instruction:
This task is about creating an unanswerable question based on a given passage. Construct a question that looks relevant to the given context but is unanswerable. Following are a few suggestions about how to create unanswerable questions:
(i) create questions which require satisfying a constraint that is not mentioned in the passage
(ii) create questions which require information beyond what is provided in the passage in order to answer
(iii) replace an existing entity, number, date mentioned in the passage with other entity, number, date and use it in the question
(iv) create a question which is answerable from the passage and then replace one or two words by their antonyms or insert/remove negation words to make it unanswerable.
question:
Passage: Newton's First Law of Motion states that objects continue to move in a state of constant velocity unless acted upon by an external net force or resultant force. This law is an extension of Galileo's insight that constant velocity was associated with a lack of net force (see a more detailed description of this below). Newton proposed that every object with mass has an innate inertia that functions as the fundamental equilibrium "natural state" in place of the Aristotelian idea of the "natural state of rest". That is, the first law contradicts the intuitive Aristotelian belief that a net force is required to keep an object moving with constant velocity. By making rest physically indistinguishable from non-zero constant velocity, Newton's First Law directly connects inertia with the concept of relative velocities. Specifically, in systems where objects are moving with different velocities, it is impossible to determine which object is "in motion" and which object is "at rest". In other words, to phrase matters more technically, the laws of physics are the same in every inertial frame of reference, that is, in all frames related by a Galilean transformation.
answer:
Newton's Second Law of Motion states what?

question:
Passage: Almost all ctenophores are predators, taking prey ranging from microscopic larvae and rotifers to the adults of small crustaceans; the exceptions are juveniles of two species, which live as parasites on the salps on which adults of their species feed. In favorable circumstances, ctenophores can eat ten times their own weight in a day. Only 100150 species have been validated, and possibly another 25 have not been fully described and named. The textbook examples are cydippids with egg-shaped bodies and a pair of retractable tentacles fringed with tentilla ("little tentacles") that are covered with colloblasts, sticky cells that capture prey. The phylum has a wide range of body forms, including the flattened, deep-sea platyctenids, in which the adults of most species lack combs, and the coastal beroids, which lack tentacles and prey on other ctenophores by using huge mouths armed with groups of large, stiffened cilia that act as teeth. These variations enable different species to build huge populations in the same area, because they specialize in different types of prey, which they capture by as wide a range of methods as spiders use.
answer:
How do rotifers act as when looking for a meal?

question:
Passage: Comcast also owns many local channels. Comcast also has a variety network known as Comcast Network, available exclusively to Comcast and Cablevision subscribers. The channel shows news, sports, and entertainment and places emphasis in Philadelphia and the Baltimore/Washington, D.C. areas, though the channel is also available in New York, Pittsburgh, and Richmond. In August 2004, Comcast started a channel called Comcast Entertainment Television, for Colorado Comcast subscribers, and focusing on life in Colorado. It also carries some National Hockey League and National Basketball Association games when Altitude Sports & Entertainment is carrying the NHL or NBA. In January 2006, CET became the primary channel for Colorado's Emergency Alert System in the Denver Metro Area. In 2006, Comcast helped found the channel SportsNet New York, acquiring a minority stake. The other partners in the project were New York Mets and Time Warner Cable.
answer:
When did the channel become available in New York, Pittsburgh, and Richmond?
