QUES: The theory that race is merely a social construct has been challenged by the findings of researchers at the Stanford University School of Medicine, published in the American Journal of Human Genetics as "Genetic Structure, Self-Identified Race/Ethnicity, and Confounding in Case-Control Association Studies". One of the researchers, Neil Risch, noted: "we looked at the correlation between genetic structure [based on microsatellite markers] versus self-description, we found 99.9% concordance between the two. We actually had a higher discordance rate between self-reported sex and markers on the X chromosome! So you could argue that sex is also a problematic category. And there are differences between sex and gender; self-identification may not be correlated with biology perfectly. And there is sexism."
What may self-identification not correlate with precisely?

ANS: biology

QUES: In the medieval period the wall circuit was expanded. Via Vittorio Emanuele continued to be the main road east-west through the walled city. West gate was still Porta Nuova, the circuit continued to Corso Alberti, to Piazza Vittorio Emanuele Orlando where it turned east along Via Volturno to Piazza Verdi and along the line of Via Cavour. At this north-east corner there was a defence, Castello a Mare, to protect the port at La Cala. A huge chain was used to block La Cala with the other end at S Maria della Catena (St Mary of the Chain). The sea-side wall was along the western side of Foro Italico Umberto. The wall turns west along the northern side of Via Abramo Lincoln, continues along Corso Tukory. The wall turns north approximately on Via Benedetto, to Palazzo dei Normanni and back to Porta Nuova.

QUES: where  is the maximum possible exposure that does not lead to a clipped or bloomed camera output. Typically, the lower limit of the saturation speed is determined by the sensor itself, but with the gain of the amplifier between the sensor and the analog-to-digital converter, the saturation speed can be increased. The factor 78 is chosen such that exposure settings based on a standard light meter and an 18-percent reflective surface will result in an image with a grey level of 18%/√2 = 12.7% of saturation. The factor √2 indicates that there is half a stop of headroom to deal with specular reflections that would appear brighter than a 100% reflecting white surface.
What is the upper limit of saturation determined by?

ANS: unanswerable

QUES: On 1 April, Alexander addressed the Sénat conservateur. Long docile to Napoleon, under Talleyrand's prodding it had turned against him. Alexander told the Sénat that the Allies were fighting against Napoleon, not France, and they were prepared to offer honorable peace terms if Napoleon were removed from power. The next day, the Sénat passed the Acte de déchéance de l'Empereur ("Emperor's Demise Act"), which declared Napoleon deposed. Napoleon had advanced as far as Fontainebleau when he learned that Paris was lost. When Napoleon proposed the army march on the capital, his senior officers and marshals mutinied. On 4 April, led by Ney, they confronted Napoleon. Napoleon asserted the army would follow him, and Ney replied the army would follow its generals. While the ordinary soldiers and regimental officers wanted to fight on, without any senior officers or marshals any prospective invasion of Paris would have been impossible. Bowing to the inevitable, on 4 April Napoleon abdicated in favour of his son, with Marie-Louise as regent. However, the Allies refused to accept this under prodding from Alexander, who feared that Napoleon might find an excuse to retake the throne. Napoleon was then forced to announce his unconditional abdication only two days later.
Where had Napoleon advanced to when he received word that Paris was lost?

ANS:
Fontainebleau
