In this task, you are given Wikipedia articles on a range of topics, we ask you to write a question based on the content of the articles that can be answered in a binary manner i.e. True or False.
question:
Superfecundation -- Heteropaternal superfecundation is common in animals such as cats and dogs. Stray dogs can produce litters in which every puppy has a different sire. Though rare in humans, cases have been documented. In one study on humans, the frequency was 2.4% among dizygotic twins whose parents had been involved in paternity suits.
answer:
can you have twins and have two different fathers


question:
Golden goal -- The golden goal is still used in NCAA matches and in FIH sanctioned field hockey games, as well as in FIRS sanctioned roller hockey games. A related concept is used in National Rugby League games. A similar golden goal rule is also used in all National Hockey League (NHL) overtime games (followed by a shootout if needed, in the regular season and preseason); however, the term ``golden goal'' is not used. A rule similar to the golden goal also applies in the National Football League (only if a touchdown or safety is scored first on the first possession), although again the term itself is not used.
answer:
does the golden goal rule still exist in football


question:
Gun laws in Maryland -- Carrying a handgun, whether openly or concealed, is prohibited unless one has a permit to carry a handgun or is on their own property or their own place of business. The Maryland State Police may issue a permit to carry a handgun at their discretion and based on an investigation. In practice, very few applicants are granted carry permits, and approval typically requires the applicant to provide proof of a clear and imminent threat on his or her life. For example, police reports submitted by an applicant documenting a recent assault, attempted kidnapping, carjacking, or home invasion, particularly when the assailant remains at-large, have generally been accepted as sufficient ``good reason'' for issuance of a carry permit. If the State Police deny the permit application, the applicant may appeal the denial to the Handgun Permit Review Board. The review board, staffed by gubernatorial appointees, has the discretion to grant or deny an appeal on a case-by-case basis. Permits are not automatically renewed, and the permit-holder must justify the continued need for the permit when applying for renewal. Out of a total population of 6 million, there were 14,298 active carry permits as of April 2014. No permit is required to openly carry a rifle or shotgun in Maryland.
answer:

can you open carry a rifle in maryland
