QUES: Hunting and gathering was presumably the subsistence strategy employed by human societies beginning some 1.8 million years ago, by Homo erectus, and from its appearance some 0.2 million years ago by Homo sapiens. It remained the only mode of subsistence until the end of the Mesolithic period some 10,000 years ago, and after this was replaced only gradually with the spread of the Neolithic Revolution.
When did human populations begin using hunting-gathering?

ANS: 1.8 million years ago

QUES: The BYU Ballroom Dance Company is known as one of the best formation ballroom dance teams in the world, having won the U.S. National Formation Dance Championship every year since 1982. BYU's Ballroom dance team has won first place in Latin or Standard (or both) many times when they have competed at the Blackpool Dance Festival, and they were the first U.S. team to win the formation championships at the famed British Championships in Blackpool, England in 1972 . The NDCA National DanceSport championships have been held at BYU for several years, and BYU holds dozens of ballroom dance classes each semester and is consequently the largest collegiate ballroom dance program in the world. In addition, BYU has a number of other notable dance teams and programs. These teams include the Theatre Ballet, Contemporary Dance Theatre, Living Legends, and International Folk Dance Ensemble. The Living Legends perform Latin, Native American, and Polynesian dancing. BYU boasts one of the largest dance departments in the nation. Many students from all different majors across campus participate in various dance classes each semester.
How is BYU's collegiate ballroom dance program rated worldwide?

ANS: the largest

QUES: Similar to the problems of defining literature and film, no consensus has been reached on a definition of the comics medium, and attempted definitions and descriptions have fallen prey to numerous exceptions. Theorists such as Topffer, R. C. Harvey, Will Eisner, David Carrier, Alain Rey, and Lawrence Grove emphasize the combination of text and images, though there are prominent examples of pantomime comics throughout its history. Other critics, such as Thierry Groensteen and Scott McCloud, have emphasized the primacy of sequences of images. Towards the close of the 20th century, different cultures' discoveries of each other's comics traditions, the rediscovery of forgotten early comics forms, and the rise of new forms made defining comics a more complicated task.
What has not been reached as far as defining comics is concerned?

ANS: consensus

QUES: In an ecosystem, predation is a biological interaction where a predator (an organism that is hunting) feeds on its prey (the organism that is attacked). Predators may or may not kill their prey prior to feeding on them, but the act of predation often results in the death of the prey and the eventual absorption of the prey's tissue through consumption. Thus predation is often, though not always, carnivory. Other categories of consumption are herbivory (eating parts of plants), fungivory (eating parts of fungi), and detritivory (the consumption of dead organic material (detritus)). All these consumption categories fall under the rubric of consumer-resource systems. It can often be difficult to separate various types of feeding behaviors. For example, some parasitic species prey on a host organism and then lay their eggs on it for their offspring to feed on it while it continues to live in or on its decaying corpse after it has died. The key characteristic of predation however is the predator's direct impact on the prey population. On the other hand, detritivores simply eat dead organic material arising from the decay of dead individuals and have no direct impact on the "donor" organism(s).
What does prey eventually do to its predator's tissue in defense?
