Given the following passage  "An important property of light fixtures is the luminous efficacy or wall-plug efficiency, meaning the amount of usable light emanating from the fixture per used energy, usually measured in lumen per watt. A fixture using replaceable light sources can also have its efficiency quoted as the percentage of light passed from the "bulb" to the surroundings. The more transparent the lighting fixture is, the higher efficacy. Shading the light will normally decrease efficacy but increase the directionality and the visual comfort probability.",  answer the following question. Note that the answer is present within the text.  Question: What ratio is used to determine efficacy?
Ans: the amount of usable light emanating from the fixture per used energy, usually measured in lumen per watt

Given the following passage  "Before 2006, geneticists had largely attributed the ethnogenesis of most of the world's Jewish populations, including Ashkenazi Jews, to Israelite Jewish male migrants from the Middle East and "the women from each local population whom they took as wives and converted to Judaism." Thus, in 2002, in line with this model of origin, David Goldstein, now of Duke University, reported that unlike male Ashkenazi lineages, the female lineages in Ashkenazi Jewish communities "did not seem to be Middle Eastern", and that each community had its own genetic pattern and even that "in some cases the mitochondrial DNA was closely related to that of the host community." In his view this suggested "that Jewish men had arrived from the Middle East, taken wives from the host population and converted them to Judaism, after which there was no further intermarriage with non-Jews."",  answer the following question. Note that the answer is present within the text.  Question: What was notable about the female Ashkenazi population's DNA?
Ans: did not seem to be Middle Eastern
