TASK DEFINITION: In this task you will be given a passage and a yes/no question based on the passage. You should answer the question using the information from the passage.
PROBLEM: passage: In the mid to late 1990s many higher-end AV receivers included the demodulator circuit specifically for the LaserDisc players RF modulated Dolby Digital AC-3 signal. By the late 1990s with LaserDisc players and disc sales declining due to DVD's growing popularity the AV receiver manufacturers removed the demodulator circuit. Although DVD players were capable of playing Dolby Digital tracks, the signals out of DVD players were not in a modulated form and not compatible with the inputs designed for LaserDisc AC-3. Outboard demodulators were available for a period that convert the AC-3 signal to standard Dolby Digital signal that was compatible with the standard Dolby Digital/PCM inputs on capable AV receivers. Another type marketed by Onkyo and others converted the RF AC-3 signal to 6-channel analog audio.
 question: will a laserdisc play in a dvd player?

SOLUTION: No

PROBLEM: passage: Despite Sony's focus on the PS4 and mobile for the future, the Vita still continues to receive substantial third party company game support in the way of Japanese-style role-playing games and visual novels and Western-style indie video games. Minecraft in particular was successful for the platform, with it selling over 1.2 million physical copies in Japan alone as of September 2017. The device is considered to have sold fairly well in Japan, and still a crucial part of Sony's overall strategy in the region, while Sony has acknowledged that the device still has a very vocal and passionate user-base in the West as well, with the company still encouraging third party companies to create games for the device. At the 2016 Game Developers Conference, research analyst firm EEDAR estimated the sales of the Vita to be about at 10 million unit sold through the end of 2015. Multi-platform releases with the PS4 have also incidentally helped sustain the Vita's stream of software, even in the west, through 2016 and 2017; games receive a Vita version more to appeal to Japan's larger Vita user-base, and receive a PS4 version more to appeal to North America's larger user-base. The March 2017 launch of the Nintendo Switch, which operates on a similar concept of providing high budget video games on a portable unit, further overshadowed the Vita, though niche support through indie games and JRPGs continued into the year. In mid-2017, Glixel estimated the Vita userbase to be around 15 million.
 question: do they still make games for psp vita?

SOLUTION: Yes

PROBLEM: passage: There is some debate as to whether dewclaws should be surgically removed. The argument for removal states that dewclaws are a weak digit, barely attached to the leg, and thus they can rip partway off or easily catch on something and break, which can be painful and prone to infection. Dewclaw removal is most easily performed when the dog is young, around 2--5 days of age. It can also be performed on older dogs if necessary though the surgery may be more difficult then. The surgery is fairly straightforward and may be done with local anesthetics if the digit is not well connected to the leg. Many dogs can't resist licking the surgery site in the weeks following the procedure, so an Elizabethan collar or bitterant may be used to curtail this behavior, thus preventing infection.
 question: do dogs have to have their dew claws removed?
