In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Ex Input:
What is a prerequisite for weight to play a factor in conductivity?, 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.

Ex Output:
constant pressure and temperature


Ex Input:
What controlling entity might the low countries been afraid of?, Context: In 1579 a number of the northern provinces of the Low Countries signed the Union of Utrecht, in which they promised to support each other in their defence against the Spanish army. This was followed in 1581 by the Act of Abjuration, the declaration of independence of the provinces from Philip II.

Ex Output:
provinces from Philip II


Ex Input:
Who praised Lee, literary circles or her editors?, Context: Despite her editors' warnings that the book might not sell well, it quickly became a sensation, bringing acclaim to Lee in literary circles, in her hometown of Monroeville, and throughout Alabama. The book went through numerous subsequent printings and became widely available through its inclusion in the Book of the Month Club and editions released by Reader's Digest Condensed Books.

Ex Output:

literary circles
