Extract the answer to the question from the following context. Question: Ice streams are found? Context: Glacial bodies larger than 50,000 km2 (19,000 sq mi) are called ice sheets or continental glaciers. Several kilometers deep, they obscure the underlying topography. Only nunataks protrude from their surfaces. The only extant ice sheets are the two that cover most of Antarctica and Greenland. They contain vast quantities of fresh water, enough that if both melted, global sea levels would rise by over 70 m (230 ft). Portions of an ice sheet or cap that extend into water are called ice shelves; they tend to be thin with limited slopes and reduced velocities. Narrow, fast-moving sections of an ice sheet are called ice streams. In Antarctica, many ice streams drain into large ice shelves. Some drain directly into the sea, often with an ice tongue, like Mertz Glacier.

Q: Extract the answer to the question from the following context. Question: How can a majority party be seen as inefficient? Context: A look at one minority leadership strategypartisan oppositionmay suggest why it might be employed in specific circumstances. The purposes of obstruction are several, such as frustrating the majority party's ability to govern or attracting press and media attention to the alleged ineffectiveness of the majority party. "We know how to delay," remarked Minority Leader Gephardt Dilatory motions to adjourn, appeals of the presiding officer's ruling, or numerous requests for roll call votes are standard time-consuming parliamentary tactics. By stalling action on the majority party's agenda, the minority leader may be able to launch a campaign against a "do-nothing Congress" and convince enough voters to put his party back in charge of the House. To be sure, the minority leader recognizes that "going negative" carries risks and may not be a winning strategy if his party fails to offer policy alternatives that appeal to broad segments of the general public.
A: obstruction

Question: Extract the answer to the question from the following context. Question: What happened to the Philadelphia dialect in South Jersey? Context: The Philadelphia dialect, which is spread throughout the Delaware Valley and South Jersey, is part of Mid-Atlantic American English, and as such it is identical in many ways to the Baltimore dialect. Unlike the Baltimore dialect, however, the Philadelphia accent also shares many similarities with the New York accent. Thanks to over a century of linguistics data collected by researchers at the University of Pennsylvania, the Philadelphia dialect under sociolinguist William Labov has been one of the best-studied forms of American English.[f]
Answer: spread

[Q]: Extract the answer to the question from the following context. Question: What was the first thing listed that can be used to measure sexual orientation? Context: In the paper "Who's Gay? Does It Matter?", Ritch Savin-Williams proposes two different approaches to assessing sexual orientation until well positioned and psychometrically sound and tested definitions are developed that would allow research to reliably identify the prevalence, causes, and consequences of homosexuality. He first suggests that greater priority should be given to sexual arousal and attraction over behaviour and identity because it is less prone to self- and other-deception, social conditions and variable meanings. To measure attraction and arousal he proposed that biological measures should be developed and used. There are numerous biological/physiological measures that exist that can measure sexual orientation such as sexual arousal, brain scans, eye tracking, body odour preference, and anatomical variations such as digit-length ratio and right or left handedness. Secondly, Savin-Williams suggests that researchers should forsake the general notion of sexual orientation altogether and assess only those components that are relevant for the research question being investigated. For example:

[A]: sexual arousal

Extract the answer to the question from the following context. Question: Why might someone not want to power a DC motor using AC current? Context: Operating at normal power line frequencies, universal motors are often found in a range less than 1000 watts. Universal motors also formed the basis of the traditional railway traction motor in electric railways. In this application, the use of AC to power a motor originally designed to run on DC would lead to efficiency losses due to eddy current heating of their magnetic components, particularly the motor field pole-pieces that, for DC, would have used solid (un-laminated) iron and they are now rarely used.

Answer:
efficiency losses
