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.

Input: Consider Input: Isosceles triangle -- Whether the isosceles triangle is acute, right or obtuse depends on the vertex angle. In Euclidean geometry, the base angles cannot be obtuse (greater than 90°) or right (equal to 90°) because their measures would sum to at least 180°, the total of all angles in any Euclidean triangle. Since a triangle is obtuse or right if and only if one of its angles is obtuse or right, respectively, an isosceles triangle is obtuse, right or acute if and only if its vertex angle is respectively obtuse, right or acute.

Output: can the base angle of an isosceles triangle be obtuse


Input: Consider Input: Hours (2013 film) -- Nolan is now so exhausted he cannot crank it with his hand any longer. Nolan has to use both his hands to slowly crank the handle, but breaks it off accidentally. Nolan's attempts to fix the crank generator fails, so he gives his child mouth-to-mouth resuscitation to keep her alive. Before he can do any more, Nolan passes out from shock, stress, and exhaustion. Nolan then hears the ventilator beeping; it is running out of power. However, he is too weak to get back up. Nolan accepts that he has failed his child. But Sherlock comes to his aid and brings two paramedics with him to save Nolan, and drag him out. When Nolan wakes up, the paramedics hear his baby crying and run off to find her. Abigail has finally learned to breathe on her own. The paramedics give Nolan his baby and the two embrace, with Nolan crying tears of joy as they are brought to safety.

Output: does the baby survive in the movie hours
