eggs through brood patches, areas of bare skin on the abdomen or breast of the incubating birds. Incubation can be an energetically demanding process; adult albatrosses, for instance, lose as much as 83 grams (2.9 oz) of body weight per day of incubation. The warmth for the incubation of the eggs of megapodes comes from the sun, decaying vegetation or volcanic sources. Incubation periods range from 10 days (in woodpeckers, cuckoos and passerine birds) to over 80 days (in albatrosses and kiwis).". Can you tell me what it is?
Answer: woodpeckers, cuckoos and passerine

Question: I know that the answer to the question "Who got to kick someone off the throne?" is in "The Greek kingdom of Bactria began as a breakaway satrapy of the Seleucid empire, which, because of the size of the empire, had significant freedom from central control. Between 255-246 BCE, the governor of Bactria, Sogdiana and Margiana (most of present-day Afghanistan), one Diodotus, took this process to its logical extreme and declared himself king. Diodotus II, son of Diodotus, was overthrown in about 230 BC by Euthydemus, possibly the satrap of Sogdiana, who then started his own dynasty. In c. 210 BC, the Greco-Bactrian kingdom was invaded by a resurgent Seleucid empire under Antiochus III. While victorious in the field, it seems Antiochus came to realise that there were advantages in the status quo (perhaps sensing that Bactria could not be governed from Syria), and married one of his daughters to Euthydemus's son, thus legitimising the Greco-Bactria dynasty. Soon afterwards the Greco-Bactrian kingdom seems to have expanded, possibly taking advantage of the defeat of the Parthian king Arsaces II by Antiochus.". Can you tell me what it is?
Answer:
Euthydemus
