Question: "What does Xenon gas do to electricity use when used in light bulbs?" Context: "While inert gas reduces filament evaporation, it also conducts heat from the filament, thereby cooling the filament and reducing efficiency. At constant pressure and temperature, the thermal conductivity of a gas depends upon the molecular weight of the gas and the cross sectional area of the gas molecules. Higher molecular weight gasses have lower thermal conductivity, because both the molecular weight is higher and also the cross sectional area is higher. Xenon gas improves efficiency because of its high molecular weight, but is also more expensive, so its use is limited to smaller lamps." Answer:
Ans: improves efficiency

Question: "Which of the following is not a period of time: past, dimensions, or future?" Context: "A psychological identity relates to self-image (one's mental model of oneself), self-esteem, and individuality. Consequently, Weinreich gives the definition "A person's identity is defined as the totality of one's self-construal, in which how one construes oneself in the present expresses the continuity between how one construes oneself as one was in the past and how one construes oneself as one aspires to be in the future"; this allows for definitions of aspects of identity, such as: "One's ethnic identity is defined as that part of the totality of one's self-construal made up of those dimensions that express the continuity between one's construal of past ancestry and one's future aspirations in relation to ethnicity" (Weinreich, 1986a)." Answer:
Ans: dimensions

Question: "Cork experiences how much celestial light?" Context: "Temperatures below 0 C (32 F) or above 25 C (77 F) are rare. Cork Airport records an average of 1,227.9 millimetres (4.029 ft) of precipitation annually, most of which is rain. The airport records an average of 7 days of hail and 11 days of snow or sleet a year; though it only records lying snow for 2 days of the year. The low altitude of the city, and moderating influences of the harbour, mean that lying snow very rarely occurs in the city itself. There are on average 204 "rainy" days a year (over 0.2 millimetres (0.0079 in) of rainfall), of which there are 73 days with "heavy rain" (over 5 millimetres (0.20 in)). Cork is also a generally foggy city, with an average of 97 days of fog a year, most common during mornings and during winter. Despite this, however, Cork is also one of Ireland's sunniest cities, with an average of 3.9 hours of sunshine every day and only having 67 days where there is no "recordable sunshine", mostly during and around winter." Answer:
Ans: an average of 3.9 hours of sunshine every day

Question: "What award did Tito receive from Japan?" Context: "Josip Broz Tito received a total of 119 awards and decorations from 60 countries around the world (59 countries and Yugoslavia). 21 decorations were from Yugoslavia itself, 18 having been awarded once, and the Order of the National Hero on three occasions. Of the 98 international awards and decorations, 92 were received once, and three on two occasions (Order of the White Lion, Polonia Restituta, and Karl Marx). The most notable awards included the French Legion of Honour and National Order of Merit, the British Order of the Bath, the Soviet Order of Lenin, the Japanese Order of the Chrysanthemum, the German Federal Cross of Merit, and the Order of Merit of Italy." Answer:
Ans: the Japanese Order of the Chrysanthemum
