Please answer this: Given the following passage  "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 the following question. Note that the answer is present within the text.  Question: What should be avoided if one wants the most efficient filament possible?
++++++++
Answer: cooling


Please answer this: Given the following passage  "Another extreme case of impedance matching occurs when using a small loop antenna (usually, but not always, for receiving) at a relatively low frequency where it appears almost as a pure inductor. Resonating such an inductor with a capacitor at the frequency of operation not only cancels the reactance but greatly magnifies the very small radiation resistance of such a loop.[citation needed] This is implemented in most AM broadcast receivers, with a small ferrite loop antenna resonated by a capacitor which is varied along with the receiver tuning in order to maintain resonance over the AM broadcast band",  answer the following question. Note that the answer is present within the text.  Question: What is first mentioned that is to blame?
++++++++
Answer: using a small loop antenna


Please answer this: Given the following passage  "In October 2013, the New York Post reported that Schwarzenegger was exploring a future run for president. The former California governor would face a constitutional hurdle; Article II, Section I, Clause V nominally prevents individuals who are not natural-born citizens of the United States from assuming the office. He has reportedly been lobbying legislators about a possible constitutional change, or filing a legal challenge to the provision. Columbia University law professor Michael Dorf observed that Schwarzenegger's possible lawsuit could ultimately win him the right to run for the office, noting, "The law is very clear, but it’s not 100 percent clear that the courts would enforce that law rather than leave it to the political process."",  answer the following question. Note that the answer is present within the text.  Question: What was the Constitution barring?
++++++++
Answer:
a future run for president
