The problem: Answer a question about this article:
Dog behavior is the internally coordinated responses (actions or inactions) of the domestic dog (individuals or groups) to internal and/or external stimuli. As the oldest domesticated species, with estimates ranging from 9,000–30,000 years BCE, the minds of dogs inevitably have been shaped by millennia of contact with humans. As a result of this physical and social evolution, dogs, more than any other species, have acquired the ability to understand and communicate with humans and they are uniquely attuned to our behaviors. Behavioral scientists have uncovered a surprising set of social-cognitive abilities in the otherwise humble domestic dog. These abilities are not possessed by the dog's closest canine relatives nor by other highly intelligent mammals such as great apes. Rather, these skills parallel some of the social-cognitive skills of human children.
Dogs have some social skills that parallel what?
****
The answer: human children


The problem: Answer a question about this article:
Late Carboniferous and Early Permian insect orders include both extant groups, their stem groups, and a number of Paleozoic groups, now extinct. During this era, some giant dragonfly-like forms reached wingspans of 55 to 70 cm (22 to 28 in), making them far larger than any living insect. This gigantism may have been due to higher atmospheric oxygen levels that allowed increased respiratory efficiency relative to today. The lack of flying vertebrates could have been another factor. Most extinct orders of insects developed during the Permian period that began around 270 million years ago. Many of the early groups became extinct during the Permian-Triassic extinction event, the largest mass extinction in the history of the Earth, around 252 million years ago.
Higher levels of what substance possibly contributed to the phenomenon of gigantism? 
****
The answer: oxygen


The problem: Answer a question about this article:
In 1875, blacks made up 57% of the city's population, and 73% of Charleston County. With leadership by members of the antebellum free black community, historian Melinda Meeks Hennessy described the community as "unique" in being able to defend themselves without provoking "massive white retaliation", as occurred in numerous other areas during Reconstruction. In the 1876 election cycle, two major riots between black Republicans and white Democrats occurred in the city, in September and the day after the election in November, as well as a violent incident in Cainhoy at an October joint discussion meeting.
How many major riots between blacks and whites occurred in Charleston in 1876?
****
The answer: two
