Problem: Energy:

Energy transfer can be considered for the special case of systems which are closed to transfers of matter. The portion of the energy which is transferred by conservative forces over a distance is measured as the work the source system does on the receiving system. The portion of the energy which does not do work during the transfer is called heat.[note 4] Energy can be transferred between systems in a variety of ways. Examples include the transmission of electromagnetic energy via photons, physical collisions which transfer kinetic energy,[note 5] and the conductive transfer of thermal energy.

What can be considered for the typical case of systems which are opened to transfers of matter?

Problem: LaserDisc:

Although the format was capable of offering higher-quality video and audio than its consumer rivals, the VHS and Betamax videocassette systems, LaserDisc never managed to gain widespread use in North America, largely due to high costs for the players and video titles themselves and the inability to record TV programming. It also remained a largely obscure format in Europe and Australia. By contrast, the format was much more popular in Japan and in the more affluent regions of Southeast Asia, such as Hong Kong, Singapore, and Malaysia, being the prevalent rental video medium in Hong Kong during the 1990s. Its superior video and audio quality did make it a somewhat popular choice among videophiles and film enthusiasts during its lifespan.

With whom was LaserDisk a popular choice for it's picture and sound quality?
---
A: videophiles and film enthusiasts


Problem: Comics:

Comics are a medium used to express ideas by images, often combined with text or other visual information. Comics frequently takes the form of juxtaposed sequences of panels of images. Often textual devices such as speech balloons, captions, and onomatopoeia indicate dialogue, narration, sound effects, or other information. Size and arrangement of panels contribute to narrative pacing. Cartooning and similar forms of illustration are the most common image-making means in comics; fumetti is a form which uses photographic images. Common forms of comics include comic strips, editorial and gag cartoons, and comic books. Since the late 20th century, bound volumes such as graphic novels, comics albums, and tankōbon have become increasingly common, and online webcomics have proliferated in the 21st century.

Which form of comics entails the use of autographic images?

A: unanswerable


Problem: John Kerry:

Kerry established a separate political action committee, Keeping America's Promise, which declared as its mandate "A Democratic Congress will restore accountability to Washington and help change a disastrous course in Iraq", and raised money and channeled contributions to Democratic candidates in state and federal races. Through Keeping America's Promise in 2005, Kerry raised over $5.5 million for other Democrats up and down the ballot. Through his campaign account and his political action committee, the Kerry campaign operation generated more than $10 million for various party committees and 179 candidates for the U.S. House, Senate, state and local offices in 42 states focusing on the midterm elections during the 2006 election cycle. "Cumulatively, John Kerry has done as much if not more than any other individual senator", Hassan Nemazee, the national finance chairman of the DSCC said.

How many states' down-ballot candidates did Kerry help support?

A:
42
